Get server time through afnetworking

On some occasions, we need to obtain the server time, calculate the time and the client local time difference, in order to facilitate time synchronization. Some people say, this is not very simple, let the background of the TX give you a server time to get the interface on the line.

In fact, this is still more troublesome, it is easier to use the HTTP header to get the server time-the date parameter of each HTTP header is this time. In iOS we usually use afnetworking to send requests, so how to get HTTP header information with afnetworking?

Very simple, with [[Operation Response] allheaderfields] on the line.
