Question

I’m looking for a complete list of classes that support the UIAppearance protocol. I have not been able to find one. I’m open to suggestions for how to programmatically generate such a list (which I have given a tiny bit of thought to already).

Answer 1

This is not a definitive or complete list, but of course minutes after posting the question (by following a link to this related question), I find this weblink:

http://blog.mosheberman.com/list-of-classes-that-support-uiappearance-in-ios-5/

There the poster used a grep command (grep -r UI_APPEARANCE_SELECTOR ./ > ~/Desktop/UI_APPEARANCE.txt) to dump out all the classes that have UI_APPEARANCE_SELECTOR in a method prototype. The list they came up with is as follows:

• UIActivityIndicatorView.h
• UIBarButtonItem.h
• UIBarItem.h
• UINavigationBar.h
• UIProgressView.h
• UISearchBar.h
• UISegmentedControl.h
• UISlider.h
• UISwitch.h
• UITabBar.h
• UITabBarItem.h
• UIToolbar.h

Of course, this doesn’t include classes that subclass those listed above. Also, the poster mentions UIView, which definitely implements the protocol, but doesn’t have any methods marked with UI_APPEARANCE_SELECTOR. I wonder if a more complete list could be created by grepping for UIAppearance.
