从nsMutableString中删除rtf格式和标记

Question

我试图在uiwebview中显示rtf文件的内容。我通过将rtf的内容放入nsmutablestring并将其加载到uiwebview中来实现此目的。

问题是伴随着rtf的内容，rtf标签和格式也在nsmutablestring中传递。所以我在uiwebview中将整个内容与rtf格式一起显示。

我如何去除nsmutable字符串的rtf格式和标签？ PLZ帮助我。我在网上搜索了很多，但没有取得令人满意的结果。

的代码如下：

UIWebView *webView = [[UIWebView alloc]init]; 
NSString *path = [[NSBundle mainBundle] pathForResource:@"Home" ofType:@"rtf"]; 
NSMutableString *rtfString = [[NSMutableString alloc] initWithContentsOfFile:path encoding:NSUTF8StringEncoding error:NULL]; 
NSMutableString *htmlString = [NSMutableString stringWithFormat:@"<font face=\"verdana\" size=\"2\" color=\"green\">%@</font>",rtfString]; 
[webView loadHTMLString:htmlString baseURL:nil];  

这是RTF文件的输出，这是在各段之间显示的UIWebView

{\rtf1\ansi\ansicpg1252\cocoartf1038\cocoasubrtf290 
{\fonttbl\f0\fnil\fcharset0 LucidaGrande;} 
{\colortbl;\red255\green255\blue255;}

所有“\”是空格这表示段落结束或段落开始。这整个结果将显示在uiwebview中。所以我如何格式化这个。有什么课程或框架，我应该使用???? Plz帮助我。

我还没有想出如果/如何添加文本格式，但如果您尝试查看rtf，则应该使用loadRequest而不是loadHTMLString。

UIWebView *webView = [[UIWebView alloc]init]; 
NSString *path = [[NSBundle mainBundle] pathForResource:@"Home" ofType:@"rtf"]; 
NSURL *url = [NSURL fileURLWithPath:path]; 
NSURLRequest *request = [NSURLRequest requestWithURL:url]; 
[webview loadRequest:request];
