Question

When passing a delegate to MyClass like this,

- (MyClass *)initWithDelegate:(id <MyDelegate>)delegate {..}

is it somehow possible to tell what kind of class my delegate is? Being defined as id, delegate doesn’t seem to respond to any method calls like class, description, respondsToSelector etc.

I’d like to be able to track who is calling MyClass!

Thanks in advance!

Answer 1

You can call [delegate class]; to get the class of the delegate.

If delegate doesn’t respond to that, that means it is nil.

Edit

Now that you mention that you get compiler errors, then your delegate doesn’t conform to the protocol NSObject. So the compiler doesn’t recognize it as an NSObject. You should modify the declaration of your protocol MyDelegate to the following:

@protocol MyDelegate <NSObject>

// ...
