我正在使用FCM进行推送通知。 FCM已连接，设备已成功注册，我可以打印设备令牌，但设备未收到通知。
一般而言 - ＆gt;功能选项卡 - ＆gt;在后台模式下启用推送通知和远程通知。
此处注册远程通知设备。
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)
}
我在这里调用了didReceiveRemoteNotification方法来接收已注册设备的通知：
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())
}
}
}
我通过保留断点进行测试，它根本不会调用didReceiveRemoteNotification方法。如何使用上述方法接收推送通知？
答案 0 :(得分：2)
我之前也坚持过这个。
这需要 FCM令牌，而不是 APNS令牌。
要这样做， 您的AppDelegate类需要具有这些 -
import Firebase
import UserNotifications
import FirebaseMessaging
class AppDelegate: UIResponder,
UIApplicationDelegate,
UNUserNotificationCenterDelegate,
FIRMessagingDelegate {
}
- 然后在
中订阅消息传递代理didFinishLaunchingWithOptions
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
func application(_ application: UIApplication, didRegisterForRemoteNotificationsWithDeviceToken deviceToken: Data) { }
您从代理
didRegisterForRemoteNotificationsWithDeviceToken收到的令牌无用，您需要使用 FIRInstanceID.instanceID（）。token（）
在applicationDidBecomeActive中添加以下代码，这将检查FCM令牌刷新，并优雅地处理它。
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)
}
}
}
要进行调试，请使用从FIRInstanceID.instanceID().token()!获取的令牌，并在＆gt;项目＆gt;云消息传递选项卡中使用具有相同令牌的推送通知firebase控制台。
