more detailed information about the exception in xcode

Question

So I am trying to troubleshoot why adding an item to my dictionary causes an exception.

It turns out that I used a NSDictionary instead of NSMutableDictionary.

However the exception I saw... setobject format exception was no help at all.

Where do you look in xCode to get detailed exception information? Or is this all that is given?

Answer 1

It's unfortunate that the emitted stacktrace contains the memory address of the method calls on the stack rather than their names.

I recommend using the debugger and setting a breakpoint at objc_exception_throw. The debugger can tell exactly where the exception was made and what the arguments were.

markjnet provides a nice writeup on exception debugging here.
