Reloading the collectionView datasource with out any delay.

[praveenkokkula712]

In the provided demo project, you have updated the collection view cell as per the static model. but if I want to pass the data to the collection view from any complicated which requires some filter and sort option. It is giving me some delay while loading the collection view datasource.

How can you achieve this, is there any way we can pass some dummy data till we get the actual data to the collection view.
