Detecting tap inside a bezier path

Question

I have a UIView which is added as a subview to my view controller. I have drawn a bezier path on that view. My drawRect implementation is below

- (void)drawR         


        

Answer 1

There is a function CGPathContainsPoint() it may be useful in your case.

Also be careful if you get gesture point from superview, the coordinate may not be correct with your test. You have a method to convertPoint from or to a particular view's coordinate system:

- (CGPoint)convertPoint:(CGPoint)point toView:(UIView *)view
- (CGPoint)convertPoint:(CGPoint)point fromView:(UIView *)view
