I’m trying to check for the availability of the UIAppearance class using:
NSClassFromString(@"UIAppearance")
However this returns nil from both iOS4 and iOS5 – anyone got any tips on how to work around this?
UIAppearance is not a class, it is a protocol. So in order to check wether it exists or not, you would use:
It returns null on < iOS5, but an object on iOS5.
