How can I get a textDidChange (like for a UISearchBar) method for a UITextField?

Question

How can I get a textDidChange method for a UITextField? I need to call a method every time a change is made to a text field. Is this possible? Thanks!

You can use the UITextFieldTextDidChangeNotification to call a method whenever the text field changes. Add this to your init:

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