Is there a NSNotification for objects that become first responder.
Like NSNotification that give me the UITextfield that cause the keyboard to pop up?
UITextFieldTextDidBeginEditingNotification, the textField that started editing is in notification's
Another option is to have your view controller be a delegate to the UITextField. UITextFieldDelegate has a textFieldDidBeginEditing: method.
No, But you could check it manually by using "IsFirstResponder" (BOOL).. Can you explain a little bit more what you want to accomplish? Maybe there is a way to use another notification.
