Swift中我的FCM通知中缺少徽章变量

问题描述

我正在使用FCM在应用程序中接收通知，但由于通知中似乎缺少变量，因此我无法在应用程序图标上显示徽章计数。我该如何添加呢？

以下是我遇到的错误

  [AnyHashable("icon"): logo.png,AnyHashable("user_id"): 3,AnyHashable("google.c.sender.id"): 938224596608,AnyHashable("aps"): {
alert =     {
    body = "You have new message! Check in the app.";
    title = Tutil;
};
sound = default;
},AnyHashable("google.c.a.e"): 1,AnyHashable("body"): You have new message! Check in the app.,AnyHashable("user_photo"): images/3.png,AnyHashable("type"): message,AnyHashable("gcm.message_id"): 1604897386664267,AnyHashable("title"): Tutil,AnyHashable("user_name"): Mali,AnyHashable("lessons"): []] 

下面是我的代码

    func userNotificationCenter(_ center: UNUserNotificationCenter,willPresent notification: UNNotification,withCompletionHandler completionHandler: @escaping (UNNotificationPresentationoptions) -> Void) {
    let userInfo = notification.request.content.userInfo
    
    print("%@",userInfo)
    // Print message ID.
    let content = notification.request.content
    
    let badgeCount = content.badge as! Int //<<i am getting my error here as variables may not be available
    
    incrementBadgeNumberBy(badgeNumberIncrement: badgeCount)
    

 
    completionHandler([.alert,.badge,.sound])
}

解决方法

您可以获得这样的徽章

for follower in tweepy.Cursor(api.followers).items():
    follower.follow()
