title: Do you put #import s in .h or .m files?
body: <p>I wonder about Objective-C style.</p>
  
  <p>I have FooClass.[hm] that depends on BarClass.[hm] for its implementation (though not for its interface). I can <code>#import "BarClass.h"</code> either directly in FooClass.m or indirectly through FooClass.h. I wonder about the common choice for this.</p>
