Discussion

Refer to a class only by its name when it is the receiver of a message. In all other cases, the class object must be obtained through this or a similar method. For example, here SomeClass is passed as an argument to the isKindOfClass: method (declared in the NSObject protocol):

BOOL test = [self isKindOfClass:[SomeClass class]];
