Question

我在没有可可豆荚的iOS应用程序中集成了Firebase云消息。 Firebase分析工作正常。但FCM令牌是在模拟器上接收但不是真实设备。在真实设备上我不断收到错误

无法获取默认令牌Error Domain = com.firebase.iid Code = 501 “（空）”

我上传了用于开发的.p12证书，并在Firebase上发布了
我已检查过我的应用的捆绑包ID以及Firebase控制台上的捆绑包
我的应用ID已启用推送通知。

这是我的代码

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {
    [FIRApp configure];
    [[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(tokenRefreshNotification:)  name:kFIRInstanceIDTokenRefreshNotification object:nil];
}


- (void)application:(UIApplication *)application didRegisterUserNotificationSettings:(UIUserNotificationSettings *)notificationSettings {

    // For iOS 10 display notification (sent via APNS)
    [UNUserNotificationCenter currentNotificationCenter].delegate = self;
    // For iOS 10 data message (sent via FCM)
    [FIRMessaging messaging].remoteMessageDelegate = self;

    [application registerForRemoteNotifications];

}

- (void)application:(UIApplication *)app didRegisterForRemoteNotificationsWithDeviceToken:(NSData *)deviceToken {

    [[FIRInstanceID instanceID] setAPNSToken:deviceToken type:FIRInstanceIDAPNSTokenTypeSandbox];

}

- (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 application server.
}

- (void)connectToFcm {
    // Won't connect since there is no token
    if (![[FIRInstanceID instanceID] token]) {
        return;
    }

    // Disconnect previous FCM connection if it exists.
    [[FIRMessaging messaging] disconnect];

    [[FIRMessaging messaging] connectWithCompletion:^(NSError * _Nullable error) {
        if (error != nil) {
            NSLog(@"Unable to connect to FCM. %@", error);
        } else {
            NSLog(@"Connected to FCM. FCM token - %@", [[FIRInstanceID instanceID] token] );
        }
    }];
}


- (void)applicationDidBecomeActive:(UIApplication *)application {
    [FBSDKAppEvents activateApp];

    [self connectToFcm];

}

- (void)applicationDidEnterBackground:(UIApplication *)application {

    [[FIRMessaging messaging] disconnect];
    NSLog(@"Disconnected from FCM");

}

请帮忙。

Answer 1

我解决了自己的问题。设备的日期和时间不正确。第二个我改为现在的日期＆amp;时间，Firebase开始给我FCM令牌并正确连接。我也从Firebase Notification Console检查了推送通知。它的工作方式比我想象的要好。

问题可能是由于版本问题引起的。实际上我也遇到了同样的问题。我在模拟器上获得了FCM令牌，但在设备上却没有。原因是由于在didFinishLaunchingWithOptions上注册了用户通知设置.... 。我们必须检查设备和模拟器上的版本...如果两者不相同..请检查“ [[UIApplication sharedApplication] registerUserNotificationSettings：settings]” 当前设备版本的条件... Bcz我在didFinishLaunchingWithOptions中限制了> = 10个版本。...

无法在真实设备上获取FCM令牌，但无法进入模拟器
