Send audio with UIActivityViewController

Question

I'm tring to send an audio file to other apps.

If I only provide the file url, I can send to AirDrop, mail and message app

NSURL *url = [[NSURL alloc]initFileURLWithPath:file];
NSArray *objectsToShare = @[url];

UIActivityViewController *controller = [[UIActivityViewController alloc] initWithActivityItems:objectsToShare applicationActivities:nil];

// Present the controller
[self presentViewController:controller animated:YES completion:nil];

If I add the file name to the object to share I can also send it to clipboard

...
NSArray *objectsToShare = @[@"filename.m4a", url];
...

But how can I send it the other application accepting audio file? For example my application accepts "public.audio" and is listed by other apps that send audio files.

For opening a file in another app you should use the UIDocumentInteractionController ; its guide might be helpful too
