View Coordinate Systems

Coordinates in UIKit are based on a coordinate system whose origin is in the top-left corner and whosecoordinate axes extend down and to the right from that point. Coordinate values are represented usingfloating-point numbers, which allow for precise layout and positioning of content and allow for resolutionindependence. Figure 2-3 (page 55) shows this coordinate system relative to the screen, but this coordinatesystem is also used by the UIWindow and UIView classes. This particular orientation was chosen to make it

easier to lay out controls and content in user interfaces, even though it differs from the default coordinatesystems in use by Quartz and Mac OS X.

As you write your interface code, be aware of the coordinate system currently in effect. Every window andview object maintains its own local coordinate system. All drawing in a view occurs relative to the view’slocal coordinate system. The frame rectangle for each view, however, is specified using the coordinate systemof its parent view, and coordinates delivered as part of an event object are specified relative to the coordinatesystem of the enclosing window. For convenience, the UIWindow and UIView classes each provide methods

to convert back and forth between the coordinate systems of different objects.

Although the coordinate system used by Quartz does not use the top-left corner as the origin point, for manyQuartz calls this is not a problem. Before invoking your view’s drawRect: method, UIKit automatically

configures the drawing environment to use a top-left origin. Quartz calls made within this environment drawcorrectly in your view. The only time you need to consider these different coordinate systems is when youset up the drawing environment yourself using Quartz.

For more information about coordinate systems, Quartz, and drawing in general, see “Graphics andDrawing” (page 85).

You still have to create durable

demand.









There is still lots of money being made.



Maybe the

iFairy didn’t retire.
