Using `textField:shouldChangeCharactersInRange:`, how do I get the text including the current typed character?

Question

I\'m using the code below to try and have textField2\'s text content get updated to match textField1\'s whenever the user types in textField1

Answer 1

My solution is to use UITextFieldTextDidChangeNotification.

[[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(copyText:) name:UITextFieldTextDidChangeNotification object:nil];

Don't forget to call [[NSNotificationCenter defaultCenter] removeObserver:self]; in dealloc method.
