我正在使用firebase在iOS中实现推送通知。不幸的是，我遇到firebase没有收到通知的问题。
这是我输出的错误：
****[Firebase/Messaging][I-FCM002019] FIRMessaging received data message, but FIRMessagingDelegate's-messaging:didReceiveMessage: not implemented****
如何解决此问题？我已经在iOS 9.3上测试了它，它运行正常。我使用以下代码：
func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplicationLaunchOptionsKey: Any]?) -> Bool
{
FirebaseApp.configure()
if #available(iOS 10.0, *) {
// For iOS 10 display notification (sent via APNS)
UNUserNotificationCenter.current().delegate = self
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()
// Add observer for InstanceID token refresh callback.
NotificationCenter.default
.addObserver(self, selector: #selector(AppDelegate.tokenRefreshNotification),
name: NSNotification.Name.InstanceIDTokenRefresh, object: nil)
return true
}
func application(_ application: UIApplication, didReceiveRemoteNotification userInfo: [AnyHashable: Any])
{
print(userInfo)
}
func tokenRefreshNotification(_ notification: UIViewController)
{
if let refreshedToken = InstanceID.instanceID().token()
{
print("InstanceID token: \(refreshedToken)")
UserDefaults.standard.set(refreshedToken, forKey: "Device_token")
UserDefaults.standard.synchronize()
}
// Connect to FCM since connection may have failed when attempted before having a token.
connectToFcm()
}
// [START connect_to_fcm]
func connectToFcm()
{
Messaging.messaging().shouldEstablishDirectChannel = true
}
func application(_ application: UIApplication, didRegisterForRemoteNotificationsWithDeviceToken deviceToken: Data)
{
//Tricky line
Messaging.messaging().apnsToken = deviceToken
//InstanceID.instanceID().setAPNSToken(deviceToken, type: InstanceIDAPNSTokenType.unknown)
print("Device Token:", tokenString)
}
func applicationDidBecomeActive(_ application: UIApplication) {
print("applicationDidBecomeActive ")
connectToFcm()
}

您尚未为 IOS 10添加委托方法，还检查您的有效负载是否为mutable-content = true：
