I have a subclassed `UIView` loaded from a nib, and I cannot get a shadow to draw around it. I'm trying to get a shadow to appear around the entire view for quite some time now. I elected to place it in it's own sublayer to simplify animating it later. Here's the code:

```
-(void)awakeFromNib 
{
    self.clipsToBounds = NO;

    // set up the shadow layer
    CALayer *shadow = [CALayer layer];
    shadow.frame = CGRectMake(self.frame.origin.x, self.frame.origin.y, self.bounds.size.width, self.bounds.size.height);
    shadow.shadowColor = [UIColor blueColor].CGColor;
    shadow.shadowRadius = 15.0;
    shadow.opacity = 1.0;
    [self.layer addSublayer:shadow];
    // I set this property so I have access to it later to more easily animate it.
    self.shadowLayer = shadow;
}

```

When I `NSLog` the `shadowLayer` property, the coordinates and frame are correct. It's matches the view it's backing.

I also set a border color and corner radius on `self.layer` and it appears correctly. If I put the shadow on `self.layer` it appears but it encompasses all the subviews of my parent `UIView`.

Any help is greatly appreciated.
