title: iOS test App Receipt Validation
body: <p>There is a lot of example about how to test in-app purchase receipt validation by using a sandbox tester account.</p>
  
  <p>But how is the Receipt for the paid App itself?  How can we get the App Receipt in development environment?</p>
  
  <p>There is two thing I want to do:</p>
  
  <ul>
  <li><p>To prevent illegal copy of our app running by the user who didn't purchase the app. 
  As I have seen app that detected the iTune Account was connected doesn't owned the app (it shows warning to the user they didn't own the app, but they fail to stop the user to continue to use the app)</p></li>
  <li><p>Send the app purchase receipt to our server.  We want to know when do they buy our app, what version of app they brought.</p></li>
  </ul>
