Submitting a C++Builder XE3 application to the Mac AppStore

Yesterday, I filled a hole in the schedule with an impromptu session on visualization of mathematical functions. At the end I also showed how to submit the application to the Mac AppStore.

At the end I ran into an error saying "Invalid Binary" and I filled in the details for my contact information that it asked me for.

However, this didn't solve the entire problem.

You also need to turn off Dynamic RTL and Run Time Packages. Unless you code sign them manually on the Mac side.

Finally, in order to bypass an issue with the Incremental Linker for Mac, you will need to turn off the Incremental Linker.

Doing these three things in addition gave me a successful submission to the AppStore.

C++Builder R&D sessions at CodeRage 7 tomorrow

Don't miss these R&D sessions tomorrow (Wednesday) at CodeRage 7:

9am PST - Migrating C++Builder Code to 64-bit

This session will cover differences between the Embacadero Win32 and Win64 C++ compilers, comparing keywords, macros, extensions and standards conformance of bcc32 and bcc64. The focus will be on strategies to port existing C++ Projects (ActiveX, WebBroker, SOAP, etc) and writing new code in a way that works for both Platforms.

Bruneau Babet - Embarcadero

12pm PST - C++Builder 64-bit Windows Compiler: Supporting the Delphi Extensions Including RTTI

The C++ language standard provides a naming convention to identify language extensions using the double underbar (__) in front of any extensions. This session will discuss the language and runtime extensions added to the new C++Builder 64-bit Windows compiler to support Delphi language, types, components and enhanced RTTI.

Eli Boling - Embarcadero

1pm PST - Using the C++ Standard and Boost Libraries in your 32-bit & 64-bit Applications
The C++ Standard library is a set of classes and functions that are part of the ISO standard for C++. The Boost C++ libraries include a collection of portable C++ source libraries created by Boost community members (http://www.boost.org), some of which are now included as part of the C++ Standard library. In this session you will learn how you can use the C++ Standard and Boost libraries in your C++ applications for Windows and Mac OS X.

Lee Cantey - Embarcadero

Enjoy!

Components vs Children in FireMonkey

You have probably iterated through the Components array many many times as a Delphi developer.

Consider this simple application:



It's probably no surprise that listing the Components of the form like this...


procedure TForm2.Button1Click(Sender: TObject);
var
i: Integer;
begin
Memo2.Lines.Clear;
for i := 0 to ComponentCount-1 do
Memo1.Lines.Add(Components[i].ClassName+' (Name = "'+Components[i].Name+'")')
end;


...gives you the following output, which is very similar to the Structure View in the IDE, except that it doesn't show the relationships between the components.



Listing the children, and the children of all children (recursively) is simply done by using this procedure:


procedure TForm2.ListChildren(Obj : TFMXObject; Level : Integer);
var
i: Integer;
begin
for i := 0 to Obj.ChildrenCount-1 do begin
Memo2.Lines.Add(StringOfChar(' ',2*Level)+
Obj.Children[i].ClassName+
' (Name = "'+
Obj.Children[i].Name+
'")');
ListChildren(Obj.Children[i],Level+1);
end;
end;

procedure TForm2.Button2Click(Sender: TObject);
begin
Memo2.Lines.Clear;
ListChildren(Self,0);
end;


The above code will give us a tree output with indentation to show us the children, grandchildren, etc, like this:



The list of children is much longer than you would possibly except at first. We see for instance that in FireMonkey a TButton consists of a TLayout, a TSubImage and a TText. The TSubImage and the TText in turn have 4 animations each to handle hover-in/hover-out and pressing/releasing. Likewise the TMemo holds scrollbars, a popup context menu, and much more.

The entire output from ListChildren follows below:
TSubImage (Name = "")
TButton (Name = "Button1")
TLayout (Name = "")
TSubImage (Name = "")
TRectAnimation (Name = "")
TRectAnimation (Name = "")

EKON16 and Mobile Studio

This post is a little late. My apologies. :)

I had the great honor of keynoting at EKON16 in Dusseldorf earlier in November. I presented RAD Studio XE3 and our RAD Studio road map.

