在IOS设备上使用Firebase推送通知时遇到问题。我从firebase控制台发送消息,然后在日志中显示它,但它没有在我尝试的设备上显示任何通知。
我一直在寻找有类似问题的帖子,我已经尝试了我找到的所有内容,但它仍然无效。
我在firebase上创建了项目,下载了google服务信息文件并将其放在项目的根目录上,在xcode上打开通知,将消息的优先级设置为高,并进行了一些更改。
我还添加了' Firebase / Core'和' Firebase / Messaging'到podfile。
现在我正在使用Firebase为您提供的示例。这是我的代码。

该应用必须在背景中才能显示。

我有同样的问题。选中此question,以确保所有设置均正确。
我遵循了这个answer,这个answer和这个answer,这就是让它为我工作的原因。
但是,有一个简单的解决方法-看起来您必须 设置消息传递委托(Messaging.messaging()。delegate = ...) 在FirebaseApp.configure()之前
含义:
// add this first
Messaging.messaging().delegate = self
// add this second
FirebaseApp.configure()
和:
func application(_ application: UIApplication, didRegisterForRemoteNotificationsWithDeviceToken deviceToken: Data) {
Messaging.messaging().apnsToken = deviceToken
}
还有这个
extension AppDelegate : MessagingDelegate {
func messaging(_ messaging: Messaging, didReceiveRegistrationToken fcmToken: String) {
print("Your Firebase FCM Registration Token: \(fcmToken)")
}
}
