Here's the function I use in CamelBones to iterate through all registered
classes. It hasn't been updated to Leopard's new ObjC 2.0 runtime yet, but
neither have most Mac users. :-)
// Create Perl wrappers for all registered ObjC classes
void REAL_CBWrapRegisteredClasses(void) {
int numClasses;
Class *classes;
int i;
classes = NULL;
numClasses = objc_getClassList(NULL, 0);
if (numClasses > 0) {
classes = malloc(sizeof(Class) * numClasses);
objc_getClassList(classes, numClasses);
for(i=0; i < numClasses; i++) {
REAL_CBWrapObjectiveCClass(classes[i]);
}
free(classes);
}
}
