Can renderInContext: maintain corner radius and shadows?

I have a custom UILabel with round corners and a drop shadow. I'm using the properties on CALayer to achieve this. Next, I'm trying to save this as a UIImage using renderInContext:. The round corners are maintained, but a black background appears and a loose the drop shadow. Any thoughts on rendering the UILabel as an image but maintaining the shadow and rounded corners? Here's the code I'm using to render the label: ``` UIGraphicsBeginImageContextWithOptions(label.bounds.size, YES, 0); [label.layer renderInContext:UIGraphicsGetCurrentContext()]; UIImage *image = UIGraphicsGetImageFromCurrentImageContext(); UIGraphicsEndImageContext(); ```
