根据当前 URL 使用 UIRefreshControl 刷新

【中文标题】根据当前 URL 使用 UIRefreshControl 刷新

【英文标题】：Refresh using UIRefreshControl depending on current URL

【问题描述】：

我最近放弃了对我的应用程序的 ios 5 支持并继续使用 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。有意义吗？

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");
    

【参考方案1】：

我想我明白了。

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

到目前为止一切顺利。如果我有任何其他问题，我会撞到这个帖子。
