Nested UIScrollView prevents bounce ignition and allows parent paging when at the end of the list

Question

I want to recreate the same behavior as the weather app in iOS7. Here is a screenshot:

The main screen is a UIScrollView that contains a nested UIScrollView that scrolls left and right.

I have implemented this in many ways, but I do not understand that this is true. If I just do something like this:

| UIScrollView
| ---> UICollectionView

When I scroll left and right quickly, this will cause the parent screen to crash, which will cause you to see the next page. I do not want it. I tried using all the delegates to try to disconnect the parent while the child scrolls, but this never behaved and was awkward.