I also did a well attended session "What's Cooking in the Labs". I gave a sneak preview of Mobile Studio for about 45 minutes and showed where we're going with it. I showed the seamless integration of writing your code, designing your UI, debugging and deploying your app. I showed our use of some native controls, like the the date picker for selecting dates and even custom pickers (TComboBox in Delphi). I showed our native use of the notification dialog for ShowMessage instead of a custom window as before.

Mobile Studio is going to be very cool.

Thanks to the EKON16 crew in Germany!

Reflection for Mac

Just bought this brilliant piece of software - http://www.reflectionapp.com/

Now I can demo iPhone/iPad apps on the Mac without cables.

It works over AirPlay with no software needed on the iPhone/iPad.

Works with iPhone 4S and iPad 2+.

I've already made sure that Camtasia can screen record the iPad screen on the Mac as well. Looking forward to using this in upcoming webinars!

MathViz for iOS updated and free for two days!

MathViz 1.1 update has been approved. I added gesture support and a reset button.



Pardon me while I play around and get a feel for how pricing campaigns work... ;)

MathViz 1.1 is free for two days. I believe I exhausted the potential for new customers (without doing any marketing) so the party right now is up to just a couple of pizzas (if I do Papa Murphy's Take'n'Bake)... ;)

Please feel free to download MathViz in the next couple of days while it's free. Please consider reviewing it as well.

BTW, MathViz will be permanently free at some point, and the source code will be freed at some point as well.

Thanks for playing! Enjoy!

Playing sound on iOS? Anyone have a working Delphi XE2 FireMonkey sample?

I wish I had time for everything... I've tried this one a couple of times, but have run into issues with parsing framework this and that... ;)

So, here it is... Anyone got a simple example that plays a single sound effect and/or plays a background track?

From files that you deploy with the app (resources).

Background track from existing music library on device would be a sweet bonus.

I'll make sure you get credit if I use it in upcoming blogs, webinars, etc.

Thanks!

3 more iOS components added - Pinch/Zoom/Rotate gesture recognizers plus a custom switch

I've uploaded three more components to CodeCentral. There are now 13 components and 8 demos in my submission.

The three components added:

PinchGestureRecognizer - zoom/pinch

RotationGestureRecognizer - rotation

Switch - custom labels for TSwitch - ON/OFF or YES/NO (or any 1-4 letter words you want)

Enjoy!

Modifying FMX_Platform_iOS.pas to support surface mainWindow and add device orientation support

Here are the steps that I use in order to surface a couple of things that some of my custom iOS components and apps need.

These modifications are not supported by anyone. Except maybe me. You apply them entirely at your own risk.

Modify FMX_Platform_iOS.pas on your MAC as below. It's typically located in the /Developer/Embarcadero/fmi directory.

CAUTION: Save a copy of FMX_Platform_iOS.pas FIRST!
CAUTION: Any update of XE2 will delete your changes, so keep this file around if you have to redo the changes.

...

unit FMX_Platform_iOS;

...

interface

...

// TUIViewController and TUIWindow declarations moved from implementation to interface section

type
{ TUIViewController }

TUIViewController = objcclass(UIViewController)
private
public
function shouldAutorotateToInterfaceOrientation(AinterfaceOrientation: UIInterfaceOrientation): Boolean; override;
procedure didReceiveMemoryWarning; override;
procedure didAnimateFirstHalfOfRotationToInterfaceOrientation(toInterfaceOrientation: UIInterfaceOrientation); override;
procedure didRotateFromInterfaceOrientation(fromInterfaceOrientation: UIInterfaceOrientation); override;
end;

{ TUIWindow }

TUIWindow = objcclass(UIWindow)
protected
public
Text: UITextField;
mainView: UIView;
mainController: TUIViewController;
end;

// mainWindow moved from implementation to interface section
// currentOrientation added to give current device orientation
// supportsPortrait etc added. You simply change these in your app code to False if not needed

var
mainWindow: TUIWindow;
currentOrientation : UIInterfaceOrientation;
supportsPortrait : Boolean = True;
supportsPortraitUpsideDown : Boolean = True;
supportsLandscapeRight : Boolean = True;
supportsLandscapeLeft : Boolean = True;

implementation

...

