In my app, i need to put some boxes and make sure first two of them divided equally.
Navigation bar + status bar holds 64 point. Fixed height constraint of 60 point set to welcome box. Fixed height constraint of 145 point set to brown box. Tabbar holds 50 point.
Rest of the height which is 417 point should be divided into two. Green and Red boxes has its scrollviews in themselves. Scrollviews has layout constraint of same height, top, bottom, leading and trailing constraint for that of its superview. After layout is done, i inspected that red box has height of 208.66667 and green box has 208.3333. But each scroll views have height of 208.6667. So the scroll view at green box becomes vertically scrollable because its height(contentSize height) is bigger than that of its superview.
