Swift UITextFieldShouldReturn Return Key Tap

Question

(iOS8, Xcode6, Swift) Using Swift, how do I capture a tap on the \"Return\" button?

The doc at the following link specifies using the textFieldShouldReturn

Answer 1

You need to set an object as the text field's delegate. Usually that would be the view controller that the text field exists in. You don't need to inherit from any other class, or, strictly speaking, implement a delegate (but you could implement UITextFieldDelegate to make things a little clearer.)
