Hi Tharindu.
I would create two files: Constants.h and Constants.m. Just like all C code, you put your declarations in the .h and the definitions in the .m. They are going to be very similar, except the .m defines the values, so it only happens once. This is very important if you want to be able to compare NSString constants using pointer equality. You then have all of your other code import Constants.h
--------- Constants.h ---------------
extern const int Foo;
extern const float Bar;
extern const NSString *Suction;
--------- Constants.m ---------------
const int Foo = 42;
const float Bar = 4.2;
const NSString *Suction = @"Ball";
