How to add Buttons in UIScrollView ?

[Ammad]

Hi,

I want to add buttons in UIScrollView, I'm confuse w.r.t syntax because I'm new in iPhone Dev.
I want to know that Should I add all buttons explicitly from Interface Builder? Or I can just put one UIButton in the UIScrollView in display no. of buttons through loop ?
Every button has its own function and has different image on it.
Please help.

Thanks in advance.
