如何确定哪个NSArray导致了XCode中的异常

Question

I have a small project with about 5 or 6 arrays. Im getting a problem saying that my NSArray collection was mutated while being enumerated. But it doesn't tell me which Array its referring to.

How can I visualize which one it is in order to fix it?

You can always use your friend NSLog, as you are looping through your arrays:

NSLog(@"your_array_name contains: %@", your_array_name");

It never hurts to print out the contents of each of your arrays to make sure you know what's being stored in them.
