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

Implement this function

func textFieldShouldReturn(_ textField: UITextField) -> Bool {   //delegate method
   textField.resignFirstResponder()
   return true
}

And for delegate you can set using the Utilities pane / Connections Inspector / delegate and then drag to ViewController (yellow button in the storyboard)

Then you do not need to set the delegate programmatically for every text field
