基于已接受的答案，你可以定义一个宏:

#define handle_tap(view, delegate, selector) do {\
    view.userInteractionEnabled = YES;\
    [view addGestureRecognizer: [[UITapGestureRecognizer alloc] initWithTarget:delegate action:selector]];\
} while(0)

这个宏使用ARC，所以没有发布调用。

宏使用示例:

handle_tap(userpic, self, @selector(onTapUserpic:));

你可以通过在代码中添加手势识别器来实现这一点。

步骤1:ViewController.m:

// Declare the Gesture.
UITapGestureRecognizer *gesRecognizer = [[UITapGestureRecognizer alloc] 
                                          initWithTarget:self 
                                          action:@selector(handleTap:)];
gesRecognizer.delegate = self;

// Add Gesture to your view.
[yourView addGestureRecognizer:gesRecognizer]; 

步骤2:ViewController.m:

// Declare the Gesture Recogniser handler method.
- (void)handleTap:(UITapGestureRecognizer *)gestureRecognizer{
   NSLog(@"Tapped");
}

注意:这里的yourView在我的情况是@property(强，非原子)IBOutlet UIView *localView;

编辑:*localView是Main中的白色框。下面的故事板

手势识别器

有许多常用的触摸事件(或手势)，当你添加一个手势识别器到你的视图时，你可以得到通知。默认支持以下手势类型:

UITapGestureRecognizer轻触(简单触摸屏幕一次或多次) UILongPressGestureRecognizer长触(长时间触屏) UIPanGestureRecognizer Pan(在屏幕上移动手指) 滑动(快速移动手指) UIPinchGestureRecognizer捏(将两个手指放在一起或分开-通常是缩放) UIRotationGestureRecognizer旋转(沿圆周方向移动两个手指)

除此之外，你还可以制作自己的手势识别器。

在接口生成器中添加一个手势

将一个手势识别器从对象库拖到视图上。

控件从文档大纲中的手势拖到视图控制器代码中，以创建Outlet和Action。

这应该在默认情况下设置，但也要确保为视图将User Action Enabled设置为true。

以编程方式添加手势

要以编程方式添加一个手势，你(1)创建一个手势识别器，(2)将它添加到视图中，(3)创建一个方法，当手势被识别时调用该方法。

import UIKit
class ViewController: UIViewController {

    @IBOutlet weak var myView: UIView!
    
    override func viewDidLoad() {
        super.viewDidLoad()
        
        // 1. create a gesture recognizer (tap gesture)
        let tapGesture = UITapGestureRecognizer(target: self, action: #selector(handleTap(sender:)))
        
        // 2. add the gesture recognizer to a view
        myView.addGestureRecognizer(tapGesture)
    }
    
    // 3. this method is called when a tap is recognized
    @objc func handleTap(sender: UITapGestureRecognizer) {
        print("tap")
    }
}

笔记

sender参数为可选参数。如果你不需要一个手势的引用，那么你可以把它去掉。如果你这样做，但是，删除(sender:)后的动作方法名称。 handleTap方法的命名是任意的。使用action: #selector(someMethodName(sender:))将其命名为任何您想要的名称。

更多的例子

您可以研究我添加到这些视图中的手势识别器，以了解它们是如何工作的。

下面是该项目的代码:

import UIKit
class ViewController: UIViewController {
    
    @IBOutlet weak var tapView: UIView!
    @IBOutlet weak var doubleTapView: UIView!
    @IBOutlet weak var longPressView: UIView!
    @IBOutlet weak var panView: UIView!
    @IBOutlet weak var swipeView: UIView!
    @IBOutlet weak var pinchView: UIView!
    @IBOutlet weak var rotateView: UIView!
    @IBOutlet weak var label: UILabel!
    
    override func viewDidLoad() {
        super.viewDidLoad()
        
        // Tap
        let tapGesture = UITapGestureRecognizer(target: self, action: #selector(handleTap))
        tapView.addGestureRecognizer(tapGesture)
        
        // Double Tap
        let doubleTapGesture = UITapGestureRecognizer(target: self, action: #selector(handleDoubleTap))
        doubleTapGesture.numberOfTapsRequired = 2
        doubleTapView.addGestureRecognizer(doubleTapGesture)
        
        // Long Press
        let longPressGesture = UILongPressGestureRecognizer(target: self, action: #selector(handleLongPress(gesture:)))
        longPressView.addGestureRecognizer(longPressGesture)
        
