A nice tray to show items at the bottom of an iOS screen. It's best used in combination with a table view that allows for multiple items to be selected. For example, in this list from the app deci, a user can select their Facebook friends to invite to collaborate on a social decision. For each person that is selected from the table, their Facebook profile picture is added to the AOTrayView. The avatar pops in or out with a nice animation. Once more avatars are added to the tray view than can fit horizontally, the AOTrayView allows for the user to scroll side to side to see them.

Used in the app deci.
