scrollsToTop on UIScrollView did not work

Question

I've set up scrollTopTop property in my UIScrollView to YES however, when I tap on my status bar it didn't work. Why is this?

I have a UIViewController called A and inside A I have a UIViewController B, which has the UIScrollView. Is this the reason why it's not working?

Yes, you can have some instructions from the following [link](http://stackoverflow.com/questions/1361614/iphone-os-tap-status-bar-to-scroll-to-top-doesnt-work-after-remove-add-back) — rshahriar, Jul 16 '12 at 07:22
The following code can help you do that: `[[A view] bringToFront:[B view]]` — rshahriar, Jul 16 '12 at 07:28

Make sure of somethings:

Scrollview is at the front.
Make sure it's re-enabled after you add/remove your status bar.
There is only one scrollview because many of them will prevent it from scrolling to top.
Make sure that B view at front as well of A view.

Sorry but the question has to have more details so that we can help :)

what other details do you need? – xonegirlz Jul 16 '12 at 14:52
I never hide/unhode the scroll view and there's only one scroll view – xonegirlz Jul 16 '12 at 14:53
I've done self.view bringSubviewToFront:self.scrollView on B and did self.view bringSubViewToFront:B.view from A – xonegirlz Jul 16 '12 at 16:34

UIViewController B should be added in UIViewController A. like this, when you added b.view in a, you should add this code : [self addChildViewController:b]

I had an app where scrollsToTop was working. Later on, I added a UICollectionView and scrollsToTop stopped working. After tracking down the offending revision I had to set UICollectionView.scrollsToTop = NO. I overlooked the fact that UICollectionView also inherits from UIScrollView.
