Just as a minor nit, it's probably better to write [[MyClass superclass] instancesRespondToSelector:...]. This variant will survive if you re-target your superclass and forget to change what it depends on. Both variants will still fail if you subject your code to copypasta without sufficient vetting. If you're adventurous and foolish you can extract your superclass without needing to hard-code any class names: #import <objc/objc-runtime.h> ... Class superclass = ((struct objc_super *)super)->class; But this is probably a poor idea to use in practice....
