在iOS中未收到FCM通知

Question

我一直试图在ios应用中获得长时间的Firebase推送通知。我已经尝试了互联网上找到的所有东西。但可悲的是没有运气。 任何帮助，将不胜感激。

我通过Firebase控制台发送通知。

这里是我的代码：

#import "AppDelegate.h" 

#if defined(__IPHONE_10_0) && __IPHONE_OS_VERSION_MAX_ALLOWED >= __IPHONE_10_0 
@import UserNotifications; 
#endif 

@import Firebase; 
@import FirebaseInstanceID; 
@import FirebaseMessaging; 

#if defined(__IPHONE_10_0) && __IPHONE_OS_VERSION_MAX_ALLOWED >= __IPHONE_10_0 
@interface AppDelegate() <UNUserNotificationCenterDelegate, FIRMessagingDelegate> 
@end 
#endif 

@implementation AppDelegate 


- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions { 
    // Override point for customization after application launch. 

    // [START configure_firebase] 
    [FIRApp configure]; 
    // [END configure_firebase] 

    if (floor(NSFoundationVersionNumber) <= NSFoundationVersionNumber_iOS_9_x_Max) { 
     UIUserNotificationType allNotificationTypes = 
     (UIUserNotificationTypeSound | UIUserNotificationTypeAlert | UIUserNotificationTypeBadge); 
     UIUserNotificationSettings *settings = 
     [UIUserNotificationSettings settingsForTypes:allNotificationTypes categories:nil]; 
     [[UIApplication sharedApplication] registerUserNotificationSettings:settings]; 
    } else { 
     // iOS 10 or later 
#if defined(__IPHONE_10_0) && __IPHONE_OS_VERSION_MAX_ALLOWED >= __IPHONE_10_0 
     UNAuthorizationOptions authOptions = 
     UNAuthorizationOptionAlert 
     | UNAuthorizationOptionSound 
     | UNAuthorizationOptionBadge; 
     [[UNUserNotificationCenter currentNotificationCenter] 
     requestAuthorizationWithOptions:authOptions 
     completionHandler:^(BOOL granted, NSError * _Nullable error) { 
     } 
     ]; 

     // For iOS 10 display notification (sent via APNS) 
     [[UNUserNotificationCenter currentNotificationCenter] setDelegate:self]; 
     // For iOS 10 data message (sent via FCM) 
     [[FIRMessaging messaging] setRemoteMessageDelegate:self]; 
#endif 
    } 

    [[UIApplication sharedApplication] registerForRemoteNotifications]; 

    // Add observer for InstanceID token refresh callback. 
    [[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(tokenRefreshNotification:) 
               name:kFIRInstanceIDTokenRefreshNotification object:nil]; 

    return YES; 
} 

// [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); 

    NSLog(@"id = ---------- %@",[[[UIDevice currentDevice] identifierForVendor] UUIDString]); 


    [[NSNotificationCenter defaultCenter] postNotificationName:@"fcmtoken" object: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. 
} 
// [END refresh_token] 

- (void)application:(UIApplication *)application didReceiveRemoteNotification:(NSDictionary *)userInfo { 
    // 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"]);

    // Print full message. 
    NSLog(@"willPresentNotification: %@", userInfo); 
} 

// Receive data message on iOS 10 devices. 
- (void)applicationReceivedRemoteMessage:(FIRMessagingRemoteMessage *)remoteMessage {

    NSLog(@"message Recived = %@", [remoteMessage appData]); 

    UIAlertView *alert = [[UIAlertView alloc] initWithTitle:@"ROFL" 
                message:@"Dee dee doo doo." 
                delegate:self

    //  [[FIRInstanceID instanceID] setAPNSToken:deviceToken type:FIRInstanceIDAPNSTokenTypeProd]; 


} 

- (void)applicationWillResignActive:(UIApplication *)application { 
    // Sent when the application is about to move from active to inactive state. This can occur for certain types of temporary interruptions (such as an incoming phone call or SMS message) or when the user quits the application and it begins the transition to the background state. 
    // Use this method to pause ongoing tasks, disable timers, and invalidate graphics rendering callbacks. Games should use this method to pause the game. 
} 

- (void)applicationDidEnterBackground:(UIApplication *)application { 
    // Use this method to release shared resources, save user data, invalidate timers, and store enough application state information to restore your application to its current state in case it is terminated later. 
    // If your application supports background execution, this method is called instead of applicationWillTerminate: when the user quits. 

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

- (void)applicationWillEnterForeground:(UIApplication *)application { 
    // Called as part of the transition from the background to the active state; here you can undo many of the changes made on entering the background. 
} 

- (void)applicationDidBecomeActive:(UIApplication *)application { 
    // Restart any tasks that were paused (or not yet started) while the application was inactive. If the application was previously in the background, optionally refresh the user interface.

在日志中我能够看到令牌为我的设备产生的，还当我通知发送到令牌应用程序没有收到通知，当它在后台。

但是，当我启动我的应用程序时，它调用applicationReceivedRemoteMessage:，我可以看到令人不快的警报。

有什么问题请提前帮助，谢谢！

Answer 1

当您的APP进入后台时，通知消息会通过Apple APNS服务发送，所以我认为您的.cer是错误的;苹果有两个.cer在编码/ AppStore中推送通知，如果你的APP没有进入AppStore，请尝试使用developerment .cer来做。

我的英语不好，但可能对你有帮助！

====编辑==== 试试这个吗？ >性能 - -

NSString *pushToken = [[[[deviceToken description]

      stringByReplacingOccurrencesOfString:@"<" withString:@""] 
         stringByReplacingOccurrencesOfString:@">" withString:@""] 
         stringByReplacingOccurrencesOfString:@" " withString:@""];

对不起possting的问题，但它可能会帮助别人......我通过启用推送通知的能力在Xcode上.xcodeproj 8.1

点击解决这个问题>启用推送通知

我重新创建了provisiong配置文件。

Answer 3

这发生在我的项目的原因是因为我使用的是相同的设备令牌与我的发展产生分贝......原来我需要删除并重新安装应用程序我的手机上，并注册通知获取新的设备令牌并生成新的FCM注册ID ..工作，我成功地收到我的通知。

希望这会有所帮助。
