The scrolling of an any scroll view is totally depends on the contentSize property. Here in your code you have not mentioned the content size for your scrollView1.

So, you should add this,

scrollView1.contentSize = CGSizeMake(700, 1750);

Here we provided two parameters one is width and other is height. This gives 10 times vertical scrolling because your frame height is of 175 pixels and contentSize height is of 1750 pixels.

Note : Your contentSize values i.e. width and height must be greater than frame size for scrolling purpose.

Thank you...

The scrolling of a UIScrollView is based on the contentSize property, which is a CGSize value.

Whenever the width or height are bigger than the scroll view frame, the scroll view will allow the scrolling (if the properties showsVerticalScrollIndicator, showsHorizontalScrollIndicator and scrollEnabled are all set to YES - which are the default values)

So, one thing that you can try to do is setting the height of your contentSize bigger than the one already set as your frame, for example:

scrollView1.contentSize = CGSizeMake(700, 300);

Also check your autoRotate function is returning the correct layout. If you have do not tell your application that it can rotate view to portrait, then it will stay in the horizontal configuration, which you have hardcoded.
