以下是苹果对此的评价,

If APNs attempts to deliver a notification but the device is offline,
the notification is stored for a limited period of time,and delivered
to the device when it becomes available.

Only one recent notification for a particular application is stored.
If multiple notifications are sent while the device is offline,each
new notification causes the prior notification to be discarded. This
behavior of keePing only the newest notification is referred to as
coalescing notifications.

If the device remains offline for a long time,any notifications that were being stored for it are discarded.
