by offline do you mean device without internet?? or the app is not running? – Ebert

@Ebert app is not running – Herakleion

You may try GCM for Android, and APNS for iOS – Isaak

@Isaak tnx for your reply but we know how to send push notification throught apns and gcm but we dint know how to integrated it with xmpp and send it to offline users – Herakleion

Answer 1

It would be easier to use Parse or something similar for push notifications, you can use it for both android and ios.

another option is to expand your systems functionality a little bit, and add a web service that correlates to the application and sends the pushes, that can give you some more control over syncing.

You can check receiver is offline or not using below method.

- (void)xmppRoom:(XMPPRoom *)sender didFetchModeratorsList:(NSArray *)items

If your friend is offline than you have to upload message/image to particular server using web service. when your friend will become online than after success connect to xmpp stream he has to call web services for get offline messages. Using this you can easily manage offline messages. I had done this and works fine for me. Let me know if any help.
