Hi,
We are checking the sample application (MyInventory) and it explored for TableView controller as well as CollectionView Controller.
But CollectionView Controller is not working on the MyInventory Sample.
But we have tried to load the collectionview inside viewcontroller and defined page header and footer.
Collection view shows only blank screen (black) while deploying in iOS emulator and we couldn't access the CollectionView Class properties.
Kindly let me know if you require sample app for CollectionView Controller.

Note: We are working from Core Project to support iOS and Android Platforms.
