objective c - Passing value from CloudKit app to another user -

I am new to CloudKit and am currently analyzing CloudKitAtlas from the developer library. I create an app where I want to "share" another user of the same app.

I have CK Container in my personal database, where the user has created all his created dictionaries, now I want to give him the possibility of sharing some part of my data with other user (make public container with identifier ). I know that it is possible to check each email address from the address book and the person receiving the result has app installed. Then the user can choose who will be able to see his data.

The question is how will any other user show the app "Look at CkTechner on my shared data" :

Anyone else has already done something like this Can do?

You can list all users from your address book The app is installed using the container search All Resource User EfosSppliment Handler Method. This will return an array so that you can get a record id. If you want to share something with one of those users, then create a record where you had placed that ID in the field at the beginning of your app, you will create a specially purchased subscription for that field Looks and compares his own user's record id. So if a record is created with your ID in the TO field, you will receive a notification. Anyone you want to send to another user should be in the public database. I am doing some work on this.
