我无法在后台收到推送通知。 iOS 10 - 对象 - Firebase

Question

我正在尝试在后台收到通知，我按照文档Firebase和Apple进行了操作，但我无法解决问题。

问题：当我从控制台Firebase发送通知时，我收到完全通知的通知，但是从Firebase发送相同的通知，我的应用程序在后台我没有收到任何数据，但是如果我打开应用程序，应用程序会显示我通知，但从不在后台。有趣的是，第二天我通过封闭的应用程序在后台收到所有通知。

设备：iPhone 6 - v10.0.1

编辑：我的有效载荷：

当我在Firebase中发送通知时，我收到此有效负载，我在Firebase中选择了高优先级，但我没有在有效负载中获得任何优先级。

我的代码：

#define SYSTEM_VERSION_GRATERTHAN_OR_EQUALTO(v)  ([[[UIDevice currentDevice] systemVersion] compare:v options:NSNumericSearch] != NSOrderedAscending)

@interface AppDelegate ()

@end

@implementation AppDelegate
