Expected identifer or ')' Objective C

Question

(IBAction)textFieldDoneEditing:(id)sender{//Expected identifer or ')'
    [sender resignFirstResponder];
}

What's wrong? It's an example from "Beginning iOS 6 Development"

Answer 1

Just do this:

-(IBAction)textFieldDoneEditing:(id)sender{//Expected identifer or ')'
    [sender resignFirstResponder];
}

You skipped the - at the beginning, that identifies that there's a method there.
