从nsMutableString中删除rtf格式和标签

Question

我正在尝试在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。

问题与rtf的内容一起出现，rtf标记和格式也在nsmutablestring中传递。因此，整个内容与rtf格式一起显示在uiwebview中。

如何从nsmutable字符串中剥离rtf格式和标签？我在网上搜索了很多内容，但没有令人满意的结果。

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，显示在uiwebview中

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

段落之间的所有“ \”都是空白，表示段落末尾或段落开始。整个结果按原样显示在uiwebview中。那我该如何格式化呢？我应该使用任何类或框架吗？

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];
