我正在通过firebase云消息传递实现推送通知，当我在设备上获取警报时，它实际上是两次广告，但是在通知列表列表面板上，它看起来像预期。我正在尝试解决这个问题，但我是新手推动通知，但我找不到在哪里设置了重复的位置。我正在测试iPad 3 Sunning IOS 9.3.5。您能否查看我是否在didFinishLaunchingWithOptions中将其设置两次，或者我可以在哪里设置两次？一如既往的感谢。
didFinishLaunchingWithOptions：
func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplicationLaunchOptionsKey: Any]?) -> Bool {
// Override point for customization after application launch.
// UI Theme selection
if UserDefaults.standard.object(forKey: "Theme") != nil {
Theme.selectedTheme = UserDefaults.standard.bool(forKey: "Theme") ? 1 : 2
}
// setting up Firebase
FirebaseApp.configure()
Messaging.messaging().delegate = self
// setting up notification delegate
if #available(iOS 10.0, *) {
//iOS 10.0 and greater
UNUserNotificationCenter.current().delegate = self
let authOptions: UNAuthorizationOptions = [.alert, .badge, .sound]
//Solicit permission from the user to receive notifications
UNUserNotificationCenter.current().requestAuthorization(options: authOptions, completionHandler: { granted, error in
DispatchQueue.main.async {
if granted {
print("didFinishLaunchingWithOptions iOS 10: Successfully registered for APNs")
} else {
//Do stuff if unsuccessful...
print("didFinishLaunchingWithOptions iOO 10: Error in registering for APNs: (String(describing: error))")
}
}
})
} else {
//iOS 9
let type: UIUserNotificationType = [UIUserNotificationType.badge, UIUserNotificationType.alert, UIUserNotificationType.sound]
let setting = UIUserNotificationSettings(types: type, categories: nil)
UIApplication.shared.registerUserNotificationSettings(setting)
print("didFinishLaunchingWithOptions iOS 9: Successfully registered for APNs")
}
UIApplication.shared.registerForRemoteNotifications()
//get application instance ID
InstanceID.instanceID().instanceID { (result, error) in
if let error = error {
print("didFinishLaunchingWithOptions: Error fetching remote instance ID: (error)")
} else if let result = result {
print("didFinishLaunchingWithOptions: Remote instance ID token: (result.token)")
}
}
// setting up remote control values
let _ = RCValues.sharedInstance
GIDSignIn.sharedInstance().clientID = FirebaseApp.app()?.options.clientID
Crashlytics().debugMode = true
Fabric.with([Crashlytics.self])
// // TODO: Move this to where you establish a user session
// self.logUser()
return true
}
didRegisterForRemoteNotificationsWithDeviceToken：
func application(_ application: UIApplication, didRegisterForRemoteNotificationsWithDeviceToken deviceToken: Data) {
let tokenParts = deviceToken.map { data -> String in
return String(format: "%02.2hhx", data)
}
let token = tokenParts.joined()
print(" didRegisterForRemoteNotificationsWithDeviceToken : devcice token is: (token)")
if #available(iOS 10.0, *) {
// For iOS 10 display notification (sent via APNS)
UNUserNotificationCenter.current().delegate = self
Messaging.messaging().apnsToken = deviceToken // mandatory!!
let authOptions: UNAuthorizationOptions = [.alert, .badge, .sound]
UNUserNotificationCenter.current().requestAuthorization(
options: authOptions,
completionHandler: {_, _ in })
} else {
Messaging.messaging().apnsToken = deviceToken // mandatory!!
let settings: UIUserNotificationSettings =
UIUserNotificationSettings(types: [.alert, .badge, .sound], categories: nil)
application.registerUserNotificationSettings(settings)
}
}
didReceiveRemoteNotification：
func application(_ application: UIApplication, didReceiveRemoteNotification userInfo: [AnyHashable: Any],
fetchCompletionHandler completionHandler: @escaping (UIBackgroundFetchResult) -> Void) {
print("didReceiveRemoteNotification with handler : Received new push Notification")
// If you are receiving a notification message while your app is in the background,
// this callback will not be fired till the user taps on the notification launching the application.
// TODO: Handle data of notification
// With swizzling disabled you must let Messaging know about the message, for Analytics
Messaging.messaging().appDidReceiveMessage(userInfo)
// Print message ID.
if let messageID = userInfo[ fcmMessageIDKey] {
print("didReceiveRemoteNotification: Message ID: (messageID)")
}
// Print full message.
print("didReceiveRemoteNotification: Push notificationMessage is: (userInfo)")
completionHandler(UIBackgroundFetchResult.newData)
}
打开通知时的控制台打印：
didReceiveRemoteNotification with handler : Received new push Notification
didReceiveRemoteNotification: Push notificationMessage is: [AnyHashable("google.c.a.c_id"): 1354763473839437035, AnyHashable("google.c.a.udt"): 0, AnyHashable("gcm.notification.sound2"): enabled, AnyHashable("gcm.n.e"): 1, AnyHashable("gcm.message_id"): 0:1558780267039787%6f9b8aab6f9b8aab, AnyHashable("google.c.a.ts"): 1558780266, AnyHashable("google.c.a.tc"): 1, AnyHashable("google.c.a.e"): 1, AnyHashable("google.c.a.c_l"): Test push , AnyHashable("aps"): {

我发现了错误。在didFinishLaunchingWithOptions中执行didRegisterForRemoteNotificationsWithDeviceToken的通知，我再次设置了通知。因此，在该方法中，我只处理收到的令牌。
func application(_ application: UIApplication, didRegisterForRemoteNotificationsWithDeviceToken deviceToken: Data) {
let tokenParts = deviceToken.map { data -> String in
return String(format: "%02.2hhx", data)
}
let token = tokenParts.joined()
print(" didRegisterForRemoteNotificationsWithDeviceToken : devcice token is: (token)")
Messaging.messaging().apnsToken = deviceToken // mandatory!!
}
希望这对他人有帮助。
