Instance Method

addConstraints:

Adds multiple constraints on the layout of the receiving view or its subviews.

Declaration

- (void)addConstraints:(NSArray<NSLayoutConstraint *> *)constraints;

Parameters

constraints

An array of constraints to be added to the view. All constraints may only reference the view itself or its subviews.

Discussion

All constraints must involve only views that are within scope of the receiving view. Specifically, any views involved must be either the receiving view itself, or a subview of the receiving view. Constraints that are added to a view are said to be held by that view. The coordinate system used when evaluating each constraint is the coordinate system of the view that holds the constraint.
