Answer 1

If you have set your UIWebView to an IBOutlet, you can do this in your viewDidLoad: method:

myWebView.delegate = self

Then, whenever anything happens in the web view, your delegate method in your view controller will be called.

Answer 2

First Step

@interface ViewController ()<UIWebViewDelegate>

@end

then set Delegate of your UIWebview to self

self..webview.delegate = self

then implement method you need

Answer 3

您可以为webview创建和IBOutlet，并可以像self.webview.delegate=self那样设置它的委托，也可以通过在UI Builder中单击并从UIWebview拖动到视图控制器上的Yellow图标来设置委托。