function TUIViewController.shouldAutorotateToInterfaceOrientation(
AinterfaceOrientation: UIInterfaceOrientation): Boolean;
begin
Result := ((AinterfaceOrientation = UIInterfaceOrientationLandscapeRight) and supportsLandscapeRight) or
((AinterfaceOrientation = UIInterfaceOrientationLandscapeLeft) and supportsLandscapeLeft) or
((AinterfaceOrientation = UIInterfaceOrientationPortrait) and supportsPortrait) or
((AinterfaceOrientation = UIInterfaceOrientationPortraitUpsideDown) and supportsPortraitUpsideDown);

if Result then
currentOrientation := AinterfaceOrientation;
end;

...
Enjoy!

iOS Formula Keyboard

Just a teaser. I'll probably add this as an InAppPurchase for MathViz when I make MathViz free. ;)



Thanks to those who bought MathViz already! 25 copies sold for $0.99 each in 4 days! Enough for a couple of six packs for the office. ;)

PS: Source code for this one coming too. Mainly custom style work in this one.

May the Force be with you! (and MyEDN for iOS)

Happy Star Wars Day!

MyEDN was originally submitted to the AppStore for review on April 9th.

My first mistake was not including, setting up and populating a test account for Apple to test MyEDN. DOH!

That cost me about a week, because the review process is clocking at about 6-7 days it seems.

They sent me a request to update the review notes with a test account and test instructions, and finally submit the new meta data. Unfortunately the reviewer had put MyEDN in the wrong state, and it took me a while to figure out that the only way to get it back into Waiting for Review was to submit a new binary (actually the same one).

About a week later it was rejected with some unspecific pointers about the UI. This was the login screen at this point:



I asked for clarification, and got another couple of messages back from the reviewer that weren't specific enough for me to figure out what exactly they wanted instead.

I decided to use the Appeal option, and while waiting for that process I ripped the UI apart and recreated it from the ground up. I added info screens throughout as well as more functionality.

Yesterday I got a call back from a very nice person of the App Review Board, and it became clear that the issue wasn't UI at all. I had a link to www.embarcadero.com in my description of MyEDN. This is considered disallowed marketing, even though my phrasing was specifically "PS: An EDN account is required to use this app. If you don't have one, you can create one here..." - in retrospect a link to members.embarcadero.com would probably have worked better, but I opted to remove the link completely. I don't foresee anyone that isn't already an EDN member downloading MyEDN anyway. Finally, Apple had also found a crash bug, which is now addressed.

By this time I already had the new UI ready to go. My plan was to make it an update, but since MyEDN still wasn't approved I simply uploaded it as a new binary and it's now pending review in this form:



I'm much happier with this look and feel, and my hope is that the Force is with MyEDN this time. If the review cycle stays on it's current 6-7 day schedule MyEDN should go into review by the end of next week, and hopefully I've knocked out all issues and it will be approved so that you guys can have at it. I can't stand the fact that Cleggy teases me on a daily basis that EDN Mobile has been in Google Play for weeks and that he's updated it multiple times in the last couple of days. I told him that in his case no review was required, and that his UI is still nowhere near mine. Apple is holding MyEDN to a much higher standard than that! So there, Cleggy... ;)

Enjoy!

PS: All this experience with App Review feedback, Appeal etc will be awesome fodder for upcoming webinars as well, so that all of you can create awesome iOS apps.

MathViz 1.0 for iOS approved and in the AppStore now!!!

MathViz 1.0 AppStore link

Before you ask why it's $0.99 and not free - I wanted to see if I could get a FireMonkey paid app approved, and I'm very happy to say that I could. And anyone can, of course!

I will leave it at $0.99 for the next couple of weeks, and anyone that wants to "donate" to a lunch, dinner, party or whatever it turns out to be, can do so in the next couple of weeks. After that it will become free for all.

