Question

I want to define a string variable which holds an IP Address globally,so that if in future the IPAddress got changed no need to go to each class file & update it, So for this what is the best way to implement whether to use plist or a global macro class or .pch file of my app?

Answer 1

Create a .h file. Say, GlobalMacros.h

In GlobalMacros.h

#define IP_ADDR @“SERVER_IP”

In your .pch file

import “GlobalMacros.h”

Now you can simply access the IP_ADDR anywhere.
