Variable Qualifiers

You use the following lifetime qualifiers for variables just like you would, say, const.

__strong
__weak
__unsafe_unretained
__autoreleasing

• __strong is the default. An object remains “alive” as long as there is a strong pointer to it.

Client side:

An app must register with Apple Push Notification service (APNs) to receive remote notifications sent by the app’s push provider. In iOS 8 and later, registration has four stages:

1. Register the notification types your app supports using registerUserNotificationSettings:.
2. Register to receive push notifications via APNs by calling your app’s registerForRemoteNotifications method.
3. Store the device token returned to the app delegate by the server for a successful registration, or handle registration failure gracefully.
4. Forward the device token to the app’s push provider.
