启动故障排除后推送通知传送失败 [英] Troubleshooting post-boot push notification delivery failures

问题描述

我的应用程序成功接收推送通知，如果这两个在后台启动每个至少运行一次，当强制关闭（感谢PushKit）。

My app receives push notifications successfully if run at least once per boot both in the background and when force closed (thanks to PushKit).

如果我重新启动设备，我不会，直到我启动的应用程序至少一次接受任何推送。

If I reboot the device, I won't receive any pushes until I launch the app at least once.

我怎样才能得到这个场景的工作？我运行最新版的X code和iOS（8.3）

How can I get this scenario working? I'm running latest Xcode and iOS (8.3)

如果我留在后台运行，当我重新启动设备的应用程序，该应用程序仍显示在近期]菜单但不推收到，没有的AppDelegate入口点击（我有反正）。

If I leave the app running in the background when I reboot the device, the app still shows up in the recents menu however no pushes are received and no AppDelegate entry points are hit (that I have anyways).

• 所有推/通知权限启用以及后台应用刷新


• 背景模式功能被启用（VoIP，一键，取）

推荐答案

的问题是，应用程序就要休眠回调之前更新凭据。

The problem was that the app was going dormant before the callback to update credentials.

解决的办法是在 didLaunchWithOptions 来启动一个后台任务，并最终在 didUpdatePushCredentials 功能后台任务。

The solution was to start a background task in didLaunchWithOptions and end the background task in the didUpdatePushCredentials function.
