Instance Property


Returns a view used to satisfy first baseline constraints.


var forFirstBaselineLayout: UIView { get }


For views with multiple rows of text, the first baseline is the baseline for the topmost row.

When you make a constraint to a view’s firstBaseline 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 top edge.

Override this property to return a text-based subview (for example, UILabel or a nonscrolling UITextView). The returned view must be a subview of the receiver. The default implementation returns the value contained by forLastBaselineLayout.
