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.

Server side:

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.

Remove All -viewDidUnload Snippets From Your Project's VCs

As Apple's Official Doc said:

-viewDidUnload is deprecated in iOS 6.0. Views are no longer purged under low-memory conditions and so this method is never called.

Meanwhile, it's better to remove all -viewDidUnload implements from projects that the deployment target is iOS 6.0 or later. But removing it one by one is boring, especially you've hundreds of controllers & several projects.

So, is there any script or command can do this batch job?

/*
  Disable deprecated-declarations warning.
  See http://clang.llvm.org/docs/UsersManual.html#diagnostics_pragmas
  
  Basic workflow:
  
    1. push current warnings onto stack
    2. ignore warning we know will get thrown
    3. do dodgy thing that causes warning
    4. pop warnings - go back to what we had before we started fiddling with them
