Set Time Zone conversion for iOS

 

Sometimes, in order to unify the time in the system, the time zone that needs to be exchanged between the server and the client, for example, using GMT.
The code for converting an iPhone is as follows:

Nsdate * Now = [nsdate date];
Nslog (@ "% @", [now description]);
Nstimezone * defaulttimezone = [nstimezone defaulttimezone];
Nstimezone * tzgmt = [nstimezone timezonewithname: @ "GMT"];
[Nstimezone setdefatimetimezone: tzgmt];
Nslog (@ "% @", [now description]); // It is expressed by GMT.
[Nstimezone setdefatimetimezone: defaulttimezone]; // sets the default

Or:

[Nstimezone setdefatimetimezone: [nstimezone timezonewithabbreviation: @ "CMT"];
