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:));

创建一个手势识别器(子类)，它将实现触摸事件，如touchesBegan。之后可以将其添加到视图中。

这样您将使用组合而不是子类化(这是请求)。

以下是Swift版本:

// MARK: Gesture Extensions
extension UIView {

    func addTapGesture(#tapNumber: Int, target: AnyObject, action: Selector) {
        let tap = UITapGestureRecognizer (target: target, action: action)
        tap.numberOfTapsRequired = tapNumber
        addGestureRecognizer(tap)
        userInteractionEnabled = true
    }

    func addTapGesture(#tapNumber: Int, action: ((UITapGestureRecognizer)->())?) {
        let tap = BlockTap (tapCount: tapNumber, fingerCount: 1, action: action)
        addGestureRecognizer(tap)
        userInteractionEnabled = true
    }
}

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

斯威夫特5.3

基于闭包的UIGestureRecognizer解决方案

final class BindableGestureRecognizer: UITapGestureRecognizer {
    private var action: () -> Void

    init(action: @escaping () -> Void) {
        self.action = action
        super.init(target: nil, action: nil)
        self.addTarget(self, action: #selector(execute))
    }

    @objc private func execute() {
        action()
    }
}

public extension UIView {
    /// A discrete gesture recognizer that interprets single or multiple taps.
    /// - Parameters:
    ///   - tapNumber: The number of taps necessary for gesture recognition.
    ///   - closure: A selector that identifies the method implemented by the target to handle the gesture recognized by the receiver. The action selector must conform to the signature described in the class overview. NULL is not a valid value.
    func addTapGesture(tapNumber: Int = 1, _ closure: (() -> Void)?) {
        guard let closure = closure else { return }

        let tap = BindableGestureRecognizer(action: closure)
        tap.numberOfTapsRequired = tapNumber
        addGestureRecognizer(tap)

        isUserInteractionEnabled = true
    }
}

使用:

view.addTapGesture { [weak self] in
    self?.view.backgroundColor = .red
}

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。
