【中文标题】iOS swift中没有收到推送通知？【英文标题】：Push notification is not receiving in iOS swift? 【发布时间】：2018-05-05 11:31:51 【问题描述】：我正在使用FCM 进行推送通知。 FCM 已连接，设备注册成功，我可以打印设备令牌，但设备没有收到通知。
一般 -> 功能选项卡 -> 在后台模式下启用推送通知和远程通知。
在这里注册设备以进行远程通知。
func application(
_ application: UIApplication,
didRegisterForRemoteNotificationsWithDeviceToken deviceToken: Data
)
let trimEnds:String! =
deviceToken.description.trimmingCharacters(
in: CharacterSet(charactersIn: "<>"))
()
let cleanToken:String! =
trimEnds.replacingOccurrences(of: " ", with: "")
()
let token = deviceToken.map String(format: "%02.2hhx", $0) .joined()
print(token)
UserDefaults.standard.set(token, forKey: "deviceToken")
UserDefaults.standard.synchronize()
#if DEBUG
//For Firebase
FIRInstanceID.instanceID().setAPNSToken(deviceToken, type: FIRInstanceIDAPNSTokenType.sandbox)
#else
FIRInstanceID.instanceID().setAPNSToken(deviceToken, type: FIRInstanceIDAPNSTokenType.prod)
#endif
print("Device Token:", token)
这里我调用didReceiveRemoteNotification方法在注册设备上接收通知：
func application(_ application: UIApplication, didReceiveRemoteNotification userInfo: [AnyHashable: Any])
print("-=-=-=-=-\nDid receive notification\n-=-=-=-",userInfo)
print("-=-=-=-=-\n")
NotificationCenter.default.post(name: Notification.Name(rawValue: "notification_recieved"), object: nil)
if userInfo.index(forKey: "chat_id") != nil
print("messag push")
if (AppUtility?.hasValidText(User.userID))!
//let friendImage = userInfo["path"] as! String
let chatID = userInfo["chat_id"] as! String
let friendId = userInfo["to"] as! String
let unRead = userInfo["unread"] as! String
print(unRead)
UnReadMsgs = unRead
let dictAPS = userInfo["aps"] as! NSDictionary
let dict = dictAPS["alert"] as! NSDictionary
let friendName = dict["title"] as! String
let friendMsg = dict["body"] as! String
if(UIApplication.shared.applicationState == UIApplicationState.active)
print("app is Active")
if let wd = self.window
var VC = wd.rootViewController
if(VC is UINavigationController)
VC = (VC as! UINavigationController).visibleViewController
if(VC is ChatViewController!)
print("Chat Screen")
let chatVC : ChatViewController = VC as! ChatViewController
if chatVC.chatId == chatID
print("Same Chat")
self.clearChatWithChatID(chatID)
else
CustomNotificationView.showNotificationPopUp(self.window!, name: friendName, msg: friendMsg, image: "", chat: chatID, friendID: friendId)
playSound()
print("Other Chat")
else
let nc = NotificationCenter.default
nc.post(name: Notification.Name(rawValue: "MessageGet"),
object: nil,
userInfo: ["unRead":unRead,
"date":Date()])
CustomNotificationView.showNotificationPopUp(self.window!, name: friendName, msg: friendMsg, image: "", chat: chatID, friendID: friendId)
playSound()
print("Other Screen")
else
print("app is in BG")
var vc:ChatViewController!
vc = ChatViewController(nibName: "ChatViewController", bundle: nil)
vc.chatId = chatID
vc.otherUserId = friendId
vc.otherUserName = friendName
vc.channelRef = self.channelRef.child("\(chatID)")
vc.friendImageLink = "\(resourceUrl)\("")"
let nav = UINavigationController(rootViewController: vc)
nav.isNavigationBarHidden = false
if let wd = self.window
var VC = wd.rootViewController
if(VC is UINavigationController)
VC = (VC as! UINavigationController).visibleViewController
VC!.present(nav, animated: false, completion:
)
else
let val = userInfo["aps"] as! [String:AnyObject];
let alert = NSString(string: val["alert"] as! String)
if(UIApplication.shared.applicationState == UIApplicationState.inactive || UIApplication.shared.applicationState == UIApplicationState.background)
showUserInfo(application, didReceiveRemoteNotification: userInfo)
else
print("top most vc \(String(describing: UIApplication.shared.keyWindow!.rootViewController!.topMostViewController().presentingViewController)) and presentedvc \(String(describing: UIApplication.shared.keyWindow!.rootViewController!.topMostViewController().presentedViewController))")
if UIApplication.shared.keyWindow!.rootViewController!.topMostViewController() is NYAlertViewController
