public class LayoutAnchor<AnchorType: AnyObject> 

Methods

constraint(equalTo:)

Returns a constraint that defines one item’s attribute as equal to another.

public func constraint(equalTo anchor: LayoutAnchor<AnchorType>)
      -> LayoutConstraint 

constraint(equalTo:constant:)

Returns a constraint that defines one item’s attribute as equal to another item’s attribute plus a constant offset.

public func constraint(equalTo anchor: LayoutAnchor<AnchorType>,
                         constant offset: Double) -> LayoutConstraint 

constraint(greaterThanOrEqualTo:)

Returns a constraint that defines one item’s attribute as greater than or equal to another.

public func constraint(greaterThanOrEqualTo anchor: LayoutAnchor<AnchorType>)
      -> LayoutConstraint 

constraint(greaterThanOrEqualTo:constant:)

Returns a constraint that defines one item’s attribute as greater than or equal to another item’s attribute plus a constant offset.

public func constraint(greaterThanOrEqualTo anchor: LayoutAnchor<AnchorType>,
                         constant offset: Double) -> LayoutConstraint 

constraint(lessThanOrEqualTo:)

Returns a constraint that defines one item’s attribute as less than or equal to another.

public func constraint(lessThanOrEqualTo anchor: LayoutAnchor<AnchorType>)
      -> LayoutConstraint 

constraint(lessThanOrEqualTo:constant:)

Returns a constraint that defines one item’s attribute as less than or equal to another item’s attribute plus a constant offset.

public func constraint(lessThanOrEqualTo anchor: LayoutAnchor<AnchorType>,
                         constant offset: Double) -> LayoutConstraint
