问题
Is it possible to change the 'gravity' (stop speed) when scrolling through a UIScrollView with paging enabled? I've implemented a horizontal UIScrollView that acts like the UIPickerView. I want to be able to scroll through many items based on the flick speed. Thanks!

Unfortunately there's no simple property you can change to achieve this, but you can use the scrollview delegate methods to roll your own (it is somewhat complex, but achievable - I've modified table views to 'snap' to rows when the scrolling comes to an end).
Effectively, you'll have to code your own paging implementation.