The link above is live, but it will take up to 24 hours for MathViz to be searchable in the AppStores world wide.

Your purchases of MathViz will go to a couple of things - Apple, the IRS and finally some kind of FireMonkey party of some kind - total volume of paid sales and actual payouts from Apple will determine what will happen.

Now that MathViz is available I will use it for blog fodder, webinar fodder, and I will of course publish the source code.

Thanks everyone in advance for playing and giving feedback!

MathViz 1.0 is powered by TExpressionParser - a flexible and fast expression parser for logical and mathematical functions by Egbert van Nes, with contributions by John Bultena and Ralf Junker. Thanks for Egbert van Nes' explicit permission to use it in a paid app. :)

Math parsing function/component anyone?

I'm looking for a reasonably light-weight, simple and fast math function parser. It should not be a DLL. I need it to work on Windows, MacOSX and iOS. I would use it in a demo I want to build.

It must be able to parse and evaluate functions of (at least) two variables, for instance f(x,y) = sin(x^2+y^2)/(x^2+y^2).

I would use it like this (pseudo code):
FuncTree := BuildEvalTree('f(x,y) = sin(x^2+y^2)/(x^2+y^2)'); // Or whatever it needs
for x := x_min to x_max do
for y := y_min to y_max do
z[x,y] := Evaluate(FuncTree,[x,y]); // Or whatever it needs...

Thanks!

Solution: armv7 validation errors when submitting FireMonkey iOS apps to the AppStore

EDIT: This post is now outdated. HotFix 1 addresses this issue, and these steps are no longer needed!

I was trying to record the process of submitting an app last Friday. My EDN app was ready for the AppStore. I ran into this:

iPhone/iPod Touch: application executable is missing a required architecture.
At least one of the following architecture(s) must be present: armv7

This happens on the validation step of submitting an app to the AppStore. The reason is that the validation step for AppStore submissions has changed. Support for *only* armv6 is no longer allowed. You have to support armv7, either by itself or have dual support (armv6 and armv7). This is a recent change, since I was able to submit my previous Analog Clock app in late October last year.

I've spent much of the last week trying to solve this problem. I did a bunch of research, but there was no single magic bullet anywhere. I finally cracked it. And here is the solution. I apologize in advance if some steps are missing. I tried to capture every single step I had to take.

STEP 1: Rebuilding iPhoneAll for armv7


Phil Hess has an excellent page that explains this process - http://web.me.com/macpgmr/ObjP/Xcode4/iOS_5_Parsing_Status.html

You don't actually need to parse anything for this purpose. You can jump directly to Phil's Step 4 and build iPhoneAll for armv6/armv7 as follows:

./compile-arm.sh iPhoneAll.pas

Then Phil's Step 5 from the link above (this moves the compiled targets in place):
mv iPhoneAll.o /usr/local/lib/fpc/2.6.0/units/arm-darwin/cocoaint/
mv iPhoneAll.ppu /usr/local/lib/fpc/2.6.0/units/arm-darwin/cocoaint/
mv AnonClassDefinitionsUikit.o /usr/local/lib/fpc/2.6.0/units/arm-darwin/cocoaint/
mv AnonClassDefinitionsUikit.ppu /usr/local/lib/fpc/2.6.0/units/arm-darwin/cocoaint/

STEP 2: Rebuilding the FPC RTL for armv7

We'll use the following link as a base line - http://wiki.freepascal.org/iPhone/iPod_development#Building_an_ARM_Cross-compiler

We need to modify the steps for iOS5.0 as follows:

Jump into Super User mode:

sudo bash

export IPHONEPLATFORMBASEDIR=/Developer/Platforms/iPhoneOS.platform/Developer

make clean

make FPC=/usr/local/lib/fpc/2.6.0/ppc386 CPU_TARGET=arm CROSSOPT="-FD${IPHONEPLATFORMBASEDIR}/usr/bin -XR${IPHONEPLATFORMBASEDIR}/SDKs/iPhoneOS5.0.sdk/ -ap -Cparmv7 -Cfvfpv3" all

sudo make FPC=`pwd`/compiler/ppcrossarm OPT="-ap" CPU_TARGET=arm CROSSOPT="-FD${IPHONEPLATFORMBASEDIR}/usr/bin -XR${IPHONEPLATFORMBASEDIR}/SDKs/iPhoneOS5.0.sdk/ -ap" install CROSSINSTALL=1

sudo ln -sf ../lib/fpc/2.5.1/ppcrossarm /usr/local/bin/ppcarm

STEP 3. Modify the Run Script for project under Build Phases for your Target in Xcode

