NSArray *array = [viewControllers allValues];
for (int i = 0; i<array.count; i++) {        
    MenuListingVC *vc = array[i];
    [vc tableDataReload];
}

I'm not entirely clear what your question is asking, but you might be looking for:

for (id currentValue in [dictobj allValues])
{
    //stuff with currentValue
}
