ios - 如何在 QuickBlox 中创建临时用户？

我正在寻找创建用户并在 session 结束后将其删除的最佳方法。我正在尝试进行匿名聊天。应用程序创建和随机登录名和密码，注册用户并登录。当用户关闭应用程序(双击主页并向上滑动)它应该删除用户。

我应该把 [QBUsers deleteUserWithID:userID delegate:self] 放在哪里；代码？

我已经在 applicationWillTerminate 中尝试过:

- (void)applicationWillTerminateUIApplication *)application {
    [QBUsers deleteUserWithID:appDelegate.appUser.userID delegate:self];
    NSLog(@"%u",appDelegate.appUser.userID);  
}

NSLog 返回正确的 ID，但用户不会被删除，如果我使用相同的代码放置 IBAction 即可。

有什么想法吗？

文档是这样说的:

(...) you must be prepared for your app to be killed without any notification. The user can kill apps explicitly using the multitasking UI.

还有一些关于 applicationWillTerminate 的更多信息:

If your app is running at termination time, the system calls your app delegate’s applicationWillTerminate: method so that you can perform any required cleanup. Your method has approximately 5 seconds to perform any tasks and return. If it does not return in time, the app is killed and removed from memory.

Important: The applicationWillTerminate: method is not called if your app is currently suspended.
