Ios TapGestureRecognitor在UIView子视图中不工作

我想将点击手势识别器添加到自定义UIView（表示图像和标签）。似乎手势识别器未添加到视图中，或者子视图未被视为UIView本身，因此无法工作

以下是我添加视图的方式：

• Navbar.swift：

（IconTextView是我的自定义视图）

然后，当我点击

indexButton

时，没有任何功能

我的点击功能，以防万一：

@objc func goToIndex(sender:UITapGestureRecognizer) {
        print("GO TO INDEX")
        router.setRoute(routeName: "INDEX", routeParam: "")
    }

---

我不明白为什么它不起作用，所有元素上都启用了用户交互。

您之前的代码+点击手势，我编辑约束，添加containerView：

class Aiutotipo: UIViewController {

let myImageView: UIImageView = {
    
    let iv = UIImageView()
    iv.contentMode = .scaleToFill
    iv.clipsToBounds = true
    iv.backgroundColor = .red
    iv.translatesAutoresizingMaskIntoConstraints = false
    
    return iv
}()

let myLabel: UILabel = {
    let label = UILabel()
    label.text = "Débats"
    label.textColor = .white
    label.textAlignment = .center
    label.font = .systemFont(ofSize: 30, weight: .semibold)
    label.translatesAutoresizingMaskIntoConstraints = false
    
    return label
}()

let containerView = UIView() //your container view

override func viewDidLoad() {
    super.viewDidLoad()
    
    containerView.backgroundColor = .red // red bacground for container view visible, set .clear for transparent bg
    containerView.isUserInteractionEnabled = true
    containerView.translatesAutoresizingMaskIntoConstraints = false
    
    let indexButtonTap = UITapGestureRecognizer(target: self, action: #selector(goToIndex))
    containerView.addGestureRecognizer(indexButtonTap)
    
    myImageView.image = UIImage(named: "profilo") // set here your image
    
    let myWidth = myLabel.intrinsicContentSize.width // This reveal only text width in label
    
    view.addSubview(containerView)
    containerView.heightAnchor.constraint(equalToConstant: myWidth + 50).isActive = true
    containerView.widthAnchor.constraint(equalToConstant: myWidth).isActive = true
    containerView.centerYAnchor.constraint(equalTo: view.centerYAnchor).isActive = true
    containerView.centerXAnchor.constraint(equalTo: view.centerXAnchor).isActive = true
    
    containerView.addSubview(myImageView)
    myImageView.topAnchor.constraint(equalTo: containerView.topAnchor).isActive = true
    myImageView.leadingAnchor.constraint(equalTo: containerView.leadingAnchor).isActive = true
    myImageView.trailingAnchor.constraint(equalTo: containerView.trailingAnchor).isActive = true
    myImageView.heightAnchor.constraint(equalTo: myImageView.widthAnchor).isActive = true
    
    containerView.addSubview(myLabel)
    myLabel.topAnchor.constraint(equalTo: myImageView.bottomAnchor).isActive = true
    myLabel.leadingAnchor.constraint(equalTo: containerView.leadingAnchor).isActive = true
    myLabel.trailingAnchor.constraint(equalTo: containerView.trailingAnchor).isActive = true
    myLabel.bottomAnchor.constraint(equalTo: containerView.bottomAnchor).isActive = true
}

@objc fileprivate func goToIndex() {
    print("GO TO INDEX")
 }
}

这就是结果

class Aiutotipo: UIViewController {

let myImageView: UIImageView = {
    
    let iv = UIImageView()
    iv.contentMode = .scaleToFill
    iv.clipsToBounds = true
    iv.backgroundColor = .red
    iv.translatesAutoresizingMaskIntoConstraints = false
    
    return iv
}()

let myLabel: UILabel = {
    let label = UILabel()
    label.text = "Débats"
    label.textColor = .white
    label.textAlignment = .center
    label.font = .systemFont(ofSize: 30, weight: .semibold)
    label.translatesAutoresizingMaskIntoConstraints = false
    
    return label
}()

let containerView = UIView() //your container view

override func viewDidLoad() {
    super.viewDidLoad()
    
    containerView.backgroundColor = .red // red bacground for container view visible, set .clear for transparent bg
    containerView.isUserInteractionEnabled = true
    containerView.translatesAutoresizingMaskIntoConstraints = false
    
    let indexButtonTap = UITapGestureRecognizer(target: self, action: #selector(goToIndex))
    containerView.addGestureRecognizer(indexButtonTap)
    
    myImageView.image = UIImage(named: "profilo") // set here your image
    
    let myWidth = myLabel.intrinsicContentSize.width // This reveal only text width in label
    
    view.addSubview(containerView)
    containerView.heightAnchor.constraint(equalToConstant: myWidth + 50).isActive = true
    containerView.widthAnchor.constraint(equalToConstant: myWidth).isActive = true
    containerView.centerYAnchor.constraint(equalTo: view.centerYAnchor).isActive = true
    containerView.centerXAnchor.constraint(equalTo: view.centerXAnchor).isActive = true
    
    containerView.addSubview(myImageView)
    myImageView.topAnchor.constraint(equalTo: containerView.topAnchor).isActive = true
    myImageView.leadingAnchor.constraint(equalTo: containerView.leadingAnchor).isActive = true
    myImageView.trailingAnchor.constraint(equalTo: containerView.trailingAnchor).isActive = true
    myImageView.heightAnchor.constraint(equalTo: myImageView.widthAnchor).isActive = true
    
    containerView.addSubview(myLabel)
    myLabel.topAnchor.constraint(equalTo: myImageView.bottomAnchor).isActive = true
    myLabel.leadingAnchor.constraint(equalTo: containerView.leadingAnchor).isActive = true
    myLabel.trailingAnchor.constraint(equalTo: containerView.trailingAnchor).isActive = true
    myLabel.bottomAnchor.constraint(equalTo: containerView.bottomAnchor).isActive = true
}

@objc fileprivate func goToIndex() {
    print("GO TO INDEX")
 }
}
