This is my ViewController in the storyboard:

UIView (Controller)
-UIScrollView
--UIView
--UIView
--ContainerView
---UITableView (Embedded inside ContainerView)

The UITableView has dynamic prototypes.
My question is how do I change the UIScrollView and ContainerView's height to adapt to the UITableView's number of rows?

I want to be able to scroll down with my UIScrollView(not the UITableView's UIScrollView), when there are many rows inside the UITableView.

You can apply below logic to increase the height of scroll view.

height = Total number of rows (array or dictionary count) * your cell height (cell height should be static).

Using below calculation you will find the total height and set this height as a table height or scroll view height.

[scrollview setContentSize:CGMakeSize(scrollview.contentSize.width,tableView.frame.size.height)];

OR

[scrollview setContentSize:CGMakeSize(scrollview.contentSize.width,height)];

I hope this is work for you.

Thanks

Just update the contentSize of the UIScrollView every time there is a change in the number of rows.

Look at the example below:

- (void)updateScrollViewContentSize
{
    float cellHeight = 40;
    int numberOfRows = [noOfItemsInArray count];

    float sizeOfContent = cellHeight * numberOfRows;

    scrollView.contentSize = CGSizeMake(scrollView.frame.size.width, sizeOfContent);
}
