What does “Constrain to margins” mean in Interface Builder in Xcode 6.0.1

Question

I understand the purpose of \"Spacing to the nearest neighbor\" (in Xcode 6, more especially in Interface Builder) but what is the point of \"Constrain to margins\"?

Answer 1

iOS8 introduces a new property of the UIView: layoutMargins. Shortly: these 4 values (a UIEdgeInsets) represent the margins of the view: its subviews can now be positioned relative to these margins, or the old way relative to the sides. I wrote an article about this in my blog with more details, let me know if it is clear and if you have additional doubts.
