Is there a NSNotification for objects that become first resoponder?

Question

Is there a NSNotification for objects that become first responder. Like NSNotification that give me the UITextfield that cause the keyboard to pop up?

Answer 1

Check UITextFieldTextDidBeginEditingNotification, the textField that started editing is in notification's object property.

There're also UIKeyboardWillShowNotification and UIKeyboardDidShowNotification notifications

Answer 2

Another option is to have your view controller be a delegate to the UITextField. UITextFieldDelegate has a textFieldDidBeginEditing: method.

Answer 3

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.
