If your intent is to check to see if the UIRefreshControl class exists at runtime, then do this instead: if (NSClassFromString(@"UIRefreshControl")) The line you wrote above checks to see if the method "setRefreshControl" exists inside the method's own class. I doubt that's your intention, especially since set-methods typically take an argument, and if the method takes an argument, then you would need to use "setRefreshControl:" instead.
