removing the rtf format and tags from nsMutableString

Question

hello everyone. I am trying to display the contents of a rtf file in uiwebview. I do this by taking the contents of rtf into nsmutablestring and loading it into uiwebview.

The problem is along with the content of rtf, the rtf tags and format is also passed in the nsmutablestring. so i the entire content is displayed along with the rtf format in uiwebview.

How do i strip the rtf format and tags out of nsmutable string????? plz help me. i have searched a lot on web, with no satisfactory result.

The code is as follows :

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];    

This is the output of the rtf file, which is displayed in uiwebview

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

All the "\" in between the paragraphs are white spaces which signifies paragraph end or paragraph start. This entire result is displayed in uiwebview as it is. so how do i format this. is there any class or framework which i should use???? Plz help me.

I havent figured out if/how text formatting can be added but you should use loadRequest instead of loadHTMLString if you are trying to view an rtf.

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];
