Returns a view used to satisfy last baseline constraints.
- iOS 9.0+
- tvOS 9.0+
For views with multiple rows of text, the last baseline is the baseline for the bottommost row.
When you make a constraint to a view’s
NSLayout attribute, Auto Layout uses the baseline of the view returned by this method. If that view does not have a baseline, Auto Layout uses the view’s bottom edge.
Override this property to return a text-based subview (for example,
UILabel or a nonscrolling
UIText). The returned view must be a subview of the receiver. The default implementation returns the receiving view.
