objective c - How to set the date and time programmatically in iOS

Question

I have a requirement in which we need to programmatically set the date and time (or sync the time) from a server.

How is it done in iOS?

Is there any Apple documentation which says we cannot do this?

Answer 1

You can't set the date and/or time on iPhone/iPad programmatically. Those APIs are considered protected by Apple. In other words if you were to use those APIs and submit an app using them it would be rejected.

Edit:

To get documentation on this you can contact Apple Developer Technical Support using one of your free tech support incidents included with your developer program. LINK
