Linkedin-iOS-检测用户取消登录

我在

OAuthStarterKit

中运行并工作了链接（web视图很慢！）基本视图附带了一些基本代码，用于检测弹出web视图何时关闭（请参阅以下函数）

问题是，当用户看到Linkedin登录页面时，它无法检测用户何时单击“取消”按钮。url:

如何过滤“已取消”页面？

过滤/关闭代码 回答！ 这就是我最后在代码中使用的东西！希望它能帮助别人

- (void)webViewDidFinishLoad:(UIWebView *)mwebView
{
    [activityIndicator stopAnimating];
    NSString *html = [mwebView stringByEvaluatingJavaScriptFromString:
                      @"document.body.innerHTML"];

    if ([html rangeOfString:@"Page Not Found"].location != NSNotFound) {
        // This could be any string - I used "Page Not Found" 
        [[NSNotificationCenter defaultCenter]
         postNotificationName:@"loginViewDidFinish"
         object:self
         userInfo:nil];

        [self dismissModalViewControllerAnimated:YES];
    }
}
