Once you have changed the modal view controller style to a form sheet, when you then add a new item, if you then rotate the iOS simulator, this newly added item magically appears in the ItemsViewController table underneath (before you’ve clicked the Done button). If you then click Cancel, it promptly disappears.
If there are any existing items in the table, when you add another item, then rotate again, the item once again appears underneath the modal view, with the item cell above it still have the rounded bottom edge as if it was the last cell.
Is this an iOS simulator bug? I can’t test on a device.