        // Pan
        let panGesture = UIPanGestureRecognizer(target: self, action: #selector(handlePan(gesture:)))
        panView.addGestureRecognizer(panGesture)
        
        // Swipe (right and left)
        let swipeRightGesture = UISwipeGestureRecognizer(target: self, action: #selector(handleSwipe(gesture:)))
        let swipeLeftGesture = UISwipeGestureRecognizer(target: self, action: #selector(handleSwipe(gesture:)))
        swipeRightGesture.direction = UISwipeGestureRecognizerDirection.right
        swipeLeftGesture.direction = UISwipeGestureRecognizerDirection.left
        swipeView.addGestureRecognizer(swipeRightGesture)
        swipeView.addGestureRecognizer(swipeLeftGesture)
        
        // Pinch
        let pinchGesture = UIPinchGestureRecognizer(target: self, action: #selector(handlePinch(gesture:)))
        pinchView.addGestureRecognizer(pinchGesture)
        
        // Rotate
        let rotateGesture = UIRotationGestureRecognizer(target: self, action: #selector(handleRotate(gesture:)))
        rotateView.addGestureRecognizer(rotateGesture)
        
    }
    
    // Tap action

        label.text = "Tap recognized"

            let alert = UIAlertController(title: "Long Press", message: "Can I help you?", preferredStyle: UIAlertControllerStyle.alert)
            alert.addAction(UIAlertAction(title: "OK", style: UIAlertActionStyle.default, handler: nil))

        }
    }

        panView.center = location
    }

        if gesture.direction == UISwipeGestureRecognizerDirection.right {
            UIView.animate(withDuration: 0.5, animations: {
                self.swipeView.center.x += self.view.bounds.width
            }, completion: { (value: Bool) in

            })
        } else if gesture.direction == UISwipeGestureRecognizerDirection.left {
            UIView.animate(withDuration: 0.5, animations: {
                self.swipeView.center.x -= self.view.bounds.width
            }, completion: { (value: Bool) in
                self.swipeView.center = originalLocation
            })

    @objc func handlePinch(gesture: UIPinchGestureRecognizer) {
        label.text = "Pinch recognized"
        
        if gesture.state == UIGestureRecognizerState.changed {
            let transform = CGAffineTransform(scaleX: gesture.scale, y: gesture.scale)
            pinchView.transform = transform
        }
    }

            rotateView.transform = transform
        }
    }

笔记

You can add multiple gesture recognizers to a single view. For the sake of simplicity, though, I didn't do that (except for the swipe gesture). If you need to for your project, you should read the gesture recognizer documentation. It is fairly understandable and helpful. Known issues with my examples above: (1) Pan view resets its frame on next gesture event. (2) Swipe view comes from the wrong direction on the first swipe. (These bugs in my examples should not affect your understanding of how Gestures Recognizers work, though.)

斯威夫特和斯威夫特

import UIKit

extension UIView {
  func addTapGesture(tapNumber: Int, target: Any, action: Selector) {
    let tap = UITapGestureRecognizer(target: target, action: action)
    tap.numberOfTapsRequired = tapNumber
    addGestureRecognizer(tap)
    isUserInteractionEnabled = true
  }
}

Use

yourView.addTapGesture(tapNumber: 1, target: self, action: #selector(yourMethod))

在iOS 3.2及更高版本中，你可以使用手势识别器。例如，这是你处理点击事件的方式:

//The setup code (in viewDidLoad in your view controller)
UITapGestureRecognizer *singleFingerTap = 
  [[UITapGestureRecognizer alloc] initWithTarget:self 
                                          action:@selector(handleSingleTap:)];
[self.view addGestureRecognizer:singleFingerTap];

//The event handling method
- (void)handleSingleTap:(UITapGestureRecognizer *)recognizer
{
  CGPoint location = [recognizer locationInView:[recognizer.view superview]];

  //Do stuff here...
}

还有一些内置的手势。查看iOS事件处理和UIGestureRecognizer的文档。我还在github上有一堆示例代码，可能会有所帮助。

我认为你可以简单地使用

UIControl *headerView = ...
[headerView addTarget:self action:@selector(myEvent:) forControlEvents:UIControlEventTouchDown];

我的意思是headerView从UIControl扩展过来。
