另一种方法是向视图添加一个透明按钮

UIButton *b = [UIButton buttonWithType:UIButtonTypeCustom];
b.frame = CGRectMake(0, 0, headerView.width, headerView.height);
[headerView addSubview:b];
[b addTarget:self action:@selector(buttonClicked:) forControlEvents:UIControlEventTouchDown];

然后，handle click:

- (void)buttonClicked:(id)sender
{}

objective - c:

UIControl *headerView = [[UIControl alloc] initWithFrame:CGRectMake(0, 0, tableView.bounds.size.width, nextY)];
[headerView addTarget:self action:@selector(myEvent:) forControlEvents:UIControlEventTouchDown];

迅速:

let headerView = UIControl(frame: CGRect(x: 0, y: 0, width: tableView.bounds.size.width, height: nextY))
headerView.addTarget(self, action: #selector(myEvent(_:)), for: .touchDown)

问题是:

我如何添加一个触摸事件到一个UIView?

它并不是在请求一个点击事件。

特别是OP想要实现UIControlEventTouchDown

切换UIView到UIControl是正确的答案，因为手势识别器不知道。touchdown。touchupinside，。touchupoutside等等。

此外，UIControl继承自UIView，所以你不会失去任何功能。

如果你想要的只是轻敲一下，那么你可以使用手势识别器。但如果你想要更好的控制，就像这个问题要求的，你需要UIControl。

https://developer.apple.com/documentation/uikit/uicontrol?language=objc https://developer.apple.com/documentation/uikit/uigesturerecognizer?language=objc

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。

你们为什么不试试ssevenlistener呢?

您不需要创建任何手势识别器，并将您的逻辑分离到另一个方法。ssevenlistener支持在视图上设置侦听器块，以侦听单个点击手势，双击手势和N-tap手势，如果你喜欢，和长按手势。设置一个点击手势监听器是这样的:

[view ss_addTapViewEventListener:^(UITapGestureRecognizer *recognizer){…} numberOfTapsRequired: 1);

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。

在Swift 4.2和Xcode 10中

使用UITapGestureRecognizer for添加触摸事件

//Add tap gesture to your view
let tap = UITapGestureRecognizer(target: self, action: #selector(handleGesture))
yourView.addGestureRecognizer(tap)

// GestureRecognizer
@objc func handleGesture(gesture: UITapGestureRecognizer) -> Void {
//Write your code here
}

如果你想使用SharedClass

//This is my shared class
import UIKit

class SharedClass: NSObject {

    static let sharedInstance = SharedClass()

    //Tap gesture function
    func addTapGesture(view: UIView, target: Any, action: Selector) {
        let tap = UITapGestureRecognizer(target: target, action: action)
        view.addGestureRecognizer(tap)
    }
} 

我的ViewController中有3个视图，分别是view1 view2和view3。

override func viewDidLoad() {
    super.viewDidLoad()
    //Add gestures to your views
    SharedClass.sharedInstance.addTapGesture(view: view1, target: self, action: #selector(handleGesture))
    SharedClass.sharedInstance.addTapGesture(view: view2, target: self, action: #selector(handleGesture))
    SharedClass.sharedInstance.addTapGesture(view: view3, target: self, action: #selector(handleGesture2))

}

// GestureRecognizer
@objc func handleGesture(gesture: UITapGestureRecognizer) -> Void {
    print("printed 1&2...")
}
// GestureRecognizer
@objc func handleGesture2(gesture: UITapGestureRecognizer) -> Void {
    print("printed3...")
}
