Answer 1

To change the size of scroll view

scrollView.frame = CGRectMake(originX, originY, width, height);

to change the size of scrollable area:

scrollView.contentSize = CGSizeMake(width, height);

Swift 3 version

scrollView.frame = CGRect(x: scrollX, y: scrollY, width:width, height:height)

scrollView.contentSize = CGSize(width:width, height: height)

Answer 2

trigger any function when you need to increase your scrollview then use this code in that function and make your desired size for scrollview

scrollViewName.frame = CGRectMake(originX, originY, width, height);

change scrollable area

scrollViewName.content.size = CGSizeMake(width, height);...

Answer 3

int height = 600;
for (i = 0; i<5; i++)
{
  // do what you want. suppose you create a view which size is - 10,10,300,800.

  height = createdView.frame.size.height+10;
}

scrollView.contentSize = (320, height);

Hope this will help you.
