My app uses the camera, and I added the zoom function thanks to 3.1 API (cameraViewTransform most importantly). But I want my app to run also on 3.0 (without the zoom of course). The problem is that, I cannot compile the app in 3.0 due to this line which calls 3.1 properties:
CGAffineTransform initialTransform = photoPicker.cameraViewTransform;
If it was a method then I could have used performSelector or something like that. Changing it to initialTransform = [photoPicker cameraViewTransform] doesn't work neither. Is there any solution for this?
I think this question is similar to yours, maybe the solution there might help you.
