将推送通知发送到多个iOS设备时有限制吗? [英] is there a limit when sending push notifications to multiple iOS devices?

问题描述

因此，我大约有1000个iOS用户安装了我的应用程序.我试图通过应用程序的后端面板向这些用户发送推送通知，但是，我的设备未收到推送通知.我还问了一些用户，其中一些用户说他们确实收到了推送通知，而有些则没有.

So, I have about 1000 iOS users installed my app. I tried to send push notification to these users thru my app's backend panel, however, my devices did not receive the push notification. I also asked some users, and some of them said they did receive the push notification and some did not.

我想知道为什么不是所有的1000个iOS用户都能成功收到推送通知.起初，我认为这与我的应用程序有关，因为我的设备具有尚未发布给公众的最新更新.因此，我继续删除获得的所有设备令牌，然后再次注册我的设备以测试推送通知.

I was wondering why not all of the 1000 iOS users receive the push notification successfully. At first, I thought it has to do with my applications, because my device has the latest update that is yet to release to public. So I went on and delete all the device tokens I got, and register my device again to test the push notification.

这一次，我的设备成功收到了来自后端面板的推送通知.因此，我确定接收推送通知时编码部分没有问题.(我对此进行了多次测试，并确保成功发送和接收推送)

This time, my device received the push notification from backend panel successfully. So, I am sure there is nothing wrong with the coding part on receiving push notifications. (I ran multiple test on this and sure that push are send and receive successfully)

只有当我尝试向iOS用户发送批量推送通知时，这种情况才会发生.

It only happens when I tried to send bulk push notifications to iOS users.

那么，发送推送通知是否有限制?像它只允许发送可能是100个用户?还是可能存在无效的设备令牌，以便在完成发送给所有用户之前停止推送?但是在什么情况下设备令牌无效?卸载用户的设备令牌可能是原因吗?

so, is sending push notification has a limit? like it only allows to send may be to 100 users? or may be there are invalid device token so that pushes are stopped before finish sending to all users? but in what situation device token become invalid? will uninstalled user's device token may be a cause?

推荐答案

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.
