title: Problems with IAP - no products in response.products array
body: <p>I have problem with In-App Purchase. After sending request to the server there are no products returned by <code>SKProductsRequest</code>.</p>
  
  <p>I send the request like this way:</p>
  
  <pre><code>    NSMutableSet *identificators = [[NSMutableSet alloc] init];
      [identificators addObject:kInAppPurchaseOneWeekIdentifier];
      [identificators addObject:kInAppPurchaseOneMonthIdentifier];
      [identificators addObject:kInAppPurchaseSixMonthsIdentifier];
  
      SKProductsRequest *request = [[SKProductsRequest alloc] initWithProductIdentifiers:identificators];
      request.delegate = self;
      [request start];
  
      [identificators release];
  </code></pre>
  
  <p>In Consts.h I have those</p>
  
  <pre><code>// In App Purchase
  #define kInAppPurchaseOneWeekIdentifier              @"com.astroboxapp.iap.OneWeek"
  #define kInAppPurchaseOneMonthIdentifier             @"com.astroboxapp.iap.OneMonth"
  #define kInAppPurchaseSixMonthsIdentifier            @"com.astroboxapp.iap.SixMonths"
  </code></pre>
  
  <p>In my class I've implemented</p>
  
  <pre><code>-(void)productsRequest:(SKProductsRequest *)request didReceiveResponse:(SKProductsResponse *)response {
  
      if ( [response.products count] &gt; 0 ) {
       // i've do my stuff - show the IAP to the user
      } else {
       // here goes the error handling
      }
  
  }
  </code></pre>
  
  <p>In my case <code>[response.products count]</code> is empty array/dictionary so i 
  throw an error.</p>
  
  <p>EDIT: What i have done ?</p>
  
  <ol>
  <li><p>I created a new IAP's and associate them with my app, I've changed the Products IDs too and change them in my Consts.h</p></li>
  <li><p>I've tried to change the app version from 1.0 to 1.1 somehow that help me to change the IAP for this version.</p></li>
  <li><p>Still not working on my device, while in the simulator there are entries for my IAP but i can test - because of StoreKit don't allow to test purchase from the sumulator.</p></li>
  <li><p>On my device I'am sign out from the store.</p></li>
  </ol>
