我正在我的app.i中集成FCM通知和云消息，其遵循与firebase doc中提到的完全相同的步骤。即使我尝试过FCM提供的示例代码。它只是抛出一些警告<FIRInstanceID/WARNING> Failed to fetch APNS token Error Domain=com.firebase.iid Code=1001 "The operation couldn’t be completed. and <FIRMessaging/WARNING> FIRMessaging registration is not ready with auth credentials.
任何人都可以帮我解决它。我正在谷歌搜索一周，但没有任何帮助我得到。我用Appdelegate.m编写的代码是
- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {
// Register for remote notifications
if (floor(NSFoundationVersionNumber) <= NSFoundationVersionNumber_iOS_7_1) {
// iOS 7.1 or earlier
UIRemoteNotificationType allNotificationTypes =
(UIRemoteNotificationTypeSound | UIRemoteNotificationTypeAlert | UIRemoteNotificationTypeBadge);
[application registerForRemoteNotificationTypes:allNotificationTypes];
} else {
// iOS 8 or later
// [END_EXCLUDE]
UIUserNotificationType allNotificationTypes =
(UIUserNotificationTypeSound | UIUserNotificationTypeAlert | UIUserNotificationTypeBadge);
UIUserNotificationSettings *settings =
[UIUserNotificationSettings settingsForTypes:allNotificationTypes categories:nil];
[[UIApplication sharedApplication] registerUserNotificationSettings:settings];
[[UIApplication sharedApplication] registerForRemoteNotifications];
}
// [START configure_firebase]
[FIRApp configure];
// [END configure_firebase]
// Add observer for InstanceID token refresh callback.
[[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(tokenRefreshNotification:)
name:kFIRInstanceIDTokenRefreshNotification object:nil];
return YES;
}
// [START receive_message]
- (void)application:(UIApplication *)application didReceiveRemoteNotification:(NSDictionary *)userInfo
fetchCompletionHandler:(void (^)(UIBackgroundFetchResult))completionHandler {
// 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
// Print message ID.
NSLog(@"Message ID: %@", userInfo[@"gcm.message_id"]);
// Pring full message.
NSLog(@"%@", userInfo);
}
// [END receive_message]
// [START refresh_token]
- (void)tokenRefreshNotification:(NSNotification *)notification {
// Note that this callback will be fired everytime a new token is generated, including the first
// time. So if you need to retrieve the token as soon as it is available this is where that
// should be done.
NSString *refreshedToken = [[FIRInstanceID instanceID] token];
NSLog(@"InstanceID token: %@", refreshedToken);
// Connect to FCM since connection may have failed when attempted before having a token.
[self connectToFcm];
// TODO: If necessary send token to appliation server.
}
// [END refresh_token]
// [START connect_to_fcm]
- (void)connectToFcm {
[[FIRMessaging messaging] connectWithCompletion:^(NSError * _Nullable error) {
if (error != nil) {
NSLog(@"Unable to connect to FCM. %@", error);
} else {
NSLog(@"Connected to FCM.");
}
}];
}
// [END connect_to_fcm]
- (void)applicationDidBecomeActive:(UIApplication *)application {
[self connectToFcm];
}
// [START disconnect_from_fcm]
- (void)applicationDidEnterBackground:(UIApplication *)application {
[[FIRMessaging messaging] disconnect];
NSLog(@"Disconnected from FCM");
}
// [END disconnect_from_fcm]
希望尽快得到答复。 提前谢谢！

您似乎需要拥有＆＃34;优先级＆＃34;设置为＆＃34;高＆＃34;如果您希望在应用程序处于后台时显示通知：
Firebase IOS push notification doesn't work when app is closed

我在iOS应用程序中做了同样的事情。 FCM和GCM不适用于iOS。不管别人怎么说，它都没有机会发挥作用。我花了两个星期的时间在网上到处寻找和寻找帖子。 iOS只接受APNS推送通知。让自己远离头痛并从应用程序开始。
编辑： 这是FCM的最新存储库。给它一个镜头，看看它是什么来的。 https://github.com/firebase/quickstart-ios 它似乎与我在iOS版本上工作时尝试的有点不同。 @Chris，这是你用来实现你的版本的代码分支吗？

我也有同样的问题。我得到“连接到FCM”消息和令牌，似乎所有内容都完美集成，但无法接收任何通知。
但是，我立即收到通知，但在没有任何代码更改和证书更改或删除后，我无法再收到任何通知。
在这里查看我的代码，它是一个cocos2d应用程序。
func didLoadFromCCB()
{
...
setupPushNotification()
}
func setupPushNotification () {
let application = UIApplication.sharedApplication()
// Register for remote notifications
if #available(iOS 8.0, *) {
let settings: UIUserNotificationSettings =
UIUserNotificationSettings(forTypes: [.Alert, .Badge, .Sound], categories: nil)
application.registerUserNotificationSettings(settings)
application.registerForRemoteNotifications()
} else {
// Fallback
let types: UIRemoteNotificationType = [.Alert, .Badge, .Sound]
application.registerForRemoteNotificationTypes(types)
}
FIRApp.configure()
// Add observer for InstanceID token refresh callback.
NSNotificationCenter.defaultCenter().addObserver(self, selector: "tokenRefreshNotification:",
name: kFIRInstanceIDTokenRefreshNotification, object: nil)
NSNotificationCenter.defaultCenter().addObserver(self, selector: "didBecomeActive:", name: UIApplicationDidBecomeActiveNotification, object: nil)
NSNotificationCenter.defaultCenter().addObserver(self, selector: "didEnterBackground:", name: UIApplicationDidEnterBackgroundNotification, object: nil)
}
// [START refresh_token]
func tokenRefreshNotification(notification: NSNotification) {
let refreshedToken = FIRInstanceID.instanceID().token()!
print("InstanceID token: \(refreshedToken)")
// Connect to FCM since connection may have failed when attempted before having a token.
connectToFcm()
}
// [END refresh_token]
// [START connect_to_fcm]
func connectToFcm() {
FIRMessaging.messaging().connectWithCompletion { (error) in
if (error != nil) {
print("Unable to connect with FCM. \(error)")
} else {
print("Connected to FCM.")
}
}
}
// [END connect_to_fcm]
func didBecomeActive(application:UIApplication) {
NSLog("Did Become Active")
connectToFcm()
}
func didEnterBackground(application: UIApplication) {
NSLog("Did enter background")
FIRMessaging.messaging().disconnect()
NSLog("Disconnected from FCM.")
}
}
我不知道如何只有一个正确的通知，然后它变成了表格。 ：（
让我知道如何解决这个问题。

尝试发送此
curl --header "Authorization: key={YOUR_API_KEY}" --header Content-Type:"application/json" https://fcm.googleapis.com/fcm/send -d "{\"to\":\"{YOUR_DEVICE_TOKEN}\",\"content_available\":true,\"priority\":\"high\",\"notification\":{\"title\":\"TEST\",\"sound\":\"default\",\"body\":\"IT WORKS!\",\"badge\":1}}"
它对我有用。 （显然，首先注册推送通知然后打印出设备令牌）
