Reminders.app UIScrollView scrolling explanation.

Question

I am currently programming an application for the iPhone and I am having some issues with my horizontal (horizontal as in you scroll horizontally, not vertically) UIScrollView.

The UIScrollView's height is 260 and the width is 320. It has 2 pages and each page has a UITableView in it. The UITableView's frame is the same as the UIScrollView's frame.

The problem is that 80% of the time, the current UITableView detects the drag/swipe as a vertical scroll (but it's actually horizontal) and begins to scroll the table view vertically.

My question is the following:

Can somebody explain to me how the app Reminders does for the scrollview scrolling. If you look carefully, you can see that the scrollview handles the horizontal scrolling very well and that a horizontal scroll is handled by the scrollview (and not by the tableview like mine does). If anyone needs more explanation please leave a comment.

Answer 1

If I try to scroll to the left/right in the table view of Reminders, it doesn't respond to it. If I scroll in the table header view where the add button is, it scrolls without any problems. My guess is that they made the table view header a UIScrollView. Apple highly discourages the use of a table view in a scroll view (or any view that inherits from UIScrollView into a different view that inherits from UIScrollView, for that matter), so they probably wouldn't take their own advice and ignore it.
