How can I show rtf file with wmf images in ios

Question

I have a .rtf file. It contains images with Windows Metafile Format(wmf). I want to show this file in iOS app. I tried showing it using NSAttributedString and in UIWebView but images are not shown. How can I show it on iOS device ?

EDIT

For NSAttributedString:

var urlpath = NSBundle.mainBundle().pathForResource("txtFile", ofType: "rtf")
var url:NSURL = NSURL.fileURLWithPath(urlpath!)!
if let attributedText = NSAttributedString(fileURL: url, options: [NSDocumentTypeDocumentAttribute:NSRTFTextDocumentType], documentAttributes: nil, error: nil) {
    textView.attributedText = attributedText
}

For UIWebView:

NSString *path = [[NSBundle mainBundle] pathForResource:@"txtFile" ofType:@"rtf"];
NSURL *url = [NSURL URLWithString:path];
[self.webView loadRequest:[NSURLRequest requestWithURL:url]];

EDIT2

I tried converting .rtf file into .rtfd file format.

RTFD file creates a bundle with TXT.rtf and images in files. In TXT.rtf file, images are given as references which are stored separately in RTFD. Like following :

{{\NeXTGraphic img1.png \width40 \height20}¬}

I converted the file into RTFD but issue comes when file contains .wmf images. Images with .wmf file format are not getting converted.

Try converting to rtfd insead of rtf

Rich Text Format Directory, also known as RTFD (due to its extension .rtfd), or Rich Text Format with Attachments

var urlpath = NSBundle.mainBundle().pathForResource("txtFile", ofType: "rtfd")
var url:NSURL = NSURL.fileURLWithPath(urlpath!)!
if let attributedText = NSAttributedString(fileURL: url, options: [NSDocumentTypeDocumentAttribute:NSRTFDTextDocumentType], documentAttributes: nil, error: nil) {
     textView.attributedText = attributedText
}
