title: Cannot find protocol declaration for RKObjectLoaderDelegate xCode 4.6
body: <p>I am facing a RestKit error while implementing iOS application. Telling Cannot find protocol declaration for <code>RKObjectLoaderDelegate</code> or <code>RKRequestDelegate</code>.<br>
  And if I add <code>#import &lt;RKObjectLoader.h&gt;</code> it tells file not found.  </p>
  
  <p>How could I solve this? Is there anything missing?</p>
  
  <p>I am using Restkit 0.20.0 and i imported Restkit using the following guide <a href="https://github.com/RestKit/RestKit/wiki/Installing-RestKit-in-Xcode-4.x" rel="nofollow">https://github.com/RestKit/RestKit/wiki/Installing-RestKit-in-Xcode-4.x</a></p>
  
  <p>and i am getting use of undeclared identifier on <code>RKURL</code>. and i am importing <code>#import &lt;Restkit\Restkit.h&gt;</code> in the header file of each view.</p>
  
  <p>my class implements the following <code>@interface TrackingMapViewCOntroller : UIViewController &lt;MapViewDelegate, UITextFieldDelegate, RKObjectLoaderDelegate&gt;</code></p>
