Using transition CIFilters for CATransition

Question

I'm trying to use CATransition's filter property with the new iOS 6 transition animations (CIBarsSwipeTransition, CICopyMachineTransition, etc.). The CIFilter documentation says that these are available on iOS 6, and nothing on the CATransition documentation says that the filter property cannot be used.

But, I can't seem to get them to work. I don't know if Apple just failed to mention the inavailability of the functionality or I'm just missing something to make it work. Here's how I set it up:

CIFilter *transitionFilter = [CIFilter filterWithName:@"CIBarsSwipeTransition"];
[transitionFilter setDefaults];

CATransition *transition = [CATransition new];
transition.duration = 0.4f;
transition.filter = transitionFilter;

[self.view.layer addAnimation:transition forKey:kCATransition];

Any pointers are appreciated.

I know that question is quite old but I got mine working by following that link

Check the 11 steps in the section "Using Transition Effects" it works on iOS as well
