Finding out if a class is a subclass of another class (Objective-C)

Question

So I have a Class object, say for class 'D'. Is there a way to figure out if that class object is a subclass of another Class object, say 'B'? I tried -isKindOfClass: and isMemberOfClass, but neither worked. Thanks!

Answer 1

You should use class method +isSubclassOfClass.

Answer 2

Well hello there Grimless!

-isKindOfClass: should work fine, it says so in the documentation: http://developer.apple.com/library/mac/#/library/ios/documentation/Cocoa/Reference/Foundation/Protocols/NSObject_Protocol/Reference/NSObject.html

But there is another class method in NSObject called +isSubclassOfClass: that you should use instead.
