Dynamically invoke a class method in Objective C

Suppose I have Objective C interface SomeClass which has a class method called someMethod:

@interface SomeClass : NSObject {
}

+ (id)someMethod;
@end

In some other interface I want to have a helper method that would dynamically invoke someMethod on a class like this:

[someOtherObject invokeSelector:@selector(someMethod) forClass:[SomeClass class];

What should be the implementation for invokeSelector? Is it possible at all?

- (void)invokeSelector:(SEL)aSelector forClass:(Class)aClass {
   // ???
}
