ios - WebView 与触摸事件 UITapGestureRecognizer 无法识别的选择器

Question

当我运行我的代码时，这个错误总是发生。您能告诉我问题出在哪里以及如何在 Swift 3 中修复它吗？

错误:

[UIWebView tapAction:]: unrecognized selector sent to instance 0x7f9bfbf14e60

代码:

class ViewController: UIViewController, UITextFieldDelegate, UIGestureRecognizerDelegate {

    @IBOutlet var webView: UIWebView!

    override func viewDidLoad() {
        super.viewDidLoad()
        // Do any additional setup after loading the view, typically from a nib.  
        let url = URL(string: "http://www.pdf995.com/samples/pdf.pdf")!
        webView.loadRequest(URLRequest(url: url))

        let webViewTapped = UITapGestureRecognizer(target: webView, action: #selector(self.tapAction(_:)))
        webViewTapped.numberOfTouchesRequired = 1
        webViewTapped.delegate = self
        webView.addGestureRecognizer(webViewTapped)
   }

   func tapAction(_ sender: UITapGestureRecognizer) {
       let point = sender.location(in: self.view)
       print("123")
       print(point.x)
       print(point.y)
   }

从 webView 更改目标:

let webViewTapped = UITapGestureRecognizer(target: webView, action: #selector(self.tapAction(_:)))

致自己:

let webViewTapped = UITapGestureRecognizer(target: self, action: #selector(self.tapAction(_:)))
