Yes, I have a blog post about it here. The short answer is to borrow the JTAInnerShadowLayer from here, subclass UILabel, and change its layerclass by overriding + (Class)layerClass so that it returns JTAInnerShadowLayer class like this:

+ (Class)layerClass
{
  return [JTAInnerShadowLayer class];
}

Then in the init method for the layer set up the JTAInnerShadowLayer something like this:

[self setBackgroundColor:[UIColor clearColor]];
JTAInnerShadowLayer *innerShadow = (JTAInnerShadowLayer *)[self layer];
[innerShadow setClipForAnyAlpha:YES];
[innerShadow setOutsideShadowSize:CGSizeMake(0.0, 1.0) radius:1.0];
[innerShadow setInsideShadowSize:CGSizeMake (0.0, 4.0) radius:6.0];
/* Uncomment this to make the label also draw the text (won't work well
   with black text!*/
//[innerShadow drawOriginalImage];

(or just borrow the JTAIndentLabel class).
