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.

Answer 2

You are missing a minus in front of your declaration:

-(IBAction)textFieldDoneEditing:(id)sender {
    [sender resignFirstResponder];
}

It is not optional - a minus (for the instance methods) or a plus (for the class methods) is required by Objective C syntax.
