swift - 如何向嵌套在 UIView 上的 RichTextView 添加手势识别器？

Question

我想将手势识别器添加到富 TextView 中，该 View 基本上是一个具有更多功能的 UIView，我将其放入名为“superiorView”的普通 UIView 中，我从 Cocoa Pods 下载了该包:

https://cocoapods.org/pods/RichTextView

我尝试了以下代码，但没有成功:

override func viewDidLoad(){

     super.viewDidLoad()


    let richTextView = RichTextView(
                        input: "hello",
                        latexParser: LatexParser(),
                        font: UIFont.systemFont(ofSize: UIFont.systemFontSize + 2),
                        textColor: UIColor.white,
                        isSelectable: false,
                        isEditable: false,
                        frame: CGRect(x: 0, y: 0, width: superiorView.frame.width, height: superiorView.frame.height),
                        completion: nil
                    )


    richTextView.isUserInteractionEnabled = true

            let tapgesture = UITapGestureRecognizer(target: self, action: #selector(self.clickLabel_1(_:)))
        tapgesture.numberOfTapsRequired = 1


            richTextView.addGestureRecognizer(tapgesture)


           superiorView.addSubview(richTextView)

}



@objc func clickLabel_1(_ sender:UIGestureRecognizer ){
        print("CLICKKKK 1 !")
    }

您正在配置手势识别器，但代码中没有将其添加到 richTextView:

    richTextView.addGestureRecognizer(tapgesture) // add gesture recognizer to text view.
