推荐答案

James P的答案正确(^'ed)，但这是显示和隐藏指标的代码.

James P has the right answer (^'ed), but here is the code to show and hide the indicator.

在 UIWebViewDelegate ...

- (void)webViewDidStartLoad:(UIWebView *)webView { [UIApplication sharedApplication]workActivityIndicatorVisible = YES; // Other stuff... }

然后

- (void)webViewDidFinishLoad:(UIWebView *)webView { [UIApplication sharedApplication]workActivityIndicatorVisible = NO; // Other stuff... }

您可能还想检查故障并在那里隐藏活动指示器...

Also you probably want to check for failures and hide the activity indicator there as well...

- (void)webView:(UIWebView *)webView didFailLoadWithError:(NSError *)error { [UIApplication sharedApplication]workActivityIndicatorVisible = NO; // Other stuff... }
