title: Different treatment of %d in ObjectiveC versus iOS
body: <p>1st question here. Reviewed FAQ but did not find answer.</p>
  
  <p>I learned Obj C using Kochan book and he classifies %i for integers, %f for float, %d for double.</p>
  
  <p>Using iOS, it seems that it is rather: %i and %d for integer and %f for float</p>
  
  <p>Can someone confirm and maybe explain the rationale. I already looked through the string programming guide of Apple.</p>
  
  <p>Thank you in advance.</p>
