iOS - UIScrollView is not scrolling-- my solution

Scenerio:

tableview inside scrollview, scrollview inside view

1. view height=568

2. scrollview height= 568

3.tableview : scrolling enabled =unchecked

4.tableview :height=1100

5.

CGSize scrollViewContentSize = CGSizeMake(320, 1400);

[self.scroll setContentSize:scrollViewContentSize];

6. 

 Summary 1. tableview.y +tableview.height~=scroll contensize.height

 Summary 2.  scrollViewContentSize>scrollview.height=view.height
