Why not just use the autoresizingMask to bind your image view to the size of its parent views? Then all you need to do (potentially) is determine if you want to display the correct image for landscape or portrait. No need to manually fiddle with the frame or bounds of the view at all (unless you want to do more complex orientation, in which case go for it). But the coordinate systems are relatively simple. The frame is your view's coordinate system in its parent's coordinate system (that is, where you are in the world). The bounds is your view's coordinate system in its own coordinate system (that is, what is the extent of your world). It doesn't make sense to set your frame in terms of your parent's frame, because that is the wrong coordinate system – that would be like trying to locate your house in terms of the Earth's location in the Solar System. You can do it, but it is hard and there are much easier ways to go about the task. -- David Duncan Apple DTS Animation and Printing _______________________________________________ Cocoa-dev mailing list ([email protected]) Please do not post admin requests or moderator comments to the list.
