forBaselineLayout()

Declaration

func forBaselineLayout() -> UIView

Return Value

The view the constraint system should use to satisfy baseline constraints

Discussion

When you make a constraint to a view’s NSLayoutAttributeBaseline 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 method to return a text-based subview (for example, UILabel or a nonscrolling UITextView). If you override this method, the returned view must be a subview of the receiver. The default implementation returns the receiving view.
