Pass from UIUserNotificationTypeNone to UIUserNotificationTypeAlert | UIUserNotificationTypeBadge | UIUserNotificationTypeSound

问题:

Do you know a way to pass from UIUserNotificationTypeNone to UIUserNotificationTypeAlert | UIUserNotificationTypeBadge | UIUserNotificationTypeSound (iOS8)?

To pass to UIUserNotificationTypeNone works well but not when the user try to switch again to enable ...

This is my code:

 // Register for Push Notifications, if running iOS 8                     if ([application respondsToSelector:@selector(registerUserNotificationSettings:)])                     {                         UIUserNotificationType userNotificationTypes = (UIUserNotificationTypeAlert | UIUserNotificationTypeBadge | UIUserNotificationTypeSound);                         UIUserNotificationSettings * settingsAvailable = [UIUserNotificationSettings settingsForTypes:userNotificationTypes categories:nil];                         [application registerUserNotificationSettings:settingsAvailable];                         [application registerForRemoteNotifications];                     }                      else                     {                         // Register for Push Notifications before iOS 8                         [application registerForRemoteNotificationTypes:(UIRemoteNotificationTypeBadge | UIRemoteNotificationTypeAlert | UIRemoteNotificationTypeSound)];                     } 

After switch to enable the method of delegate "didRegisterUserNotificationSettings"

// Register to receive notifications [application registerForRemoteNotifications];  NSLog(@"The app is registered for the types: %@", notificationSettings); 

returns:

The app is registered for the types: <UIUserNotificationSettings: 0x15e9e790; types: (none);> 

Thanks in advance

That's because the notification setting has been turned off in the system setting.
