simple IOS xcode game

I need to write game within 48 [login to view URL] attached screenshot for idea. I'll post complete details in chat. The Picker The top part of the game will be a picker with 5 components. Each component displays the values 1 through to 5. The Rules If a component rolls down, i.e. - displays a higher value, then the components on either side will move down by the same amount. If component 1 is selected then components 2 and 5 will move. If component 5 is selected then components 1 and 4 will move. If the amount moved causes a component to be moved to a higher value than it can display then it will wrap around. The same goes if the component is moved to a lower value than it can display.
