Hiding the Keyboard when losing focus on a UITextView

Question

So I have a UITextView that I\'m using to allow the user to submit some text.

My problem is, I can\'t seem to figure out how to allow the user to \'Cancel\' by tappi

Answer 1

override func touchesBegan(touches: NSSet, withEvent event: UIEvent) {
    var touch = event.allTouches()?.anyObject() as UITouch

    if( textfield.isFirstResponder() && touch.view != textfield) {
        textfield.resignFirstResponder()
        NSLog("Resigning first responder since touches began outside")
    }

    super.touchesBegan(touches, withEvent: event)
}

ohhorob's answer worked for me too. Here's the simple swift equivalent.
