I am trying to create an application that allows a user to take a picture from a camera device. I am using ImageCaptureCore.framework to do this by using the requestTakePicture method, and I've set a delegate to catch the didReceivePTPEvent message to tell me when the capture is complete.

If I try with my Canon PowerShot A80, didReceivePTPEvent is triggered, but when I use a Canon EOS Rebel T2i or any other professional camera device, didReceivePTPEvent is not triggered.

Does anyone know why didReceivePTPEvent is not triggered on some cameras?

Thanks for your help.
