根据我们的经验，通知的交付率远非100％，而整个iOS的安装次数仅为50到100.从理论上讲，没有上限.

In our experience notifications have far from a 100% delivery rate, and that's with only between 50 and a 100 installs across iOS. In theory there is no cap set in place.

我知道的唯一限制是在短时间内将相同的通知多次发送到同一设备.

The only limits I'm aware of is sending an identical notification to the same device multiple times within a short window of time.
