Instance Property

layoutMargins

The default spacing to use when laying out content in the view.

Declaration

var layoutMargins: UIEdgeInsets { get set }

Discussion

In iOS 11 and later, use the directionalLayoutMargins property to specify layout margins instead of this property. When you assign a value to the directionalLayoutMargins property, the view uses the directional margin values to update the left and right margins in this property.

Use this property to specify the desired amount of space (measured in points) between the edge of the view and any subviews. Auto layout uses your margins as a cue for placing content. For example, if you specify a set of horizontal constraints using the format string “|-[subview]-|”, the left and right edges of the subview are inset from the edge of the superview by the corresponding layout margins. When the edge of your view is close to the edge of the superview and the preservesSuperviewLayoutMargins property is true, the actual layout margins may be increased to prevent content from overlapping the superview’s margins.

The default margins are eight points on each side.

If the view is a view controller’s root view, the system sets and manages the margins. The top and bottom margins are set to zero points. The side margins vary depending on the current size class, but can be either 16 or 20 points. You cannot change these margins.
