Getting the Value of a UITextField as keystrokes are entered?

Question

Let\'s say I have the following code:

IBOutlet UITextField* nameTextField;
IBOutlet UILabel* greetingLabel;

I\'d like the greetingLab

Answer 1

UITextField has a notification UITextFieldTextDidChange which will be fired every time the text changes if you register for it. Just register for that notification and in the method called by the notification, change the label's text.

To add to this, the object passed to your notification handler will have the text of the UITextField.

Hope that helps.
