title: iOS in app-purchase receipt validation - sandbox vs production url?
body: <p>I followed <a href="http://www.raywenderlich.com/23266/in-app-purchases-in-ios-6-tutorial-consumables-and-receipt-validation" rel="nofollow noreferrer">Ray Wenderlich's tutorial</a> to implement receipt validation in my app.  The code connects to Apple's validation server directly from my app rather than going through my own server.</p>
  
  <p>After I submitted my first binary to the AppStore, I tested my app and the in-app purchasing didn't work because I had switched it over from the sandbox URL to the production URL.</p>
  
  <p>Will this also fail when they AppStore reviewers test it and therefore be rejected?  I've read <a href="https://stackoverflow.com/questions/11739576/ios-in-app-purchase-will-apple-reviewers-test-live-or-sandbox-environment/11740575#11740575">this post</a> but I'm still very confused about whether that applies to me if I'm not using my own server.</p>
