constraint(lessThanOrEqualToConstant:)
Returns a constraint that defines the maximum size for the anchor’s size attribute.
Declaration
func constraint(lessThanOrEqualToConstant c: CGFloat) -> NSLayoutConstraintParameters
- c:
A constant representing the maximum size of the attribute associated with this dimension anchor.
Return Value
An NSLayoutConstraint object that defines a maximum size for the attribute associated with this dimension anchor.
Discussion
This method defines the relationship first attribute <= c. Where first attribute is the layout attribute represented by the anchor receiving this method call.
The constraints produced by the following two examples are identical.
