Question

我最近放弃了iOS 5对我的应用程序的支持，并使用了UIRefreshControl。我并没有完全建立和工作。我在这个帖子中的目标是让它刷新，如果它是我网站上的当前网址，或者它是在像youtube这样的其他网站上，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将它显示为我当前的网站。我很困惑，因为它显然不是。

任何帮助都将不胜感激。

-(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");
    }

}

想想我明白了。

字面上必须改变顶部：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，那么就会遇到这个问题。

根据当前URL使用UIRefreshControl进行刷新
