Swift：从Parse.com注册通知不会保持启用状态

Question

我已将程序配置为接收来自Parse的通知，并且我已使用以下行启用它：

var pushSettings : UIUserNotificationSettings = UIUserNotificationSettings(forTypes: .Alert, categories: nil)

application.registerUserNotificationSettings(pushSettings)

application.registerForRemoteNotifications()

let userNotificationTypes = (UIUserNotificationType.Alert | UIUserNotificationType.Badge | UIUserNotificationType.Sound);

let settings = UIUserNotificationSettings(forTypes: userNotificationTypes, categories: nil)

application.registerUserNotificationSettings(settings)

application.registerForRemoteNotifications()

声明在

中

func application(application: UIApplication, didFinishLaunchingWithOptions launchOptions: [NSObject: AnyObject]?) -> Bool

来自我的appDelegate，但是当我关闭我的程序并重新启动它时，所有参数都被重置，我将它们“关闭”

有没有人有想法？
