//遵循代理
<UIWebViewDelegate>
//設(shè)置代理
_webView.delegate = self;
#pragma mark 開始加載數(shù)據(jù)
- (void)startLoad
{
    NSURL* url = [NSURL URLWithString:urlStr];
    NSURLRequest* request = [NSURLRequest requestWithURL:url];
    [self.webView loadRequest:request];
}
#pragma mark webViewDelegate
// 開始加載
- (void)webViewDidStartLoad:(UIWebView *)webView
{
    [MBProgressHUD showHUDAddedTo:self.view animated:YES];
}

// 結(jié)束加載
- (void)webViewDidFinishLoad:(UIWebView *)webView
{
    [MBProgressHUD hideHUDForView:self.view animated:YES];
}

// 開始加載失敗
- (void)webView:(UIWebView *)webView didFailLoadWithError:(NSError *)error
{
    [MBProgressHUD hideHUDForView:self.view animated:YES];
}
