How to change file extension from .txt to .rtf in ios programatically?
<p>How do I change a file extension from .txt to .rtf in iOS programatically?<br>
In xml parsing I'm getting rtf data with rtf tags.<br>
Is it possible to save data in a rtf file without tags? 
If we load that file, this was loading with rtf tags in webview.<br>
If we open and save that file physically, it opens in the WebView.<br>
Is there any way to do this task (File Open &amp; Save) programatically using iOS.  </p>

<p>If we load the rtf file from FTP server, upto tables it was loading(only plain text before tables)</p>
