UIImagePickerController with camera source with allows editing yes : video trimming doesn't work
allowsEditing : A Boolean value indicating whether the user is allowed to edit a selected still image or movie.
@property (nonatomic) BOOL allowsEditing
DiscussionIf you allow the user to edit still images or movies, the delegate may receive a dictionary with information about the edits that were made. The protocol for the delegate is described in UIImagePickerControllerDelegate Protocol Reference.
I Think this will be helpful.
you need to grab the info[UIImagePickerControllerEditedImage] from the - (void)imagePickerController:(UIImagePickerController *)picker didFinishPickingMediaWithInfo:(NSDictionary *)info
I believe.
