Create(NSObject, NSLayoutAttribute, NSLayoutRelation)

Factory method to create a constraint based on a UIView, an NSLayoutAttribute, and an NSLayoutRelation.

public static UIKit.NSLayoutConstraint Create(Foundation.NSObject view1, UIKit.NSLayoutAttribute attribute1, UIKit.NSLayoutRelation relation);

static member Create : Foundation.NSObject * UIKit.NSLayoutAttribute * UIKit.NSLayoutRelation -> UIKit.NSLayoutConstraint

Parameters

view1: NSObject

The view or object in the constraint.

attribute1: NSLayoutAttribute

The attribute for the view.

relation: NSLayoutRelation

The relationship in the constraint.

Returns

NSLayoutConstraint

A new constraint with the specified parameters and default multiplier (1.0) and constant (0.0).

Remarks

Creates a constraint for a single view with default multiplier and constant values.

Applies to

Create(NSObject, NSLayoutAttribute, NSLayoutRelation, NFloat, NFloat)

Factory method for creating a constraint.

public static UIKit.NSLayoutConstraint Create(Foundation.NSObject view1, UIKit.NSLayoutAttribute attribute1, UIKit.NSLayoutRelation relation, System.Runtime.InteropServices.NFloat multiplier, System.Runtime.InteropServices.NFloat constant);

static member Create : Foundation.NSObject * UIKit.NSLayoutAttribute * UIKit.NSLayoutRelation * System.Runtime.InteropServices.NFloat * System.Runtime.InteropServices.NFloat -> UIKit.NSLayoutConstraint

Parameters

view1: NSObject

The view or object in the constraint.

attribute1: NSLayoutAttribute

The attribute for the view.

relation: NSLayoutRelation

The relationship in the constraint.

multiplier: NFloat

The multiplier applied to the attribute.

constant: NFloat

The constant value in the constraint.

Returns

NSLayoutConstraint

A new constraint with the specified parameters.

Remarks

Creates a constraint for a single view with a specified attribute, relation, multiplier, and constant value.

Applies to

Create(NSObject, NSLayoutAttribute, NSLayoutRelation, NSObject, NSLayoutAttribute, NFloat, NFloat)

Factory method for creating a constraint.

public static UIKit.NSLayoutConstraint Create(Foundation.NSObject view1, UIKit.NSLayoutAttribute attribute1, UIKit.NSLayoutRelation relation, Foundation.NSObject view2, UIKit.NSLayoutAttribute attribute2, System.Runtime.InteropServices.NFloat multiplier, System.Runtime.InteropServices.NFloat constant);

public static UIKit.NSLayoutConstraint Create(Foundation.NSObject view1, UIKit.NSLayoutAttribute attribute1, UIKit.NSLayoutRelation relation, Foundation.NSObject? view2, UIKit.NSLayoutAttribute attribute2, System.Runtime.InteropServices.NFloat multiplier, System.Runtime.InteropServices.NFloat constant);

static member Create : Foundation.NSObject * UIKit.NSLayoutAttribute * UIKit.NSLayoutRelation * Foundation.NSObject * UIKit.NSLayoutAttribute * System.Runtime.InteropServices.NFloat * System.Runtime.InteropServices.NFloat -> UIKit.NSLayoutConstraint

Parameters

view1: NSObject

First view in the constraint.

attribute1: NSLayoutAttribute

Attribute for the first view.

relation: NSLayoutRelation

Relationship between the view1 and the view2.

view2: NSObject

Second view in the constraint. This parameter can be null.

attribute2: NSLayoutAttribute

Attribute for the second view.

multiplier: NFloat

Multiplier applied to the second attribute.

constant: NFloat

Constant to add.

Returns

NSLayoutConstraint

A new constraint with the specified parameters.

Remarks

Creates a constraint relationship between the view1 and the view2 that satisfies the following linear equation: attribute1 = multiplier x attribute2 + constant.

Applies to

Create(INativeObject, NSLayoutAttribute, NSLayoutRelation, INativeObject, NSLayoutAttribute, NFloat, NFloat)

Factory method for creating a constraint.
