Does the id type have enough information for the respondsToSelector method to work. I have a class with an ivar of type id, and when I invoke the respondsToSelector method it fails when it should succeed. I am assuming it should work fine, because if I skip checking with the respondsToSelector method and just make the call, it executes the method. Can someone please tell me what I am doing wrong?
What code are you using with -respondsToSelector: and to invoke the selector?
We need to see that in order to be able to say whether what you're doing will work.
On background: -respondsToSelector: is a message like any other message in Objective-C. It's not an operation on a type; you're actually sending a message to the object in question, which will use the Objective-C runtime to answer the question that's asked. So the static type of the variable referencing the object it's sent to -- in your case, "id" -- doesn't have anything to do with how the actual message behaves.
