You can use
UICollection as-is or subclass it to add additional properties and methods. The layout and presentation of cells is managed by the collection view and its corresponding layout object.
To configure the appearance of your cell, add the views needed to present the data item’s content as subviews to the view in the
content property. Do not directly add subviews to the cell itself. The cell manages multiple layers of content, of which the content view is only one. In addition to the content view, the cell manages two background views that display the cell in its selected and unselected states.
You typically do not create instances of this class yourself. Instead, you register your specific cell subclass (or a nib file containing a configured instance of your class) with the collection view object. When you want a new instance of your cell class, call the
dequeue method of the collection view object to retrieve one.
