How do I copy audio file to clipboard and send via iMessage ios 8

I have successfully copy image to clipboard and then send it in SMS by using below code

 UIPasteboard *pasteboard = [UIPasteboard generalPasteboard];
 NSData *data= UIImagePNGRepresentation([UIImage imageNamed:@"so_close_disappointed_meme.png"]);
[pasteboard setData:data forPasteboardType:@"public.png"];

Now i am trying to send audio file in iMessage using same Scheme but it did not show any paste option in Message Window

 UIPasteboard *pasteboard = [UIPasteboard generalPasteboard];
 NSString *path = [[NSBundle mainBundle] pathForResource:@"03 - Aye Khuda"ofType:@"mp3"];
 NSURL *url = [[NSURL alloc] initWithString:path];
 NSData *data = [NSData dataWithContentsOfURL:url];
 [pasteboard setData:data forPasteboardType:@"public.mp3"];

Any Suggestion will be appreciated.Thanks
