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...")
}

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
}

简单实用的扩展:

extension UIView {
private struct OnClickHolder {
    static var _closure:()->() = {}
}

private var onClickClosure: () -> () {
    get { return OnClickHolder._closure }
    set { OnClickHolder._closure = newValue }
}

func onTap(closure: @escaping ()->()) {
    self.onClickClosure = closure
    
    isUserInteractionEnabled = true
    let tap = UITapGestureRecognizer(target: self, action: #selector(onClickAction))
    addGestureRecognizer(tap)
}

@objc private func onClickAction() {
    onClickClosure()
}

}

用法:

    override func viewDidLoad() {
    super.viewDidLoad()
    let view = UIView(frame: .init(x: 0, y: 0, width: 80, height: 50))
    view.backgroundColor  = .red
    view.onTap {
        print("View Tapped")
    }
}

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

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:));

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))
