Question

I have been working around in UIImagePickerController and am struck with a problem where I need to get the precise moment when the camera shutter opens in UIImagePickerController when the source type is set to camera (UIImagePickerControllerSourceTypeCamera).

I have done some googling around and have realized that no one had such strange requirement!

I looked around the docs of UIImagePickerController and UIImagePickerControllerDelegate hoping to get some delegate method / callback indicating the camera shutter open event, but did not find any.

Any suggestions?

Thanks for any help,

The solution is to observe for a private notification, just as discussed in this thread:
