你需要用目标和动作初始化UITapGestureRecognizer，如下所示:

let tap = UITapGestureRecognizer(target: self, action: "handleTap:")
tap.delegate = self
myView.addGestureRecognizer(tap)

然后，你应该实现处理程序，它将在每次tap事件发生时被调用:

func handleTap(sender: UITapGestureRecognizer) {
  // handling code
}

内部ViewDidLoad

let tapGestureRecognizer = UITapGestureRecognizer(target: self, action: #selector(imageTapped(tapGestureRecognizer:)))
    self.imgMainAdView.isUserInteractionEnabled = true
    self.imgMainAdView.addGestureRecognizer(tapGestureRecognizer)

//MARK: - Image Tap Method -
@objc func imageTapped(tapGestureRecognizer: UITapGestureRecognizer)
{
    print("Tapped")
    if let url = URL(string: self.strMAinAdvLink)
    {
        UIApplication.shared.open(url, options: [:])
    }
}

打电话的目的

@IBAction func btnCall1Action(_ sender: Any)
{
    let text = self.strPhoneNumber1!
    let test = String(text.filter { !" -()".contains($0) })
    UIApplication.shared.openURL(NSURL(string: "tel://\(test)")! as URL)
}

邮件的目的

MFMailComposeViewControllerDelegate

 @IBAction func btnMailAction(_ sender: Any)
{
    let strEmail = SAFESTRING(str:  (self.dictEventDetails?.value(forKeyPath: "Email.value_text.email") as! String))

    if !MFMailComposeViewController.canSendMail()
    {
        AppDelegate.sharedInstance().showAlertAction(strTitle: "OK", strMessage: "Mail services are not available") { (success) in
        }
        return
    }
    let composeVC = MFMailComposeViewController()
    composeVC.mailComposeDelegate = self
    composeVC.setToRecipients([strEmail])
    composeVC.setSubject("")
    composeVC.setMessageBody("", isHTML: false)
    self.present(composeVC, animated: true, completion: nil)
}
func mailComposeController(_ controller: MFMailComposeViewController, didFinishWith result: MFMailComposeResult, error: Error?)
{
    controller.dismiss(animated: true, completion: nil)
}

我想指出两点，这两点一直给我带来麻烦。

I was creating the Gesture Recognizer on init and storing it in a let property. Apparently, adding this gesture recog to the view does not work. May be self object passed to the gesture recognizer during init, is not properly configured. The gesture recognizer should not be added to views with zero frames. I create all my views with zero frame and then resize them using autolayout. The gesture recognizers have to be added AFTER the views have been resized by the autolayout engine. So I add the gesture recognizer in viewDidAppear and they work.

Swift 4的完整答案

步骤1:为视图创建一个出口

@IBOutlet weak var rightViewOutlet: UIView!

步骤2:定义一个点击手势

var tapGesture = UITapGestureRecognizer()

步骤3:创建ObjC函数(当视图被点击时调用)

@objc func rightViewTapped(_ recognizer: UIGestureRecognizer) {
    print("Right button is tapped")
}

步骤4:在viewDidLoad()中添加以下内容

let rightTap = UITapGestureRecognizer(target: self, action: #selector(ViewController.rightViewTapped(_:)))
    rightViewOutlet.addGestureRecognizer(rightTap)

Swift 5.1三视图示例

步骤:1 ->添加storyboard视图和outlet viewController UIView

@IBOutlet var firstView: UIView!
@IBOutlet var secondView: UIView!
@IBOutlet var thirdView: UIView!

步骤:2 ->添加storyBoard视图标签

步骤:3 ->添加手势

override func viewDidLoad() {
        super.viewDidLoad()

        firstView.addGestureRecognizer(UITapGestureRecognizer(target: self, action: #selector(self.tap(_:))))
        firstView.isUserInteractionEnabled = true
        secondView.addGestureRecognizer(UITapGestureRecognizer(target: self, action: #selector(self.tap(_:))))
        secondView.isUserInteractionEnabled = true
        thirdView.addGestureRecognizer(UITapGestureRecognizer(target: self, action: #selector(self.tap(_:))))
        thirdView.isUserInteractionEnabled = true
    }

步骤:4 -> select view

@objc func tap(_ gestureRecognizer: UITapGestureRecognizer) {
        let tag = gestureRecognizer.view?.tag
        switch tag! {
        case 1 :
            print("select first view")
        case 2 :
            print("select second view")
        case 3 :
            print("select third view")
        default:
            print("default")
        }
    }
