-[CFString respondsToSelector:]: message sent to deallocated instance 0x4b9e720
I don’t where to start, tried static analyzer and stepped through each line of code but still no help.
It means you are trying to use an object which has been deallocated – i.e. sent
releaseorremoveFromSuperview:Check this page to see how to enable a debug feature called NSZombie – it keeps objects alive even when released, and lets you know which one you are accessing. The downside is that the program uses much more memory (since nothing is truly released) but you only use it until you have found the problem then turn it off.
