从Apple Server获取日期和时间 [英] Get Date and Time from Apple Server

问题描述

我正在开发一个只能在一天中的特定时间使用的应用程序.我无法获取本地设备时间，因为用户可以轻松更改设备时间，从而可以在一天中的任何时间访问应用程序.

I'm developing an app that can only be used during a certain time of the day. I can't get the local device time because the user can easily change the device time thereby allowing access to the application for any time of the day.

有没有办法从Apple服务器获取当前日期和时间(如果没有的话)还有其他方法吗?

Is there a way to get the current date and time from an Apple server (or if not,) is there any other way?

推荐答案

我认为您应该使用Internet时间服务器.他们正在使用称为 NTP 的标准化协议. iOS具有内置支持，可读取NTP服务器时间，但这无法访问作为应用程序开发人员.您可以自己实现，也可以使用开放源代码库，例如 ios-ntp 或 HS NTP .我本人还没有使用过它们.检查设备的位置并找出时区，以获得真正的防弹解决方案可能是个好主意.

I think that you should be using an Internet time server. They are using a standardized protocol called NTP. The iOS has built-in support for reading NTP server time, but this is not accessible to you as an application developer. Either you implement this yourself, or you could maybe use an open source library, like ios-ntp or HS NTP. I have not used any of them myself. It is probably a good idea to check the position of the device and figure out the timezone, to get a real bulletproof solution.

理想情况下，您应该在应用程序中具有服务器列表.如果其中一个失败，则调用列表中的下一个NTP服务器.

Ideally, you should have a list of servers in the application. If one of them fails, you call the next NTP server in the list.
