When I bring up console after my iPhone app crashes, it often says “unrecognized selector sent to instance 0x blah blah blah.” How can I find out what variable this is? Is there a way in the debugger? Is it even possible? Thanks.

In gdb you could type
to print the
-descriptionof the object at that address. But this info is seldom useful. You should instead check the backtrace of the exception first, which can locate the line of code that causes the problem.