Replace the -Cfvfpv2 flag with both of these flags -Cparmv7 -Cfvfpv3. A typical excerpt from the Run Script will now say:

/usr/local/lib/fpc/2.6.0/ppcrossarm -gw -g -godwarfsets -Xg -O1 -Cparmv7 -Cfvfpv3 -MDelphi -B -o$BUILT_PRODUCTS_DIR/$EXECUTABLE_PATH -Fu/usr/local/lib/fpc/2.6.0/units/arm-darwin/fmi -Fu/Developer/Embarcadero/fmi -Fu/Developer/Embarcadero/fmi/coretext -Fu/Developer/Embarcadero/fmi/fpclib -XR$SDKROOT -FD$PLATFORM_DEVELOPER_BIN_DIR "$PROJECT_DIR/../$PROJECT.pas"

Drop armv6 from Architectures under Build Settings for your Project if it's set.

Good luck!

Who would pay $0.99 for my iOS app?

I've been hacking away at my EDN iOS app. Here are a few screen shots of what it looks like in development. I have a few things I need to polish and then I will submit it to the AppStore.

Technical details:

* Communicates with the EDN MemberShip Services DataSnap REST Server

* You can log in, view your details, edit your details and post changed details back

* You can get all your registered products and serial numbers

* You can choose to persist username/password or not

* Works on all iOS devices and all device rotations!

Maybe it's worth more than $0.99? Especially if you get the full source code... ;)

This is what my app looks like when you launch it:

[caption id="attachment_39242" align="alignnone" width="200" caption="Just need a password..."]Just need a password[/caption]

This is what it looks like when you fail to login:

[caption id="attachment_39241" align="alignnone" width="200" caption="Access denied!"]Access denied![/caption]

This is what my user details look like:

[caption id="attachment_39243" align="alignnone" width="200" caption="My user details"]My user details[/caption]

FireMonkey and iOS 5.1

I finally upgraded to Lion and Xcode 4.3. Also iOS 5.1 on my iPhone 4.

I can happily confirm that FireMonkey apps work great on iOS 5.1 devices.

I already had Snow Leopard and Xcode 4.2 before. All it took was upgrading to Lion and then getting Xcode 4.3. That's it. I did not have to reinstall FPC or FMI at all.

This, ladies and gentlemen, is a working iOS DataSnap client for EDN services!



In the coming weeks, I will be blogging about how to create your own iOS client to access any DataSnap server.

Did someone say we don't have TDataSet on iOS? Yeah, that might have been me. So wrong! We do!

In fact, here's a (condensed) code snippet from this app:
Proxy := CreateProxy;
DS := Proxy.GetRegistrations(Session);
FreeProxy(Proxy);

while not DS.EOF do begin
Memo1.Lines.Add(DS.FieldByName('TITLE').AsString+' '+DS.FieldByName('REGISTRATIONS').AsString);
DS.Next;
end;

Once the app is finished, my goal is to upload it to the AppStore and record the whole process so that I can publish the video as a tutorial on AppStore submission for FireMonkey apps as well. All it takes is time... ;)

iOS Camera/Photo demo - PREVIEW - AS-IS

I'm only posting this because a lot of folks have been asking for it.

This demo is provided as-is with no guarantees of working on any device whatsoever.

http://cc.embarcadero.com/item/28774

You have been warned. It's by no means complete. Not even tested since 10/11/2011 - not tested on iOS 5.0 or 5.1. Last I tested it was on 4.3 I think.

I'll replace it when I get time to finish it. Feel free to send me back a 10x better version.

