static method NSInvocation

Question

Is it possible to use NSInvocation for static method calls?

We're using NSInvocation to simplify our method calls in unit tests for non-public methods.

This works great for our instance methods, for which we provide an object and appropriate data to NSInvocation. However, can we do the same with static methods?

Answer 1

Yes, you can. Assuming your class is MyClass and your method is +(void)myClassMethod:(id)sender; , you can use:

NSMethodSignature *signature = [MyClass methodSignatureForSelector:@selector(myClassMethod:)];

Then you can provide the NSMethodSignature to your NSInvocation when created:

NSInvocation *invocation = [NSInvocation invocationWithMethodSignature:signature];
