Question

我目前正在使用控制台和Firebase功能设置Firebase推送通知。我浏览了github上可用的文档以获得所有设置，但由于某些原因，我的实际手机上没有出现我正在测试它，而不是模拟器。当我从Firebase控制台向手机发送推送通知时，我的控制台中会显示该消息，但是没有声音或横幅出现在我的手机中。这是我在app appate中的代码。

Answer 1

您需要在'willPresent notification'委托方法中将完成处理程序中的'UNNotificationPresentationOptions'传递给

completionHandler（[。alert，.badge，.sound]）

由于

Answer 2

该应用程序可能正在运行，尝试将应用程序置于后台并再试一次。检查iPhone的设置，看看是否为您的应用禁用了横幅广告。或者，如果你发送一个静音推。祝好运。