BTW - you *have* to hack FMX_Platform_iOS.pas and know what you're doing to use this demo. You have to surface mainwindow and whatever else Xcode tells you is missing. You can do so by moving the declarations from the implementation section to the interface section. All warranties may very well be void by doing so, so back the file up before breaking it.

Disclaimer done... ;)

Enjoy!

Camera.Target fix

There's a missing call to MatrixChanged(Self) in TCamera.SetTarget. Without this second line, setting the Target does nothing.

procedure TCamera.SetTarget(const Value: TControl3D);
begin
FTarget := Value;
MatrixChanged(Self);
end;

This fix is required for my upcoming Kepler System demo.

iOS Address Book fun

Getting data out of the iOS address book is a lot harder than I thought... Must make component... ;)

Here's a Q&D routine I managed to eek out today. It simply prints all contacts and all their numbers to the log console.

Enjoy!
uses
iPhoneAll, AddressBook, CFArray, CFBase;

procedure DumpAddressBook;
var
addressBook : ABAddressBookRef;
allPeople : CFArrayRef;
nPeople : CFIndex;
ref : ABRecordRef;
i, j : Integer;
firstName : CFStringRef;
lastName : CFStringRef;
phoneNumber : CFStringRef;
l, v : CFStringRef;
S : NSString;
begin
addressBook := ABAddressBookCreate;
allPeople := ABAddressBookCopyArrayOfAllPeople(addressBook);
nPeople := ABAddressBookGetPersonCount(addressBook);

for i:=0 to nPeople-1 do begin
ref := CFArrayGetValueAtIndex(allPeople,i);

firstName := ABRecordCopyValue(ref,kABPersonFirstNameProperty);
lastName := ABRecordCopyValue(ref,kABPersonLastNameProperty);
if firstName <> nil then
if lastName <> nil then
S := NSString.stringWithFormat(NSSTR(PChar('%@, %@')),lastName,firstName)
else
S := NSString.stringWithFormat(NSSTR(PChar('%@')),firstName)
else
if lastName <> nil then
S := NSString.stringWithFormat(NSSTR(PChar('%@')),lastName);
NSLog(S);

phoneNumber := ABRecordCopyValue(ref, kABPersonPhoneProperty);
for j:=0 to ABMultiValueGetCount(phoneNumber)-1 do begin
l := ABMultiValueCopyLabelAtIndex(phoneNumber,j);
v := ABMultiValueCopyValueAtIndex(phoneNumber,j);
S := NSString.stringWithFormat(NSSTR(PChar('%@: %@')),l,v);
NSLog(S);
CFRelease(l);
CFRelease(v);
end;

if phoneNumber <> nil then
CFRelease(phoneNumber);
if firstName <> nil then
CFRelease(firstName);
if lastName <> nil then
CFRelease(lastName);
end;
end;

Handling Swipe Gestures in FireMonkey for iOS

I've added a component to handle left, right, up and down swipe gestures to my set of iOS components.

Here's the full set!

NOTE: This component requires that you edit the FMX_Platform_iOS.pas file on the Xcode side to surface mainWindow and a few other things.

Once installed, this component is extremely easy to use. Simply hook up the OnSwipe events that you'd like to handle and you're done!
type
TSwipeEvent = procedure of object;

TiOSSwipeGestureRecognizer = class(TFmxObject)
private
FOnSwipeRight : TSwipeEvent;
FOnSwipeLeft : TSwipeEvent;
FOnSwipeUp : TSwipeEvent;
FOnSwipeDown : TSwipeEvent;
public
constructor Create(AOwner: TComponent); override;
destructor Destroy; override;
published
property OnSwipeRight: TSwipeEvent read FOnSwipeRight write FOnSwipeRight;
property OnSwipeLeft: TSwipeEvent read FOnSwipeLeft write FOnSwipeLeft;
property OnSwipeUp: TSwipeEvent read FOnSwipeUp write FOnSwipeUp;
property OnSwipeDown: TSwipeEvent read FOnSwipeDown write FOnSwipeDown;
end;

Enjoy!
