objective c - Subclassing UIAlertController

Question

With pre-iOS 8 we had to use the UIAlertView and UIActionSheet

Which we weren't allowed to mess with the view hierarchy or subclass on either them.

UIAlertView Documentation

The UIAlertView class is intended to be used as-is and does not support subclassing. The view hierarchy for this class is private and must not be modified.

UIActionSheet Documentation

UIActionSheet is not designed to be subclassed, nor should you add views to its hierarchy. If you need to present a sheet with more customization than provided by the UIActionSheet API, you can create your own and present it modally with presentViewController:animated:completion:.

However with iOS8 Apple have introduced UIAlertController to replace both UIAlertView and UIActionSheet (Check the pre-release documentation here).

So in this pre-release documentation there is nothing about not being able to subclass or change the view heirarchy, it even has this method addTextFieldWithConfigurationHandler: so will we be able to change the view heirarchy and/or subclass UIAlertController without worrying whether Apple will approve or reject our applications?

Answer 1

It's a late response, but directly from Apple docs.

The UIAlertController class is intended to be used as-is and does not support subclassing. The view hierarchy for this class is private and must not be modified.

So, you shouldn't subclass UIAlertController.
