APNS 设备令牌是否会在创建后更改? [英] Does the APNS device token ever change, once created?

问题描述

Once created does the push notification device token ever change?

Example when the app is updated? or in any other case it can change??

解决方案

From [Apple Documentation ApplePushService]2

The form of this phase of token trust ensures that only APNs generates the token which it will later honor, and it can assure itself that a token handed to it by a device is the same token that it previously provisioned for that particular device—and only for that device.

If the user restores backup data to a new device or reinstalls the operating system, the device token changes.
