Instance Method

scaleUnitSquare(to:)

Scales the view’s coordinate system so that the unit square scales to the specified dimensions.

Declaration

func scaleUnitSquare(to newUnitSize: NSSize)

Parameters

newUnitSize

An NSSize structure specifying the new unit size.

Discussion

For example, a newUnitSize of (0.5, 1.0) causes the view’s horizontal coordinates to be halved, in turn doubling the width of its bounds rectangle. Note that scaling is performed from the origin of the coordinate system, (0.0, 0.0), not the origin of the bounds rectangle; as a result, both the origin and size of the bounds rectangle are changed. The frame rectangle remains unchanged.

This method does not redisplay the view or mark it as needing display. You must do this yourself by calling the display() method or setting the needsDisplay property.

This method posts an boundsDidChangeNotification to the default notification center if the view is configured to do so.

func rotate(byDegrees: CGFloat)

Rotates the view’s bounds rectangle by a specified degree value around the origin of the coordinate system, (0.0, 0.0).
