title: I need to create separate file for all the constants of my project
body: <p>In my project I have a requirement to create separate file for all constants that i am using in separate classes in the same project.</p>
  <p>I seen some examples but they are saying about creating in '.h' file and again they are implementing them in '.m' files. But i need only '.h'file to create all constants and i have to use all those constants by importing that '.h' file in every class of my project.</p>
