從nsMutableString中刪除rtf格式和標記

Question

我試圖在uiwebview中顯示rtf文件的內容。我通過將rtf的內容放入nsmutablestring並將其加載到uiwebview中來實現此目的。

問題是伴隨着rtf的內容，rtf標籤和格式也在nsmutablestring中傳遞。所以我在uiwebview中將整個內容與rtf格式一起顯示。

我如何去除nsmutable字符串的rtf格式和標籤？ PLZ幫助我。我在網上搜索了很多，但沒有取得令人滿意的結果。

的代碼如下：

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];  

這是RTF文件的輸出，這是在各段之間顯示的UIWebView

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

所有「\」是空格這表示段落結束或段落開始。這整個結果將顯示在uiwebview中。所以我如何格式化這個。有什麼課程或框架，我應該使用???? Plz幫助我。

我還沒有想出如果/如何添加文本格式，但如果您嘗試查看rtf，則應該使用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];
