手势识别器不起作用。

执行下面元素的动作。

我将 UIView 添加到 TabBarController。

如果我点击创建的 UIView，它下面的元素的动作就会被执行。

class func createSpeechView(tabBar: UITabBarController)
    {

        let speech = Bundle.main.loadNibNamed("Speech", owner: Bundle.main, options: nil)![0] as! SpeechView

        tabBar.tabBar.addSubview(speech)
        speech.translatesAutoresizingMaskIntoConstraints = false

        speech.centerXAnchor.constraint(equalTo: tabBar.tabBar.centerXAnchor).isActive = true
        speech.topAnchor.constraint(equalTo: tabBar.tabBar.topAnchor, constant: -(height + 10)).isActive = true
        speech.widthAnchor.constraint(equalTo: tabBar.tabBar.widthAnchor, multiplier: 1.0, constant: -30).isActive = true
        speech.heightAnchor.constraint(equalToConstant: height).isActive = true

        speech.isUserInteractionEnabled = true
        speech.addGestureRecognizer(UIGestureRecognizer(target: tabBar, action: #selector(tapGesture)))

    }

    @objc class func tapGesture()
    {
        print("tap")
    }

【解决方案1】：

替换

speech.addGestureRecognizer(UIGestureRecognizer(target: tabBar, action: #selector(tapGesture)))

与

speech.addGestureRecognizer(UITapGestureRecognizer(target: tabBar, action: #selector(tapGesture)))
