ios - 在 XCode 9 中的 IOS 上使用 Firebase 消息传递

Question

每次我尝试运行时，我的应用程序都会使模拟器崩溃，并显示以下消息。

Function boringssl_context_get_peer_sct_list: line 1757 received sct extension length is less than sct data length

我不确定原因，但我希望获得有关以下 3 行正确顺序的反馈:

FirebaseApp.configure()
Messaging.messaging().delegate = self  
// IOS 9 
application.registerForRemoteNotifications() 

或

// IOS10
UNUserNotificationCenter.current().requestAuthorization(options: [.alert, .sound, .badge])
UIApplication.shared.registerForRemoteNotifications()

Answer 1

这是最好的方法。

先请求许可，获得批准后，再注册推送通知

UNUserNotificationCenter.current().requestAuthorization(options: [.alert, .sound, .badge]) { (granted, error) in

        print("permision granted \(granted)")

        guard granted else { return }

        UNUserNotificationCenter.current().getNotificationSettings { (settings) in
            print("Notification Settings \(settings)")
            guard settings.authorizationStatus == .authorized else { return }

            DispatchQueue.main.async {
                // register
                UIApplication.shared.registerForRemoteNotifications()
            }

        }
    }
