If you want to call a function while tapping a view you can use UITapGestureRecognizer

override func viewDidLoad() {
    super.viewDidLoad()
    let tapRecognizer = UITapGestureRecognizer(target: view, action: "handleSingleTap:")
    tapRecognizer.numberOfTapsRequired = 1
    self.view.addGestureRecognizer(tapRecognizer)
}

func handleSingleTap(recognizer: UITapGestureRecognizer) {
    //Do something here with the gesture
}

For Swift 3:

override func viewDidLoad() {
    super.viewDidLoad()
    let tapRecognizer = UITapGestureRecognizer(target: view, action: #selector(handleSingleTap))
    tapRecognizer.numberOfTapsRequired = 1
    self.view.addGestureRecognizer(tapRecognizer)
}

@objc func handleSingleTap(recognizer: UITapGestureRecognizer) {
    //Do something here with the gesture
}
