ios - 如何在 QuickBlox 中创建临时用户？

Question

我一直在寻找创建用户并在 session 结束后将其删除的最佳方式。我正在尝试进行匿名聊天。该应用程序创建随机登录名和密码，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)时，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)applicationWillTerminate:(UIApplication *)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，如果我将 IBAction 与它工作的相同代码放在一起。

有什么想法吗？

Answer 1

这是文档所说的:

(...) 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.
