James P有正确的答案(编辑),但此处是显示和隐藏指标的代码。
http://developer.apple.com/library/ios/#documentation/uikit/ reference/UIWebViewDelegate_ protocol/Reference/Reference.html UIViewDelegate
- (void)webViewDidStartLoad:(UIWebView *)webView {
[UIApplication sharedApplication].networkActivityIndicatorVisible = YES;
// Other stuff...
}
之后
- (void)webViewDidFinishLoad:(UIWebView *)webView {
[UIApplication sharedApplication].networkActivityIndicatorVisible = NO;
// Other stuff...
}
另外,你还可能想检查失败,并将活动指标隐藏在那里......
- (void)webView:(UIWebView *)webView didFailLoadWithError:(NSError *)error {
[UIApplication sharedApplication].networkActivityIndicatorVisible = NO;
// Other stuff...
}
第一部分 加上“IDWebViewDelegate”代表,你可以采用以下方法。
– webView:shouldStartLoadWithRequest:navigationType:
– webViewDidStartLoad:
– webViewDidFinishLoad:
– webView:didFailLoadWithError:
