判斷iOS裝置的PUSH通知設定狀態(開啟。。。／關閉)

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 = [[UIApplication
sharedApplication] 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~
