如何注册Win8定期图块通知? [英] How to register for Win8 periodic tile notifications?

问题描述

我正在开发Win8-UI-App(以前称为Metro ...)，并尝试实现Periodic(

I am working on a Win8-UI-App (previously called Metro...) and trying to implement Periodic (Documentation for different methods) Tile Updates (Live Tiles) for the first time.

我在互联网上找到了一些非常好的资源，并且能够做到这一点.不幸的是，我应该在哪里注册通知的问题仍未解决:

I found a couple of very good resources on the internet and was able to do it. Unfortunately the question of where I should register for the notifications remained unsolved:

我是否必须每次 注册通知(例如，在App.xaml.cs OnLaunched()方法中)? -或者还有其他更专业的方法吗? (我可以想象是否要保存已注册的服务，或者是否可以访问变量以查看通知是否已注册?)

Do I have to register for Notifications every time the app starts (e.g. in the App.xaml.cs OnLaunched() Method)? - Or is there an other, more professional way to do so? (I could imagine to save if I already registered for the service or is there a variable I can access to see whether notifications are registered?)

谢谢！

Call the StartPeriodicUpdate or StartPeriodicUpdateBatch method each time your app is launched or brought into focus. This ensures that the tile content will be updated each time the user launches or switches to the app.

因此，应用启动和应用恢复是呼叫 StartPeriodicUpdate .
