why wechat(微信) can do this? APNS push can Wake up parent App in background?

Hi, everyone!

I have a question.

Why WeChat can use PUSH Notification to activate the application in background ?Even activate active the application which closed by user?

I know WeChat use Notification Service,but it can not active parent App in background!

So,WeChat can unlimited use Silent Push?


大家好。

我有一个疑问。

为什么微信的通话推送,可以激活应用?甚至是启动被用户主动关闭的应用?

我知道他起码是用了Notification Service,但是Notification Service也不能启动Parent App(主应用)啊。

难道微信可以无限量使用Silent Push?
