How to know whether can move to left,right,up,down  about  UIScrollView?
Means whether reached the border (left,right,up,down)
I know the "canMoveVertically", but i don't know up or down.

UIPanel has functions for that -- CalculateConstrainOffset. You pass it the min/max of the content (NGUITools.CalculateRelativeWidgetBounds), and it will give you the offset required to offset the panel to make everything fit. If you need more details, just look inside the function for the math involved and create something similar.
