Lifting the Lid on the iOS 7 UIPicker
Sean Woodhouse (via Mike Rundle):
As you can see from Marc’s diagram, you can no longer drag above and below the AM/PM column to move it. This is a huge pain because now you have to place your finger over the content in order to make your selection. In iOS 6 I’d often push or pull underneath the selected AM/PM value to change it. You’re also not able to tap the AM/PM or minute items to select them, which is completely inconsistent because you can tap the day and hour items!
Hopefully these were unintentional changes that will be fixed, because I’m finding the new picker difficult to use.
