This statement is true; however those integers happen to be the memory addresses of unique instances of the strings*. This makes it very efficient for the runtime to convert a selector to an NSString, and vice versa, and also helps with debugging (in gdb you can just type "print (char*)sel" to inspect a selector.)

Don't forget NSStringFromSelector, which I find is usually more convenient and doesn't rely on implementation details. Invoke it in GDB by casting its return value to id:

po (id)NSStringFromSelector(_cmd)

(Although I have noticed that gdb is much better about inferring when it can expect an object return value from a function/method call).
