我在视图控制器按钮操作中有以下代码:

- (IBAction)requestPermissions:(id)sender
{
  DDLogInfo(@"Start permission requesting.");

  if ([[UIApplication sharedApplication] respondsToSelector:@selector(registerForRemoteNotifications)]){
    [[UIApplication sharedApplication] registerForRemoteNotifications];
  } else {
    [[NSNotificationCenter defaultCenter] addObserver:self
                                             selector:@selector(didBecomeActive:)
                                                 name:UIApplicationDidBecomeActiveNotification
                                               object:nil];
    [[UIApplication sharedApplication]
     registerForRemoteNotificationTypes:UIRemoteNotificationTypeAlert|UIRemoteNotificationTypeBadge|UIRemoteNotificationTypeSound];
  }
}

注册完成后,didBecomeActive会发布通知,我正在检查用户做了什么:

-(void)didBecomeActive:(NSNotification *)notification
{
   if([[UIApplication sharedApplication] enabledRemoteNotificationTypes] == UIRemoteNotificationTypeNone){
// if user decline 
}
} else {
 // if user accept
}

所以我的问题是:如果用户拒绝接收推送通知并稍后决定启用它们(设置 - >通知中心 - >我的应用程序),则会出现一个惊喜:设置中启用了"警报","徽章"和"声音" ,但应用程序返回 UIRemoteNotificationTypeNone.

有什么想法有什么不对？

注:我知道这些方法现在已经过时,所以请不要告诉我用registerForRemoteNotifications:和UIUserNotificationSettings,它已经完成.
