对于一个项目，我需要在 iPad 上显示 RTF 文件的内容。经过一番搜索，我发现您可以在 UIWebView 中加载 RTF 文件。但是，当我这样做时，会显示文件的内容，但缺少表格边框和图像。粗体/斜体/下划线文本工作正常。
我用来显示文件的代码：
NSURL *url = [[NSBundle mainBundle] URLForResource:@"A" withExtension:@".rtf"];
NSLog(@"URL: %@", url);
NSURLRequest *req = [NSURLRequest requestWithURL:url];
[_webView loadRequest:req];
RTF 文件：
https://dl.dropbox.com/u/4966217/A.rtf
如何在我的应用程序中显示图像和表格边框？
If you want only to show rtf file then you can also use QLPreviewController.
It supports many file formats for preview.
Here is the documentation link for QLPreviewController:
http://developer.apple.com/library/ios/#documentation/NetworkingInternet/Reference/QLPreviewController_Class/Reference/Reference.html
And here is sample code : http://developer.apple.com/library/ios/#samplecode/DocInteraction/Introduction/Intro.html#//apple_ref/doc/uid/DTS40010052
试试这个代码
NSString *filePath = [[NSBundle mainBundle] pathForAuxiliaryExecutable:@"A.rtf"];
NSURL *fileURL = [[NSURL alloc] initFileURLWithPath:filePath];
NSURLRequest *requestObj = [NSURLRequest requestWithURL:fileURL];
[_webView loadRequest:requestObj];
将其转换为 html
