Instance Property

splitView

The split view managed by the split view controller.

Declaration

var splitView: NSSplitView { get set }

Discussion

This property gives you access to the split view controller’s split view, for querying its attributes or customizing it in certain ways.

By default, a split view is configured with horizontal dividers so that child views are arranged vertically, from top to bottom in the split view controller’s view. To specify horizontal (side-by-side) arrangement of child views, implement the vertical property of the NSSplitView object to return true.

Also by default, a split view has a divider style of NSSplitView.DividerStyle.thin, and does not have an auto-save name.

To provide a custom split view, set this property at any time before you call super in the inherited viewDidLoad() method; that is, before the split view controller’s isViewLoaded property is true.

The split view is not guaranteed to be the same object as that in the split view controller’s inherited view property. To access the split view, always use the splitView property.
