== The UICollectionViewCell Class ==
<googlehtmlet>ADSDAQBOX_FLOWadsdaqbox_flow</googlehtmlet>
As the name suggests, the UICollectionViewCell class is responsible for displaying whatever data is provided to the UICollectionView instance by the data source with one cell corresponding to one data item. In terms of architecture, this class consists of two background views and one content view. The two background views may be used to provide a visual cue to the user when the corresponding cell is selected or highlighted. The content view contains the objects necessary to display the data to the user and can consist of any combination of valid UIKit classes. When adding subviews to a cell it is imperative that those objects be added to the contentView and not the background views, otherwise the objects will not be visible to the user.
