如果你有固定的视角，我建议你这样做

[self.view1 addGestureRecognizer:[[UITapGestureRecognizer alloc] initWithTarget:self action:@selector(tapTapTap:)]];
[self.view2 addGestureRecognizer:[[UITapGestureRecognizer alloc] initWithTarget:self action:@selector(tapTapTap:)]];

这样可以减少多个不同的无用变量

你可以用这段代码我的视图，也就是xib中的imageviews。

- (void)viewDidLoad
{
    firstIV.tag = 501;
    secondIV.tag = 502;
    thirdIV.tag = 503;
    forthIV.tag = 504;

    [self addTapGesturetoImageView: firstIV];
    [self addTapGesturetoImageView: secondIV];
    [self addTapGesturetoImageView: thirdIV];
    [self addTapGesturetoImageView: forthIV];
}

-(void)addTapGesturetoImageView:(UIImageView*)iv
{
    iv.userInteractionEnabled = YES;
    UITapGestureRecognizer * textfielBGIVTapGasture = [[UITapGestureRecognizer alloc] initWithTarget:self action:@selector(textfielBGIVTapped:)];
    textfielBGIVTapGasture.numberOfTapsRequired = 1;
    [iv addGestureRecognizer:textfielBGIVTapGasture];
}

- (void)textfielBGIVTapped:(UITapGestureRecognizer *)recognizer {
    int tag = recognizer.view.tag-500;
    switch (tag) {
        case 1:
        {
            //firstIV tapped;
            break;
        }
        case 2:
        {
            //secondIV tapped;
            break;
        }
        case 3:
        {
            //thirdIV tapped;
            break;
        }
        case 4:
        {
            //forthIV tapped;
            break;
        }
        default: {
            break;
        }
    }
}

我知道这是一个旧帖子，但我认为类似的东西，希望它对其他人有用。我简单地将我的imageViews存储在一个数组中，并将其分配给一个函数中的相同手势识别器来设置每个图像视图。

在我的viewDidLoad():

imageViewList = [imageView, imageView2, imageView3]
setupImageViews(imageViews: imageViewList)

设置图像视图的函数:

func setupImageViews(imageViews: [UIImageView]) {
    
    for imageView in imageViews {
        let tapGestureRecognizer = UITapGestureRecognizer(target: self, action: #selector(imageTapped(tapGestureRecognizer:)))
        imageView.isUserInteractionEnabled = true
        imageView.addGestureRecognizer(tapGestureRecognizer)
        
        //set up image to be displayed with the right aspect
        imageView.autoresizingMask = [.flexibleWidth, .flexibleHeight, .flexibleBottomMargin, .flexibleRightMargin, .flexibleLeftMargin, .flexibleTopMargin]
        imageView.contentMode = .scaleAspectFit // OR .scaleAspectFill
        imageView.clipsToBounds = true
    }
}

在动作选择器imagetapping()中，您可以为所选中的任何图像视图设置相应的代码。

@objc func imageTapped(tapGestureRecognizer: UITapGestureRecognizer)
{
    switch tapGestureRecognizer.view {
    case imageView:
        print("tapped Image View 1") //add your actions here
    case imageView2:
        print("tapped Image View 2") //add your actions here
    case imageView3:
        print("tapped Image View 3") //add your actions here
    default:
        print("Tap not detected")
    }
    _ = tapGestureRecognizer.view as! UIImageView
    //additional code...
}

我们可以做一些像这样的事情，这很简单

1)在控制器中创建如下函数(此函数将返回GestureRecognizer)

-(UITapGestureRecognizer*)setRecognizer{
     UITapGestureRecognizer *gestureRecognizer = [[UITapGestureRecognizer alloc] initWithTarget:self action:@selector(openProfile)];
     [gestureRecognizer setNumberOfTapsRequired:1];
     return gestureRecognizer;
}

2)现在在多个视图中设置这个识别器

[self.view1 addGestureRecognizer:[self setRecognizer]]; 
[self.view2 addGestureRecognizer:[self setRecognizer]];

好吧，如果有人不想代码添加手势视图的多个按钮像kwalker已经回答上面，并想通过接口生成器这样做，这可能会帮助你。

1)你可以从对象库中添加长按手势识别器，就像你添加其他对象，如UIButtons和UILabels。

最初我只用了一个

2)设置引用出口到UIButton和发送动作与文件的所有者。

注意:如果你有多个UIButton或任何其他对象，你将需要单独的手势识别器为他们每一个。详情请参考我的这个问题。长按手势识别器上的UIButton标签错误

您可以在视图上创建一个通用扩展来轻松地添加手势识别器。 这只是一个例子，但它可以是这样的

extension UIView {

    func setGestureRecognizer<Gesture: UIGestureRecognizer>(of type: Gesture.Type, target: Any, actionSelector: Selector, swipeDirection: UISwipeGestureRecognizer.Direction? = nil, numOfTaps: Int = 1) {
    let getRecognizer = type.init(target: target, action: actionSelector)

    switch getRecognizer {
    case let swipeGesture as UISwipeGestureRecognizer:
        guard let direction = swipeDirection else { return }
        swipeGesture.direction = direction
        self.addGestureRecognizer(swipeGesture)
    case let tapGesture as UITapGestureRecognizer:
        tapGesture.numberOfTapsRequired = numOfTaps
        self.addGestureRecognizer(tapGesture)
    default:
        self.addGestureRecognizer(getRecognizer)
    }
  }

}

要在视图上添加一个2点识别器，你只需调用:

let actionSelector = #selector(actionToExecute)
view.setGestureRecognizer(of: UITapGestureRecognizer.self, target: self, actionSelector: actionSelector, numOfTaps: 2)

您还可以轻松地添加一个滑动识别器

view.setGestureRecognizer(of: UISwipeGestureRecognizer.self, target: self, actionSelector: actionSelector, swipeDirection: .down)

等等。 只需要记住，目标必须链接到选择器。
