Objective-C Runtime: best way to check if class conforms to protocol?

Question

I have a Class (but no instance) and need to know if it conforms to a certain protocol. However, Class can be subclassed several times and class_conformsToProtocol() ignores

Answer 1

Or, in case it is a general pointer, like:

Class<MyProtocol> someClassPointer = nil;

you can use:

[someClassPointer.class conformsToProtocol:@protocol(MyProtocol)];

Answer 2

According to the docs,

[MyClass conformsToProtocol:@protocol(MyProtocol)];

should work.
