UItableView get UIScrollView for customization

UItableView get UIScrollView for customization

I have category for UIScrollView for customization
I need get UIScrollView.
I try
UIScrollView *scroll = nil;
for (UIView* subview in self.tableView.subviews) {
NSLog(@"%i", self.tableView.subviews.count);
if ([subview isKindOfClass:[UIScrollView class]]) {
scroll = (UIScrollView *)subview;
//some code
}
}
But it doesn't work. How I can get ScrollView? Thanks
