title: Compiler Warnings with AFHTTPclient
body: <p>I am a newbie to AFNetworking and running a simple application to understand how AFNetworking is working. I am following this tutorial on MobileTuts: <a href="http://mobile.tutsplus.com/tutorials/iphone/ios-sdk_afnetworking/">http://mobile.tutsplus.com/tutorials/iphone/ios-sdk_afnetworking/</a>. I am able to get the app running with the information but I have these two warnings.</p>
  
  <p>The two warnings are:</p>
  
  <ol>
  <li>#warning "SystemConfiguration framework not found in project, or not included in precompiled header. Network reachability functionality will not be available."</li>
  </ol>
  
  <p>2.#warning "CoreServices framework not found in project, or not included in precompiled header. Automatic MIME type detection when uploading files in multipart requests will not be available."</p>
  
  <p>I have already included the SystemConfiguration and CoreServices framework but these warnings still exist...</p>
