int numClasses;

Class *classes =
NULL;

classes = NULL;

numClasses = objc_getClassList(NULL,
0);

NSLog(@"Number of classes: %d",
numClasses);

if (numClasses >
0 )

{

classes = (__unsafe_unretained Class *)malloc(sizeof(Class)
* numClasses);

numClasses = objc_getClassList(classes, numClasses);

for (int
i = 0; i < numClasses; i++) {

NSLog(@"Class name: %s",
class_getName(classes[i]));

}

free(classes);
