How to Get the reverse path of a UIBezierPath

Question

self.myPath=[UIBezierPath bezierPathWithArcCenter:center 
                                           radius:200 
                                       startAngle:0 
            


        

Answer 1

I have two solution for you.

1. Draw this path on a CALayer. And use that CALayer as a mask layer for you actual CALayer.

2. Draw a rectangle with the sizes of you frame before adding arc.

   UIBezierPath *path = [UIBezierPath bezierPathWithRect:view.frame];
   [path addArcWithCenter:center 
                   radius:200 
               startAngle:0 
                 endAngle:2*M_PI 
                clockwise:YES];
   

I would use second solution. :)
