Using hundreds of buttons seems a bit heavy-handed even for the Mac, let alone iPhone. Any kind of one-subview-per-seat solution seems undesirable. Even constructing hundreds of paths to hit-test screen locations seems like overkill. If you have a room with seats, likely the room has a small number of sections (maybe only one) in which seats are laid out in a grid. Therefore you only need to keep the bounds of each section. It should be straightforward to translate a touch location into a grid position mathematically. Or, in the worst case, keep each seat as a separate rectangle and test the touch location against the rectangles. If you need non-rectangular hit testing, then it's still likely better to test against rectangular bounds rects first, and test against a more complex shape only when the first test succeeds. _______________________________________________ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.
