First,create a CustomCell which is a subclass of UICollectionViewCell.. Then, import that CustomCell.h file into your collectionView's controller.
If you want to set up those properties on some cells, using the delegate method - (UICollectionViewCell *)cellForItemAtIndexPath:(NSIndexPath *)indexPath
If you want to set up those properties for all cells, just put them inside CustomCell.m.Remember import QuartzCore framework.
