首先，创建一个UITapGestureRecognizer对象

var tapGesture = UITapGestureRecognizer()

第二步是初始化UITapGestureReconizer。启用用户 交互，然后添加它。

override func viewDidLoad() {
        super.viewDidLoad()
    tapGesture = UITapGestureRecognizer(target: self, action: #selector(YourViewController.myviewTapped(_:)))
            infosView.isUserInteractionEnabled = true
            infosView.addGestureRecognizer(tapGesture)
view.addSubview(infosView)
}

第三，创建一个方法

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

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.

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)
}

我使用的是Xcode 7.3.1, Swift 2.2。见下文。

func addTapGesture() {
    let tap = UITapGestureRecognizer(target: self, action: #selector(MyViewController.handleTap))
    tap.numberOfTapsRequired = 1
    self.myView.addGestureRecognizer(tap)
}

func handleTap() {
    // Your code here...
}

如果你想要Objective - C代码，如下所示，

UITapGestureRecognizer *gesRecognizer = [[UITapGestureRecognizer alloc] initWithTarget:self action:@selector(handleTap:)]; // Declare the Gesture.
gesRecognizer.delegate = self;
[yourView addGestureRecognizer:gesRecognizer]; // Add Gesture to your view.

// Declare the Gesture Recognizer handler method.

- (void)handleTap:(UITapGestureRecognizer *)gestureRecognizer{
   NSLog(@"Tapped");
}

或者你想要swift代码如下所示，

import UIKit
class ViewController: UIViewController {

    @IBOutlet weak var myView: UIView!

    override func viewDidLoad() {
        super.viewDidLoad()

        // Add tap gesture recognizer to view
        let tapGesture = UITapGestureRecognizer(target: self, action: Selector("handleTap:"))
        myView.addGestureRecognizer(tapGesture)
    }

    // this method is called when a tap is recognized
    func handleTap(sender: UITapGestureRecognizer) {

        print("tap")
    }
}

以下是在Swift 5中添加手势视图的最简单方法

import UIKit

class ViewController: UIViewController {

    override func viewDidLoad() {
        super.viewDidLoad()
        addGestures()
    }

    // MARK: Add Gestures to target view
    func addGestures()
    {
        // 1. Single Tap or Touch
        let tapGesture = UITapGestureRecognizer(target: self, action: #selector(self.tapGetstureDetected))
        tapGesture.numberOfTapsRequired = 1
        view.addGestureRecognizer(tapGesture)

        //2. Double Tap
        let doubleTapGesture = UITapGestureRecognizer(target: self, action: #selector(self.doubleTapGestureDetected))
        doubleTapGesture.numberOfTapsRequired = 2
        view.addGestureRecognizer(doubleTapGesture)

        //3. Swipe
        let swipeGesture = UISwipeGestureRecognizer(target: self, action: #selector(self.swipeGetstureDetected))
        view.addGestureRecognizer(swipeGesture)

        //4. Pinch
        let pinchGesture = UIPinchGestureRecognizer(target: self, action: #selector(self.pinchGetstureDetected))
        view.addGestureRecognizer(pinchGesture)

        //5. Long Press
        let longPressGesture = UILongPressGestureRecognizer(target: self, action: #selector(self.longPressGetstureDetected))
        view.addGestureRecognizer(longPressGesture)

        //6. Pan
        let panGesture = UILongPressGestureRecognizer(target: self, action: #selector(self.panGestureDetected))
        view.addGestureRecognizer(panGesture)

    }

    // MARK: Handle Gesture detection
    @objc func swipeGetstureDetected() {
        print("Swipe Gesture detected!!")
    }

    @objc func tapGetstureDetected() {
        print("Touch/Tap Gesture detected!!")
    }

    @objc func pinchGetstureDetected() {
        print("Pinch Gesture detected!!")
    }

    @objc func longPressGetstureDetected() {
        print("Long Press Gesture detected!!")
    }

    @objc func doubleTapGestureDetected() {
        print("Double Tap Gesture detected!!")
    }

    @objc func panGestureDetected()
    {
        print("Pan Gesture detected!!")
    }


    //MARK: Shake Gesture
    override func becomeFirstResponder() -> Bool {
        return true
    }
    override func motionEnded(_ motion: UIEvent.EventSubtype, with event: UIEvent?){
        if motion == .motionShake
        {
            print("Shake Gesture Detected")
        }
    }
}
