title: Add the Google APIs Client Library for Objective-C to Xcode project
body: <p>I'm trying to make an iPhone application that use Google+ API. I found <a href="http://code.google.com/p/google-api-objectivec-client" rel="nofollow">http://code.google.com/p/google-api-objectivec-client</a></p>
  
  <p>Now, I'm trying to add this API im my Xcode project by drag and drop the source folder in API. I also linked static library in build phase of target. But after build of the project, lots of errors are there.</p>
  
  <p>Further, I found document for adding API to project from here <a href="http://code.google.com/p/google-api-objectivec-client/wiki/BuildingTheLibrary" rel="nofollow">http://code.google.com/p/google-api-objectivec-client/wiki/BuildingTheLibrary</a>. I followed the same steps but still getting error.</p>
