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)



  1. NICE!

    This is a big deal... these components are crucial for the iOS experience and "feel" (the look still needs some work on our side, but I bet that next updates will come with improvements on this).

    Very nice work, will test it ASAP. That will be very nice on MathWiz! :)

  2. @Olecramoak: MathViz 1.1 has been submitted. 1.2 will probably be the one to have the keyboard. Just testing update mechanism for now. We'll see in 6 days... ;)

  3. @Anders: just submitted an update yesterday myself. This waiting is just stressful. Hope the folks over there are in a good mood.

  4. Hi Anders,

    Nice for this comps ! Thanks, And good luck for your Mathwiz !

    I have, for my own projet, make work surround multitouch on IOS, in order to enable it for XE2.

    I have done a step by step : Have you see it ? Perhaps, you can advise me on a better way to do it.

    Beyond that, I will be in the SF area next week, are you in place ?
    Mail me please !

  5. You are great man! I m waiting web service component too :)

  6. Thanks, that is great progress!
    How is the Zoom/Pinch event supposed to work?
    The OnZoom event has just a scale factor as a parameter.
    I would expect to get in addition at least the current center of gravity position in X, Y values to zoom the right portion of the graphics.

  7. Hi,

    Agreed, great progress. :)

    I Add to the request : The UIPinchGestureRecognizer class include the velocity property : Why not included it ?

    @Thomas : In waiting the Anders solution, my add to your request :
    This class does not include coord (i.e. "gravity"), but you can access it via multitouch...

  8. @Vincent: Thanks! I have not tried enabling multi-touch yet. I haven't needed it so far... ;) I'll check it out.

    @Emrah: I haven't looked at that either yet... ;)

    @Thomas: I didn't think through it that far... I only needed scale to get scaling working... And I only have one thing to zoom at the moment.

    @Vincent: Thanks! Yep. You're right. I didn't add it because I didn't need it. If you need it, by all means add it. I'll probably add it soon. These are after all created as I play around and use them... ;)

  9. If i may suggest something: there are 2 very important example that should have been included with Firemonkey for iOS: iAd support and in Game Purchase. If anyone has some example that would be great for the delphi community!

  10. @Xavier: Cool!

One such add on that women, specially young girls love to have are jackets, trendy and stylish ones are always in fashion they never go out of fashion and can be clubbed with any kind of dress, you can wear a jacket (In Swedish jackor) over a short skirt also and club one with your denims also, any thing looks good, in fact they give a complete look to whatever one wears.

  14. Hi! I'm Odden. We’ve worked out that bespoke languages tuition are a global operation, but do they provide genuinely excellent Spanish tutoring and French tutoring? Their site is superb, but does that reflect the quality of their tutoring? Opinions gratefully received!

  15. Hi! I'm Angelini. We've been told that bespoke languages tuition are endorsed by Princeton University to provide French tutoring, German tuition and Spanish tuition across the globe? Can someone cast some light on this? Also, how can their 11 Plus tuition be endorsed by Oxford University too?

  16. Hi! I'm Mouldin. I know bespoke languages tuition are global, but is their Spanish tuition or French tuition really as good as they say?
