再次获取ios push deviceToken

Question

我需要获取deviceToken。 当我向应用程序添加推送通知时，我通过didRegisterForRemoteNotificationsWithDeviceToken收到了didRegisterForRemoteNotificationsWithDeviceToken

但是现在我需要再次获取它，而我没有保存。 didRegisterForRemoteNotificationsWithDeviceToken仅调用一次，而其他时间应用仅运行registerUserNotificationSettings

我[NSUserDefaults standardUserDefaults]将所有新用户的令牌保存到[NSUserDefaults standardUserDefaults]但它仅适用于新用户。 与当前用户怎么办？

在“ didFinishLaunchingWithOptions”方法中添加以下代码...

if ([application respondsToSelector:@selector(registerUserNotificationSettings:)])
{
    [[UIApplication sharedApplication] registerUserNotificationSettings:[UIUserNotificationSettings settingsForTypes:(UIUserNotificationTypeSound | UIUserNotificationTypeAlert | UIUserNotificationTypeBadge) categories:nil]];
    [[UIApplication sharedApplication] registerForRemoteNotifications];
} 
else
{
    [[UIApplication sharedApplication] registerForRemoteNotificationTypes:
     (UIRemoteNotificationTypeBadge | UIRemoteNotificationTypeSound | UIRemoteNotificationTypeAlert)];
}

然后，在应用启动过程中，每次“ didFinishLaunchingWithOptions”调用都会调用“ didRegisterForRemoteNotificationsWithDeviceToken”方法。
