Adds a view to a stack view gravity area at a specified index position.
- macOS 10.9+
The view to add to the specified gravity area.
The index position, within the gravity area, for the new view. The position of index
0depends on the stack view layout direction and, for a horizontal stack view, on the user interface layout direction:
0index for a gravity area is at the leading side, as determined by the value of the inherited
userproperty of the stack view. For a left to right language, index
Interface Layout Direction
0is at the left of the gravity area.
0index for a gravity area is at the top.
The gravity area that you are adding the specified view to. Valid values are those in the
Calling this method updates the stack view’s layout, which can change the stack view size. As a result, views could detach or clip according to the clipping resistance of the stack view and the visibility priorities of its views.
A view in a detached state is not present in the stack view’s view hierarchy, but it still consumes memory. To respond to detachment and reattachment of views, implement an
NSStack object and assign it to the
