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")
    }
}

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...
}

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")
        }
    }

    let tap = UITapGestureRecognizer(target: self, action: Selector("handleFrontTap:"))
    frontView.addGestureRecognizer(tap)

// Make sure this is not private
func handleFrontTap(gestureRecognizer: UITapGestureRecognizer) {
    print("tap working")
}

我是在swift上的Xcode 6.4上完成的。见下文。

var view1: UIView!

func assignTapToView1() {          
  let tap = UITapGestureRecognizer(target: self, action: Selector("handleTap"))
  //  tap.delegate = self
  view1.addGestureRecognizer(tap)
  self.view .addSubview(view1)

...
}

func handleTap() {
 print("tap working")
 view1.removeFromSuperview()
 // view1.alpha = 0.1
}

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)
