推荐答案

除了DBD提供的答案，你还需要确保

In addition to the answer provided by DBD, you will need to ensure that

1. 包含的 UIViewController 在 .h 文件中被标记为 UIWebViewDelegate:

1. The containing UIViewController is marked as a UIWebViewDelegate in the .h file:

@interface VIMAuthenticationViewController : UIViewController <UIWebViewDelegate>

UIWebView 的委托设置为包含 UIViewController.这可以直接在 Interface Building 中完成，也可以通过链接 Web 视图并在 .m fie 中加载的视图中添加以下内容:

The UIWebView's delegate is set to the containing UIViewController. This can be done directly in the Interface Building or by linking the web view and adding the following in view did load in .m fie:

[self.WebView setDelegate:self];

添加 DBD 提供的代码:

Add the code as provided by DBD:

(void)webViewDidFinishLoad:(UIWebView *)webView {
   NSCachedURLResponse *resp = [[NSURLCache sharedURLCache] cachedResponseForRequest:webView.request];
   NSLog(@"%@",[(NSHTTPURLResponse*)resp.response allHeaderFields]);
}
