Title Body

When I set the transform property of my CALayer with a CATransform3DRotate, the layer is properly rotated. However, the edges of the layer are jagged and not anti-aliased. I've read a couple posts on the subject: iPhone: CALayer + rotate in 3D + antialias? iPhone - Jagged Edges when applying perspective to CALayer I've tried to incorporate their advice by setting the following properties on my diagonal layer CALayer* layer = myView.layer; layer.shadowOpacity = 0.01; layer.edgeAntialiasingMask = kCALayerTopEdge | kCALayerBottomEdge | kCALayerRightEdge | kCALayerLeftEdge; layer.borderWidth = 1.0; layer.borderColor = [UIColor clearColor].CGColor; layer.backgroundColor = [UIColor greenColor].CGColor; I've also overridden the drawLayer:inContext: method of my diagonal layer to ensure anti-aliasing: -(void)drawLayer:(CALayer*)layer inContext:(CGContextRef)context { CGContextSetAllowsAntialiasing(context, true); CGContextSetShouldAntialias(context, true); CGContextSetFillColorWithColor(context, [UIColor greenColor].CGColor); CGContextFillRect(context, self.bounds); } What am I missing?
