ios - 第二次获取ios push deviceToken

Question

我需要获取 deviceToken。当我向我的应用程序添加推送通知时，我通过 didRegisterForRemoteNotificationsWithDeviceToken

收到了 deviceToken

但现在我需要重新获取它，但我没有保存。didRegisterForRemoteNotificationsWithDeviceToken 只调用一次，其他时候应用只运行 registerUserNotificationSettings

我想将所有新用户的 token 保存到 [NSUserDefaults standardUserDefaults] 但它只适用于新用户。如何处理当前用户？

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“didRegisterForRemoteNotificationsWithDeviceToken”方法将在应用程序启动期间的每次调用“didFinishLaunchingWithOptions”时被调用。
