ios - Check if users are friends before sending push notification in parse.com cloud code -

I'm almost ready to release an iOS app on App Store, but I have trouble switching the cloud from the client Code is push notification.

Each user in the app is in the "user" object pars, and they have the property (array) of each friend.

I want the user to be able to send every other information, but I do not want the client push to be enabled for security purposes.

Basically, when a user sends a message to a friend, I have to figure out what the user is in the friend's friend list, and if he is, send the push notification to that friend with the message .
