iOS的应用程序从通知中心失踪

问题：
该应用程序不会出现在通知中心，并通过 registerForRemoteNotificationTypes无法安装完成并推送通知的应用注册后立即收到推送通知：

详细内容：

• 重启设备后，一切都工作得很好后，应用程序通常出现在通知中心。


• 有时在应用程序通知中心显示了安装纸和登记的APN之后（我还无法证实这一点，但我觉得我在这样的情况下跌跌撞撞）。


• 应用程序调用该方法每次 registerForRemoteNotificationTypes 用户登录，每次分别在用户注销与位掩码（ UIRemoteNotificationTypeAlert | UIRemoteNotificationTypeBadge | UIRemoteNotificationTypeSound ）和 UIRemoteNotificationTypeNone 。


• enabledRemoteNotificationTypes 返回正确的值。


• 最初我用注销方法 unregisterForRemoteNotifications ，但我把它改为 registerForRemoteNotificationTypes：UIRemoteNotificationTypeNone 由于suspicians这可能是造成问题的原因。


• 在这两种发展出现此问题，并即席构建和无关的应用程序是否利用x code或iTunes安装。

• The app usually appears in notification center after the device is restarted and after that everything works just fine.
• Sometimes the app shows up in notification center right after intallation and registration for APNs(I still can't confirm this but I think I stumbled upon such situations).
• The app calls the method registerForRemoteNotificationTypes each time a user logins and each time a user logouts respectively with bit masks (UIRemoteNotificationTypeAlert | UIRemoteNotificationTypeBadge | UIRemoteNotificationTypeSound) and UIRemoteNotificationTypeNone.
• enabledRemoteNotificationTypes returns correct values.
• Initially I used the method unregisterForRemoteNotifications on logout but I changed it to registerForRemoteNotificationTypes:UIRemoteNotificationTypeNone due to suspicians that this could be causing the problem .
• This problem occurs in both development and adhoc builds and irrespectively of whether the app is installed via xcode or itunes.
