多个WKWebView实例的独立webView didFinish WKNavigationDelegate方法

WKNavigationDelegate 或者任何协议的方法只能在每个类中继承一次,但您可以很容易地找出委托方法是从哪个实例调用的,如下所示:

class YourClass: WKNavigationDelegate {

    var webView1: WKWebView!
    var webView2: WKWebView!

    func webView(_ webView: WKWebView, didFinish navigation: WKNavigation!) {
        if (webView == self.webView1) {
            print("didFinishNavigationWebView1")
        } else if (webView == self.webView2) {
            print("didFinishNavigationWebView2")
        }
    }

}
