Draw smooth circle in iOS sprite kit

ios drawing sprite-kit geometry antialiasing

The antialiasing is activated by default, but It only applies to the lines, not the fill.

Set the lineWidth to a number greater than 0 and try again.

ios drawing sprite-kit geometry antialiasing

Set the antialised property to YES.

shapeNode.antialiased = YES;

The rough edges are not visible when you use fill color.

//shapeNode.fillColor = [SKColor redColor];shapeNode.strokeColor =[SKColor redColor];shapeNode.antialiased = YES;shapeNode.lineWidth = 1;

Now switch between YES and NO for antialisaed property.You will notice the difference.
