ARC perform selector?

- (void)ks_tryToMakeObjectsPerformSelector:(SEL)selector withObject:(id)object;
{
    for (id <NSObject> anObject in self)
    {
        if ([anObject respondsToSelector:selector])
        {
            [anObject performSelector:selector withObject:object];
        }
    }
}

- (void)ks_tryToMakeObjectsPerformSelector:(SEL)selector withObject:(id)object;
{
    for (id <NSObject> anObject in self)
    {
        if ([anObject respondsToSelector:selector])
        {
            IMP imp = [anObject methodForSelector:selector];
            void (*func)(id, SEL, id) = (void *)imp;
            func(anObject, selector, object);
        }
    }
}
