Does the IKImageView imageCorrection property work?

IKImageView has an 'imageCorrection' property, which is a CIFilter.

Presumably the idea is that you set up a CIFilter instance, then call

myIKImageView.imageCorrection = myFilter;

then that filter will automatically be applied to whatever image is  
displayed in the IKImageView. I would think this is how the HUD  
applies its corrections.

Has anyone been able to use this successfully?

When I tried it, after the assignment the property remained nil.

I suspect there is something that is not documented, some state that  
has to be in place before this works. I tried giving the IKImageView a  
CA layer in IB, but that didn't help.
