typedef NS_OPTIONS(NSUInteger, UIRemoteNotificationType) {
    UIRemoteNotificationTypeNone    = 0,
    UIRemoteNotificationTypeBadge   = 1 << 0,
    UIRemoteNotificationTypeSound   = 1 << 1,
    UIRemoteNotificationTypeAlert   = 1 << 2,
    UIRemoteNotificationTypeNewsstandContentAvailability = 1 << 3,
} NS_ENUM_AVAILABLE_IOS(3_0);
 

UIRemoteNotificationTypeNone ＝ 0，

UIRemoteNotificationTypeBadge ＝ 1，

UIRemoteNotificationTypeSound ＝ 2，

UIRemoteNotificationTypeAlert ＝ 4，

UIRemoteNotificationTypeNewsstandContentAvailability ＝ 8

通過 UIRemoteNotificationType type = [[UIApplicationsharedApplication] enabledRemoteNotificationTypes];可以得知type的值，根據type的值可以判斷出使用者在通知設定中是如何設定的。

比如：type ＝ 3，那麼使用者開啟的是UIRemoteNotificationTypeBadge和UIRemoteNotificationTypeSound；

    type ＝ 6，那麼使用者開啟的是UIRemoteNotificationTypeSound和UIRemoteNotificationTypeAlert，

以此類推即可~
