You can't. You can, however, make it so that the method is only 
present when Leopard is the deployment target by doing something like 
this:

#if MAC_OS_X_VERSION_MIN_REQUIRED <= MAC_OS_X_VERSION_10_4
...
#endif

That way, the method will be included as long as you're targeting 
Tiger, but once you change that to Leopard, then your implementation 
will no longer be used.
