Automatic selection of the destination App in UIDocumentINteractionController without presenting the available Apps

Question

I am developing and App for sharing an audio file with Whatsapp. Since, I am only focused on Whatsapp, I am not interested on showing other available apps such as VLC or Telegram.

Can I select Whatsapp App to share the file without presenting the menu for choosing? In other words, can I avoid presentOpenInMenuFromRect:inView:anmiated:?

Answer 1

You need to use UIDocumentInteractionController UTI: net.whatsapp.audio

Custom URL scheme for whatsApp

  _documentController = [UIDocumentInteractionController interactionControllerWithURL:fileURL];
_documentController.delegate = self;
_documentController.UTI = @"net.whatsapp.audio";
[_documentController presentOpenInMenuFromRect:CGRectZero inView:self.view animated:YES]

When triggered, WhatsApp will immediately present the user with the contact/group picker screen. The media will be automatically sent to a selected contact/group.
