我如何HTML在我们的 iPhone 中显示此内容UI，因为这将包含文本、超链接和图像。

您可以执行以下操作。

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;

 }

让我知道它是否有效..

编码快乐！！！！

如果您打算按HTML原样显示实体，我建议您使用UIWebView. HTML您可以在方法中将其作为字符串传递loadHTMLString:

如果您希望用户以网页形式查看内容，那么加载 urlUIWebView是最好和最简单的方法。像这样：

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