title: Adding resource files to xcode
body: <p>I'm trying to add some new resource files to a project which was build by another person on another mac. I think that the project has the provision of the previous person. </p>
  
  <p>Using right click->Add Files to "MyProject" doesn't provide the expected result. After I compile the project, the added file is not visible in the application.</p>
  
  <p>How can I add new resources in my project?</p>
  
  <p>PS: I'm trying to learn <code>Objective-C</code> in a <code>macincloud.com</code> account.</p>
