iphone - Sending a contact from an iOS app via bluetooth

Question

I am trying to allow a user, who is running my app, to send a contacts vcard (vcf) via bluetooth to another iOS device. The problem is, that the receiving device should not be required to run the same app.

Is there a possibiliy to accomplish this?

If there is not - is it at least possible to have Gamekit to establish a session, when the receiving device is running the same app, but without requiring the (receiving) user to start the peerPicker-dialog?

Any help and hints are appreciated!

Answer 1

First option: seems to be impossible.

Second option: Works. I implemented a GKSessionDelegate for receiving incoming connections. This session is startet together with the app. For establishing the connection with a receiver, I used the well known GKPeerPickerControllerDelegate.

残っている問題の1つは、送信者が利用可能なピアのリストに自分自身を表示することです（受信者もバックグラウンドで実行されているため）。これに対する私の解決策は、送信者がGKPeerPickerControllerを開始するとすぐに、GKSession.available=NOを設定することです。
