更改传入的推送通知的内容

Question

有没有办法在推送通知出现在手机上之前或之后立即用代码更改（替换）推送通知的传入文本消息？

No. If you're app isn't running then your app doesn't get to even see the push notification before it is displayed to the user or even know its arrived.

If it was running when the push arrived then you can display a location notification (which to the user looks like the same thing).

However that's the situation for standard push notifications, with iOS7 your app could receive background silent push notifications* and then post a location notification to the user which would achieve the same thing you want.

(*provided the user hasn't explicitly terminated the app or it hasn't crashed)
