        return NO;

    @end

Ok so im getting the yellow bug symbol on the lines:

    - (void)viewDidLoad
    {
      [super viewDidLoad];
        self.textField1.delegate = self;
        textField1.delegate = self;
    }

I don't know how to delegate all of my textFields? how do i make this textFieldReturn work for all of my textFields.. that viewDidLoad area has to be the problem, because everything else works good...
