我最近放弃了对我的应用程序的 iOS 5 支持，并开始使用 UIRefreshControl。我的设置和工作并不完美。我从这个线程的目标是让它刷新，如果它是我网站中的当前网址，或者如果它在另一个网站（如 youtube）上，让它重新加载并刷新回我的网站。说得通？

到目前为止，我已经尝试过这样做但没有成功。我去了 YouTube，NSLog 将其显示为我当前的站点。我对此感到困惑，因为它显然不是。

任何帮助，将不胜感激。

-(void)handleRefresh:(UIRefreshControl *)refresh {

    NSString *string = @"MySite.com";
    if ([string rangeOfString:@"MySite"].location == NSNotFound) {

        // Reload my data
        NSString *fullURL = @"http://www.MySite.com/";
        NSURL *url = [NSURL URLWithString:fullURL];
        NSURLRequest *requestObj = [NSURLRequest requestWithURL:url];
        [webView loadRequest:requestObj];

        [(UIWebView *)[self.view viewWithTag:999] reload];
        [overlay postMessage:@"Reloading" duration:1 animated:YES];

        //set the title while refreshing
        refresh.attributedTitle = [[NSAttributedString alloc]initWithString:@"Refreshing the View"];
        //set the date and time of refreshing
        NSDateFormatter *formattedDate = [[NSDateFormatter alloc]init];
        [formattedDate setDateFormat:@"MMM d, h:mm a"];
        NSString *lastupdated = [NSString stringWithFormat:@"Last Updated on %@",[formattedDate stringFromDate:[NSDate date]]];
        refresh.attributedTitle = [[NSAttributedString alloc]initWithString:lastupdated];
        lastupdated:[UIColor colorWithRed:(87.0/255.0) green:(108.0/255.0) blue:(137.0/255.0) alpha:1.0];

        //end the refreshing
        [refresh endRefreshing];
        NSLog(@"String does not contain MySite");

    } else {

        // Reload my data
        NSString *fullURL = webView.request.URL.absoluteString;
        NSURL *url = [NSURL URLWithString:fullURL];
        NSURLRequest *requestObj = [NSURLRequest requestWithURL:url];
        [webView loadRequest:requestObj];

        [(UIWebView *)[self.view viewWithTag:999] reload];
        [overlay postMessage:@"Reloading" duration:1 animated:YES];

        //set the title while refreshing
        refresh.attributedTitle = [[NSAttributedString alloc]initWithString:@"Refreshing the View"];
        //set the date and time of refreshing
        NSDateFormatter *formattedDate = [[NSDateFormatter alloc]init];
        [formattedDate setDateFormat:@"MMM d, h:mm a"];
        NSString *lastupdate = [NSString stringWithFormat:@"Last Updated on %@",[formattedDate stringFromDate:[NSDate date]]];
        refresh.attributedTitle = [[NSAttributedString alloc]initWithString:lastupdate];
        lastupdate:[UIColor colorWithRed:(87.0/255.0) green:(108.0/255.0) blue:(137.0/255.0) alpha:1.0];

        //end the refreshing
        [refresh endRefreshing];
        NSLog(@"String contains MySite");
    }

}

想我明白了。

字面上不得不改变顶部： NSString *string = webView.request.URL.absoluteString;

到目前为止，一切都很好。如果我有任何其他问题，我会碰到这个线程。
