objective c - Can't build in Xcode 4.5 because of "Multiple methods named" error

Question

I'm having problems with building my project in Xcode 4.5. Xcode gives me this error "Multiple methods named 'item' found with mismatched result, parameter type or attributes". Can someone tell me what the problem is? how to resolve multiple methods names error?

Answer 1

You probably have different classes implementing the method item but returning a different type of result. If you then try to invoke item on an id typed pointer, there's no way to know what the result type is supposed to be.

That's what XCode is lamenting about.

How to solve it depends a lot on what are you really are trying to do. Probably using different names for the methods is the best solution.
