The easy answer is you’re not supposed to do it because it’s fragile and guaranteed to break. You’re also not supposed to have to do it. I wish I could ever remember how compatibility is meant to work. If you build for minimum target 7 but run on 8, isn’t the API your code ‘sees’ supposed to be ‘compatible with 7’ or is it allowed to give you a UIKeyboardWillChangeFrameNotification which looks like iOS8? That could just be a bug. _______________________________________________ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.
