xcode - How do I get the return key to perform the same action as a button press in Swift?

Question

I want to know how you allow an action to be made by either pressing the return key on the software keyboard or by tapping a UIButton.

The UI button is already set up to perform an IBAction.

How do I also allow users to press the return key on the keyboard to perform the same action?

Answer 1

Make sure your class extends the UITextFieldDelegate protocol

SomeViewControllerClass : UIViewController, UITextFieldDelegate

You can perform action as follows:

override func viewDidLoad() {
    super.viewDidLoad()

    self.textField.delegate = self
}

func textFieldShouldReturn(textField: UITextField) -> Bool {

    //textField code

    textField.resignFirstResponder()  //if desired
    performAction()
    return true
}

func performAction() {   
    //action events
}
