Dynamically set UIView size depending on height of grouped table view

Setup: I have a UIView with a scroll view nested within it. Within the scroll view I have a label, uiimage, and a tableview (grouped). The label, uiimage, and tableveiw are populated by a webservice. The last section in the grouped table view contains text that will never be the same and could be as long as 5 characters to 250+. Also, this view is pushed from a basic 开发者_如何转开发tableview (so it has a navigation bar. If that matters at all).

Expected: The uiview should extend in height depending on the height tableview extends to. Then I will be able to set the scrollview to accommodate the height I need to be able to scroll.

Problem: I'm not quite sure how to approach the issue. I really only know how to change the height to fixed values, which will not work properly in almost any scenario.

Am I using UIScrollView incorrectly? Do I need to resize the UIView at all?

You don't have to modify your UIView frame size, which has to be the size of your screen. The UIScrollView frame size must also be the same, it represents the part of its view actually displayed.

What must change is the UIScrollView contentSize, which defines height and width for data inside it ;)

You can calculate it using each inside element's height and by adding the correct margin. Thus, you could have a UIScrollView content size of 320 * 600, which will let you automatically scroll down.

In fact, you have to display your content independently of the final frame size. If you have a content of 500*500, just display it inside your UIScrollView. Then tell it the size of it's content, and it will automatically set scrolling possibilities if needed.

Turns out I had to create a UIView programmatically and set it as the header of the UITableView. It works perfectly now. :)