let newAlert = AppUtility?.getDisplayAlertController(title: "FitFlow", messageText: alert as String)
let nvVc = UIApplication.shared.keyWindow!.rootViewController!.topMostViewController().presentedViewController
nvVc?.present(newAlert!, animated: true, completion: nil)
return
AppUtility?.displayAlert(title:"FitFlow", messageText: alert as String,UIApplication.shared.keyWindow!.rootViewController!.topMostViewController())
我已经通过保留断点进行了测试，它根本不调用didReceiveRemoteNotification 方法。如何使用上述方法接收推送通知？
【问题讨论】：
你的有效载荷是什么样的？您是否在设备上启用了通知？您是在设备还是模拟器上进行测试？ 如果你的didReceiveRemoteNotification 根本没有被调用，那么请删除它的所有代码块，直到你找出它没有被击中的原因。我的意思是其余的代码没有必要查看帮助。
@Honey Hey 仍然无法找到解决方案？？？任何想法
- 生成 APNs 密钥。 firebase.google.com/docs/cloud-messaging/ios/certs - 上传 APNs 到 Firebase 项目的密钥。在 firebase 项目 => 设置 => 云消息 => iOS 应用程序配置 => APNs 身份验证密钥 - 还要确保您的应用程序在首次启动时请求通知权限。 // 向用户请求权限 FCM.requestPermissions(); FCM.getToken()
你不觉得吗，在尚未尝试/回复 cmets 时添加赏金是没用的。
【参考方案1】：
我之前也遇到过这个问题。
这需要 FCM 令牌，而不是 APNS 令牌。
为此， 您的 AppDelegate 类需要这些 -
import Firebase
import UserNotifications
import FirebaseMessaging
class AppDelegate: UIResponder,
UIApplicationDelegate,
UNUserNotificationCenterDelegate,
FIRMessagingDelegate
然后订阅didFinishLaunchingWithOptions中的消息传递委托
func application(_ application: UIApplication,
didFinishLaunchingWithOptions launchOptions: [UIApplicationLaunchOptionsKey: Any]?) -> Bool
GIDSignIn.sharedInstance().clientID =
"Your client id"
DispatchQueue.main.async
FIRApp.configure()
FIRMessaging.messaging().remoteMessageDelegate = self
if #available(iOS 10, *)
UNUserNotificationCenter.current().requestAuthorization(options:[.badge, .alert, .sound]) (granted, error) in
application.registerForRemoteNotifications()
// iOS 9 support
else if #available(iOS 9, *)
UIApplication.shared.registerUserNotificationSettings(UIUserNotificationSettings(types: [.badge, .sound, .alert], categories: nil))
UIApplication.shared.registerForRemoteNotifications()
// iOS 8 support
else if #available(iOS 8, *)
UIApplication.shared.registerUserNotificationSettings(UIUserNotificationSettings(types: [.badge, .sound, .alert], categories: nil))
UIApplication.shared.registerForRemoteNotifications()
// iOS 7 support
else
application.registerForRemoteNotifications(matching: [.badge, .sound, .alert])
return true
// 你不再需要 didRegisterForRemoteNotificationsWithDeviceToken 方法了
func application(_ application: UIApplication, didRegisterForRemoteNotificationsWithDeviceToken deviceToken: Data)
你从代表
didRegisterForRemoteNotificationsWithDeviceToken收到的令牌没有用，您需要使用 FIRInstanceID.instanceID().token()
在您的 applicationDidBecomeActive 中添加以下代码，这将检查 FCM 令牌刷新，并优雅地处理。
func applicationDidBecomeActive(_ application: UIApplication)
NotificationCenter.default.addObserver(self, selector:
#selector(tokenRefreshNotification), name:
NSNotification.Name.firInstanceIDTokenRefresh, object: nil)
@objc func tokenRefreshNotification(notification: NSNotification)
if let refreshedToken = FIRInstanceID.instanceID().token()
print("InstanceID token: \(refreshedToken)")
UserDefaults.standard.set(refreshedToken, forKey: "deviceToken")
self.sendFCMTokenToServer(token: refreshedToken)
/*
Connect to FCM since connection may
have failed when attempted before having a token.
*/
else
connectToFcm()
func updatePushNotificationWebservice()
/*
if you want to save that token on your server
Do that here.
else use the token any other way you want.
*/
func connectToFcm()
FIRMessaging.messaging().connect (error) in
if (error != nil)
print("Unable to connect with FCM. \(String(describing: error))")
else
print("Connected to FCM.")
/*
**this is the token that you have to use**
print(FIRInstanceID.instanceID().token()!)
if there was no connection established earlier,
you can try sending the token again to server.
*/
let token = FIRInstanceID.instanceID().token()!
self.sendFCMTokenToServer(token: token)
使用从FIRInstanceID.instanceID().token()! 获得的令牌进行调试，并在 >project>Cloud 消息选项卡中使用具有相同令牌的推送通知 Firebase 控制台。

【参考方案2】：从后端将优先级设置为高可以解决我的问题。
请从 Firebase 控制台检查->云消息（左下项）发送推送通知。
