I read many post of contentview in scrollview,but the problem is slightly different.check out the image

and i have following hierarchy

Here the label is multiline label and its fill up with too many content size.
so, the problem is
1. according to the lines of the label, height of label changes and
2. accoring to height of label, contentview height changes.
so, that it scrolls. and i want this things to be done with autolayout.
And one thing i want to mention is , i'm using ios 8.1 and xcode 6.1
