Question

我有RSS个Feed列表，我需要在iPhone中显示每个Feed的详细信息。我从服务器上获得了所有RSS个Feed，我正在tableview中显示。现在，在选择一行时，我需要在RSS内容中显示来自服务器的HTML Feed的说明，如： -

<a href=\"http://timesofindia.indiatimes.com/articleshow/4881843.cms\"><img border=\"0\" hspace=\"10\" align=\"left\" style=\"margin-top:3px;margin-right:5px;\" src=\"http://timesofindia.indiatimes.com/photo/4881843.cms\" /></a>Cadila Pharmaceutical will seek the govt's nod in two days for initiating clinical trials for a vaccine against swine flu.<img width='1' height='1' src='http://timesofindia.feedsportal.com/c/33039/f/533968/s/1f181b11/mf.gif' border='0'/><div class='mf-viral'><table border='0'><tr><td valign='middle'><a href=\"http://share.feedsportal.com/viral/sendEmail.cfm?lang=en&title=Cadila+to+apply+for+clinical+trials+for+swine+flu+vaccine&link=http%3A%2F%2Ftimesofindia.indiatimes.com%2Farticleshow%2F4881843.cms\" target=\"_blank\"><img src=\"http://res3.feedsportal.com/images/emailthis2.gif\" border=\"0\" /></a></td><td valign='middle'><a href=\"http://res.feedsportal.com/viral/bookmark.cfm?title=Cadila+to+apply+for+clinical+trials+for+swine+flu+vaccine&link=http%3A%2F%2Ftimesofindia.indiatimes.com%2Farticleshow%2F4881843.cms\" target=\"_blank\"><img src=\"http://res3.feedsportal.com/images/bookmark.gif\" border=\"0\" /></a></td></tr></table></div><br/><br/><a href=\"http://da.feedsportal.com/r/133515347892/u/0/f/533968/c/33039/s/1f181b11/a2.htm\"><img src=\"http://da.feedsportal.com/r/133515347892/u/0/f/533968/c/33039/s/1f181b11/a2.img\" border=\"0\"/></a><img width=\"1\" height=\"1\" src=\"http://pi.feedsportal.com/r/133515347892/u/0/f/533968/c/33039/s/1f181b11/a2t.img\" border=\"0\"/>

如何在我们的iPhone HTML中显示此UI内容，因为这将包含文字，超链接和图片。

在这种情况下使用UIWebview是否正确，因为UIWebView是重量级的。

Answer 1

请阅读此博客： http://www.raywenderlich.com/2636/how-to-make-a-simple-rss-reader-iphone-app-tutorial ，它对你有用。

Answer 2

你可以做类似下面的事情。

首先

 descLbl.text=[self flattenHTML:descLbl.text];//descLbl.text is a text in which you are getting that HTML description...

现在在flattenHTML方法中编写如下...

   - (NSString *)flattenHTML:(NSString *)html {

NSScanner *thescanner;
NSString *text = nil;

thescanner = [NSScanner scannerWithString:html];

while ([thescanner isAtEnd] == NO) {

    [thescanner scanUpToString:@"<" intoString:NULL];

    // find end of tag
    [thescanner scanUpToString:@">" intoString:&text];

     html = [html stringByReplacingOccurrencesOfString:[NSString stringWithFormat:@"\n"] withString:@" "];
    // replace the found tag with a space
    //(you can filter multi-spaces out later if you wish)
    html = [html stringByReplacingOccurrencesOfString:[NSString stringWithFormat:@"%@>", text] withString:@" "];

} // while //

return html;

 }

让我知道它是否正常工作..

快乐编码!!!!

如果您打算按原样显示HTML个实体，我建议您使用UIWebView。您可以在方法HTML

中将此loadHTMLString:作为字符串传递

Answer 4

如果您希望用户将内容视为网页，则在UIWebView中加载网址是最简单最方便的方式。像这样：

UIWebView *webView = [[UIWebView alloc] init];
NSURL *pageurl = [NSURL URLWithString:http://www.google.com];
NSURLRequest *request = [NSURLRequest requestWithURL:pageurl];
[webView loadRequest:request];
