My iPhone app started logging this error:
lo->hi recycling invariant violated!
 followed by:
Program received signal: “EXC_BAD_ACCESS”
 whenever I launched it on my iPod (3.1.3) and sometimes when I launch it in the simulator.

What does this error mean, and how can I fix it?

I am using cover-flow in my app. I think this might be the problem.

Thanks in advance.

Yes cover flow is the problem. Note that UICoverFlowLayer is private API. If you're targeting for AppStore, consider other alternatives here.

The error "lo->hi recycling invariant violated!" is raised by -[UICoverFlowLayer _updateTick], which should be caused by reusing the wrong sublayer for display. The detail I don't know because there's no detail code, nor I'm familiar with the Cover Flow API.

  • It turns out, after some debugging, that the only thing wrong that the cover-flow was being initialized with zero covers. – cduck Mar 17 '10 at 06:09
