一次推送显示两次 iOS 推送通知横幅 [英] iOS Push Notification Banner shown twice for a single Push

问题描述

我注意到发送推送通知会导致以下行为:

I've noticed that sending a Push notification results in the following behavior:

看看横幅是如何在短暂延迟后再次显示的?

See how the banner is shown a second time, after a short delay?

起初我以为我们的后端错误地发送了 2 个推送通知，一个接一个.

At first I thought that our backend was mistakenly sending 2 push notifications, one after the other.

然而，这似乎是单个推送通知的默认 iOS 行为.显示横幅，然后立即再次显示".这导致了 gif 中显示的这个令人不安的 UI.横幅似乎收到了两次.

However, this appears to be default iOS behavior for a single Push notification. The banner is shown, then immediately "shown again". This results in this jittery UI shown in the gif. The banner appears to be received twice.

使用 iOS 9.0.2 测试.

Tested using iOS 9.0.2.

我不记得从其他向我发送推送通知的应用程序中看到过这种行为.我是否做错了什么会导致横幅显示两次?

I do not recall seeing this behavior from other apps that send me Push Notifications. Am I doing something wrong that would cause the banner to show twice?
