Public Methods

Method Description
ConstrainLayout ( this view, Expression constraints ) : NSLayoutConstraint[]

Constrains the layout of subviews according to equations and inequalities specified in constraints. Issue multiple constraints per call using the && operator.

e.g. button.Frame.Left >= text.Frame.Right + 22 && button.Frame.Width == View.Frame.Width * 0.42f
ConstrainLayout ( this view, Expression constraints, UILayoutPriority priority ) : NSLayoutConstraint[]

Constrains the layout of subviews according to equations and inequalities specified in constraints. Issue multiple constraints per call using the && operator.

e.g. button.Frame.Left >= text.Frame.Right + 22 && button.Frame.Width == View.Frame.Width * 0.42f
GetBaseline ( this viewFrame ) : nfloat

The baseline of the view whose frame is viewFrame. Use only when defining constraints.
GetCenterX ( this viewFrame ) : nfloat

The x coordinate of the center of the frame.
GetCenterY ( this viewFrame ) : nfloat

The y coordinate of the center of the frame.

Method Details

ConstrainLayout() public static method

Constrains the layout of subviews according to equations and inequalities specified in constraints. Issue multiple constraints per call using the && operator.

e.g. button.Frame.Left >= text.Frame.Right + 22 && button.Frame.Width == View.Frame.Width * 0.42f

public static ConstrainLayout ( this view, Expression constraints ) : NSLayoutConstraint[]
view this The superview laying out the referenced subviews.
constraints Expression Constraint equations and inequalities.
return NSLayoutConstraint[]

ConstrainLayout() public static method

Constrains the layout of subviews according to equations and inequalities specified in constraints. Issue multiple constraints per call using the && operator.

e.g. button.Frame.Left >= text.Frame.Right + 22 && button.Frame.Width == View.Frame.Width * 0.42f

public static ConstrainLayout ( this view, Expression constraints, UILayoutPriority priority ) : NSLayoutConstraint[]
view this The superview laying out the referenced subviews.
constraints Expression Constraint equations and inequalities.
priority UILayoutPriority The priority of the constraints
return NSLayoutConstraint[]

GetBaseline() public static method

The baseline of the view whose frame is viewFrame. Use only when defining constraints.
public static GetBaseline ( this viewFrame ) : nfloat
viewFrame this
return nfloat

GetCenterX() public static method

The x coordinate of the center of the frame.
public static GetCenterX ( this viewFrame ) : nfloat
viewFrame this
return nfloat

GetCenterY() public static method

The y coordinate of the center of the frame.
public static GetCenterY ( this viewFrame ) : nfloat
viewFrame this
return nfloat
