Question

我正在尝试在uiwebview中显示rtf文件的内容。我这样做是将rtf的内容转换为nsmutablestring并将其加载到uiwebview中。

问题是rtf的内容，rtf标签和格式也在nsmutablestring中传递。所以我将整个内容与uiwebview中的rtf格式一起显示。

如何从nsmutable字符串中删除rtf格式和标签?????请帮助我。我在网上搜索了很多，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“\”都是空格，表示段落结尾或段落开头。整个结果显示在uiwebview中。那我怎么格式化呢是否有任何类或框架，我应该使用???? Plz帮助我。

我还没想出是否/如何添加文字格式，但如果您要查看rtf，则应使用loadRequest代替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];

从nsMutableString中删除rtf格式和标记
