iPhone Core Animation - Drawing a Circle

http://stackoverflow.com/questions/7991086/iphone-core-animation-drawing-a-circle

Thanks iphone core animation share improve this question What you really should do is to animate the stroke of a CAShapeLayer where the path is a circle. This will be accelerated using Core Animation and is less messy then to draw part of a circle.. width of the stroke you should use lineWidth instead of borderWitdh etc. Set up the shape of the circle int radius 100 CAShapeLayer circle CAShapeLayer layer Make a circular shape circle.path UIBezierPath bezierPathWithRoundedRect CGRectMake 0 0 2.0 radius.. you should use lineWidth instead of borderWitdh etc. Set up the shape of the circle int radius 100 CAShapeLayer circle CAShapeLayer layer Make a circular shape circle.path UIBezierPath bezierPathWithRoundedRect CGRectMake 0 0 2.0 radius 2.0 radius cornerRadius..
