What does “conform to” means in IPhone Development? This word is extensively used but I can’t find a satisfactory definition of it.
Let’s say If we have 3 classes – A,B & C
If A inherits B
&
If A conforms to C
What does that means?
Also, Why does most classes,protocols conforms to NSObject.
In your example, C would have to be a protocol. Protocols are just a lists of method signatures.
If A conforms to C, it means it implements all the methods listed in the protocol (ie method bodies are provided for each of the method signatures defined in the protocol.)
Since A also inherits from B, A does does not have to explicitly implement methods that B has already implemented.
