For the UIImagePickerController, if the allowsEditing flag is turned on, the view will move to Move and Scale view once the picture is taken. My question is, is there a way to detect the pushing of the shutter/capture button and then do something, before the Move and Scale view appears. There is no UIImagePickerController delegate available from what investigated.

technically you could perform an action when a picture is taken if you set your own overlay so that you can use your own button to do your action and call the take photo method from the uiimagepickercontroller.
Other than that you would have to use avfoundation.
