Declaration
func constraint(greaterThanOrEqualTo anchor: NSLayoutParameters
anchorA dimension anchor from a
UIView,NSView, orUILayoutobject.Guide mThe multiplier constant for the constraint.
Return Value
An NSLayout object that defines the attribute represented by this layout anchor as greater than or equal to the attribute represented by the anchor parameter multiplied by the m constant.
Discussion
This method defines the relationship first attribute >= m * second attribute. Where first attribute is the layout attribute represented by the anchor receiving this method call, and second attribute is the layout attribute represented by the anchor parameter.
The constraints produced by the following two examples are identical.
// Creating a constraint using NSLayoutConstraint
NSLayoutConstraint(item: saveButton,
attribute: .Width,
relatedBy: .GreaterThanOrEqual,
toItem: cancelButton,
attribute: .Width,
multiplier: 2.0,
constant: 0.0).isActive = true
// Creating the same constraint using constraintGreaterThanOrEqualToAnchor:multiplier:
saveButton.widthAnchor.constraintGreaterThanOrEqualToAnchor(cancelButton.widthAnchor, multiplier: 2.0).isActive = true
