  <p>I tried following but still the problem persists? Appreciate any help.</p>
  
  <ol>
  <li>Removed "<code>NSObject+SBJSON.m</code>" and "<code>NSString+SBJSON.m</code>" files and added back to Compile sources of Build Phases.</li>
  <li>Added i386 for Valid Architecures in Build Settings.</li>
  <li>Tried with <code>-all_load</code> linker flag </li>
  </ol>
