我已经在我的iOS应用中集成了Firebase云消息传递功能,但没有使用cocoa pods。 Firebase分析工作正常,但在真实设备上收不到FCM令牌,只能在模拟器上接收到。在真实设备上,我一直收到以下错误:
Failed to fetch default token Error Domain=com.firebase.iid Code=501 "(null)"
- 我已在Firebase上上传了用于开发和生产的.p12证书。
- 我已检查了我的应用程序的bundle ID以及Firebase控制台上的bundle ID。
- 我已启用了我的App ID的推送通知功能。
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。
