iOS Overlapping

[Stratoukos]

Just a simple question.

I was wondering if ther is a built-in way to check if two shapes (drawn with quartz) overlap. The shapes won't necessarily be simple ones like circles.

Thanks.

No: there is no built-in collision detection/overlap detection...

You'll have to implement your own collision detection for this as Quartz only sees the context as a drawing canvas that it can draw to when told. It shouldn't be too hard seeing as you are obviously creating the paths for the shapes in the first place
