Is anyone able to provide a definitive guide to the labelled icons in Xcode 4's debug area variable list? Here's a list of what I have at the moment.

I haven't been able to find a list of what these icons mean, either in Xcode's documentation, or online. Thank-you, Steve. I haven't been able to find a guide for these values, but they appear to be: L = Local variable A = Argument S = Static variable V = global Variable R = register V = instance Variable E =

I created a Text Field in Interface Builder. I set it's "Return Key" to Done. This is a one line only input (so it wont need multiple lines). How do I hide the virtual keyboard when the user taps the done button? Paul Hunter Implement the delegate method UITextFieldDelegate , then: - (void)viewDidLoad { [super viewDidLoad]; self.yourIBtextField.delegate = self; } - (BOOL)textFieldShouldReturn:(UITextField *)textField { [textField resignFirstResponder]; return NO; } UITextView does not have any methods which will be called when the user hits the return key. Even then if you want to do this,
