Xcode控制台中显示Firebase/InAppMessaging错误

为什么会出现这种错误？ 我也正确地阅读了文档、设置代码和项目，但是当我从firebase deshboard发送InAppMessaging并打开应用程序时，我收到了这个错误

 pod 'Firebase/Database'
 pod 'Firebase/InAppMessagingDisplay'
 pod 'Firebase/Messaging'

---

这背后有2-3个原因

• Firebase未在didFinishLaunchingWithOptions配置/初始化
• FCM令牌已过期或无效，并且未添加刷新令牌
• 使用无效/不同的GoogleService-Info.plist i、 e如果您在同一项目中使用2 GoogleService-Info.plist进行开发和生产。因此，请确保在安装应用程序时，正确的GoogleService-Info.plist正在启动

吊舱“火力基地/信息” 如果您也在使用InAppMessagingDisplay，请同时安装此pod

pod“Firebase/InAppMessagingDisplay” 在didFinishLaunchingWithOptions启动Firebase

我也有同样的问题。你解决了吗？是的，我的问题通过添加pod步骤1-#pod“Firebase/InAppMessagingDisplay”步骤2-pod安装步骤3-通过代码消息配置Firebase解决了。消息（）.shouldEstablishDirectChannel=true步骤3-从iPhone中删除应用程序并重新安装-向firebase发送APNS令牌，但添加

shouldEstablishDirectChannel

更改应用程序接收firebase消息的行为

func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplicationLaunchOptionsKey: Any]?) -> Bool {

    window = UIWindow(frame: CGRect(x: 0, y: 0, width: kDeviceWidth, height: kDeviceHeight))
    
    FirebaseApp.configure()
    NotificationCenter.default.addObserver(self, selector: #selector(tokenRefreshNotification), name: NSNotification.Name.InstanceIDTokenRefresh, object: nil)
    Messaging.messaging().delegate = self
    Messaging.messaging().shouldEstablishDirectChannel = true

    UNUserNotificationCenter.current().delegate = self
    
    if #available(iOS 10.0, *) {
                   
        let authOptions: UNAuthorizationOptions = [.alert, .badge, .sound]
        UNUserNotificationCenter.current().requestAuthorization(
            options: authOptions,
            completionHandler: {_, _ in })
    } else {
        let settings: UIUserNotificationSettings =
            UIUserNotificationSettings(types: [.alert, .badge, .sound], categories: nil)
        application.registerUserNotificationSettings(settings)
    }
    
    application.registerForRemoteNotifications()
}
// [START refresh_token]
func messaging(_ messaging: Messaging, didReceiveRegistrationToken fcmToken: String) {
    
 //You save or send fcm token to your sever
}


//+++++++++++++++++++++++
// FCM Token Get Refreshed
@objc func tokenRefreshNotification(_ notification: Notification) {
    getFCMToken()
}
private func getFCMToken() {
    
    InstanceID.instanceID().instanceID { (result, error) in
        
        if error == nil {
            
            if let result = result {
                let fcmToken = result.token
                //Save or send to your server
            }
        }
    }
