在iOS中未收到FCM通知

Question

我一直试图在我的ios应用程序中获取firebase推送通知很长一段时间.我已经尝试了我能找到的互联网上的一切.但遗憾的是没有运气.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];

    return YES;
}

- (void)tokenRefreshNotification:(NSNotification *)notification {
    // Note that this callback will be fired everytime a new token is generated, including the first

    // 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]

在日志中,我能够看到为我的设备生成令牌,当我向令牌应用程序发送通知时,它在后台时没有收到通知.

但是,当我启动我的应用程序时,它会调用applicationReceivedRemoteMessage:,我可以看到已发出警报.

可能有什么问题请提前帮助和感谢!

Answer 1

我的项目发生这种情况的原因是因为我使用了与我的开发数据库生成的相同设备令牌 ...结果我需要删除并重新安装我的手机上的应用程序并注册通知以获取新的设备令牌并生成新的FCM注册ID ..有效,我成功收到了我的通知.

希望这可以帮助.
