Collision detection on sub views contained in 2 separate parent UIViews?
I originally setup some conditions using CGRectIntersectsRect for some collision detection which worked fine. In the greater scale of things I only need part of the view to be detected.
So originally within the ViewContro开发者_StackOverflow中文版ller it was comparing 2 UIviews.
Now what I need to do is collision detection of subViews within 2 different UIViews that are contained in a view in which the view controller does the logic.
My script is no longer working as I suspect CGRectIntersectsRect only compares frames within the same view? I'll keep digging to confirm this.
Any ways around this? Is it possible for example to get the x and y pos of the sub view in relation to the main view that's performing the logic?
You'll need to use UIView's convertRect:toView:
or convertRect:fromView:
(or the point equivalents) to get them in the same coordinate space.
