Which is best if I wanted Page based design?

Which one is good to use for a page based design, Pageviewcontroller or UIScrollview with paging.

Which will consume less memory? I have done it via UIScrollview; but it's consuming very huge memory. Any help will be greatly appreciated.

Using UIScrollView for the application is not a handy task. For iOS 6, you should use UIPageViewController. But for iOS 5, UIPageViewController is not be good as it only provides scrolling for the page transition.

You may reuse the UIScrollView views then,

Many examples are there in SO like this

It is hard to say which is "best" - it depends on what makes sense for your app. Which ever approach you choose you can minimise memory consumption by "lazy loading" content into the scroll view when it is needed. For example, if you were displaying pages of images and the images are stored as files in your app then you should only add the current image and the image either side of the current image. As you scroll you can load and add the next image and release.

Here is a tutorial that shows this approach with UIScrollView- Multiple virtual pages in a UIScrollView with just 2 child views

UIPageViewController makes it a bit simpler by adopting a dataSource pattern, so you can concentrate on responding to data requests and not have to worry about manipulating the views.
