推荐答案

除了DBD提供的答案外，您还需要确保

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。这可以直接在界面建设中完成，或者通过链接网页视图并在视图中添加以下内容。在fm中加载：

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]);
}
