title: Objective-C: Importing headers in .h or .m?
body: <p>I'm new to objective-c and would like to know the best practice for importing some external headers that I use in my class.</p>
  
  <p>Should I be storing the #import "classB.h" in my own classes .h file or in the .m file?</p>
  
  <p>What's the difference?</p>
  
  <p>Thanks!</p>
