title: Restkit integration into iOS project
body: <p>I have a problem during the import of Restkit Framework into my iOS project.
  I followed this tutorial: <a href="http://www.raywenderlich.com/13097/intro-to-restkit-tutorial" rel="nofollow">Intro to RestKit Tutorial</a></p>
  
  <p>I followed step by step the tutorial about Restkit integration but when I try to build I have always this error:</p>
  
  <p>/myAPPDirectory/RestKit/Code/ObjectMapping/RKObjectMapping.h:23:9: 'RKValueTransformers.h' file not found</p>
  
  <p>I have the same error also when I try to build a Restkit integrated example project.</p>
  
  <p>I use Xcode 5.</p>
