Is there a way to find out the height of the camera view only(not the picker view)? I need to know so I can centre the cross hairs on my overlay view vertically - screenshot below
As an option - you can create custom camera overlay view with all custom controls on positions you want and then set:
imagePickerController.cameraOverlayView = yourOverlayView;
imagePickerController.showsCameraControls = NO;
