The current solution is to add a sub view for panel to the main view, And the sub view is used as a view container to include the view to be displayed in the panel, then, you can use animation to implement view switching.

Several notes:

1. How to hide a panel outside the dot panel by using a dimming layer (uiview or uiimageview)

2. Use animation to simulate the effect of navigation controller to switch views.

Note: by default, sub View B in uiview A is displayed if the position of sub View B is outside the bound of uiview. If it is not displayedClipstoboundsProperty set to yes. (Ref link: http://hi.baidu.com/marktian/blog/item/395adc24e7b39d2ec995597f.html)
