/** @def CCARRAY_FOREACH
A convenience macro to iterate over a Array using. It is faster than the "fast enumeration" interface.
@since v0.99.4
*/

/*
In cocos2d-iphone 1.0.0, This macro have been update to like this:

#define CCARRAY_FOREACH(__array__, __object__)                                                \
if (__array__ && __array__->data->num > 0)                                                    \
for(id *__arr__ = __array__->data->arr, *end = __array__->data->arr + __array__->data->num-1;    \
__arr__ <= end && ((__object__ = *__arr__) != nil || true);                                        \
__arr__++)

I found that it's not work in C++. So it keep what it's look like in version 1.0.0-rc3. ---By Bin
