I can convert from rtf string to attributed string using following:

 NSAttributedString *attributedStr = [[NSAttributedString alloc] initWithData:data options:@{NSDocumentTypeDocumentAttribute:NSRTFTextDocumentType} documentAttributes:nil error:nil];

Now how can i convert back from attributedString to rtf string?

You want to use -dataFromRange:documentAttributes:error:

NSAttributedString *str = [[NSAttributedString alloc] initWithString:@"YOLO" attributes:nil];
NSData *data = [str dataFromRange:(NSRange){0, [str length]} documentAttributes:@{NSDocumentTypeDocumentAttribute: NSRTFTextDocumentType} error:NULL];
[data writeToFile:@"/me.rtf" atomically:YES];

Of course you'd want to have some attributes instead of "YOLO", but you get the idea.

Also, if you're looking to simply write this to disk, then fileWrapperFromRange:documentAttributes:error: might even be a better option. You can find more about reading and writing from the Attributed String Programming Guide

  • I Used NSDictionary *documentAttributes = [NSDictionary dictionaryWithObjectsAndKeys:NSRTFTextDocumentType ,NSDocumentTypeDocumentAttribute, nil]; NSData *rtfData = [txtView.attributedText dataFromRange:NSMakeRange(0, txtView.attributedText.length) documentAttributes:documentAttributes error:NULL]; NSString *rtfString = [[NSString alloc] initWithData:rtfData encoding:NSUTF8StringEncoding]; – Hassy Jun 10 '14 at 06:43
