+The `LMAnchorView` class optionally anchors subviews to one or more of its own edges. Although it is possible to achieve similar layouts using a combination of row, column, and spacer views, anchor views offer a simpler alternative in some cases. Anchor views are also the only layout container that supports Z-ordering. 
 
 Anchors are specified as an option set that defines the edges to which the view will be anchored within its parent. For example, the following code creates an anchor view containing four labels anchored to its top, left, right, and bottom edges. The labels will all be inset by 16 pixels:
