Question: On iOS 6, my UITableView's section index would distribute all of its items evenly across the height of the table view. In iOS 7 all of the items are clumped together in the middle, making the items difficult to tap. Is there any way to space them out?

Answer: 
One of possible solutions here - is to add empty string just after each adding of real title to your section index title array and returning index divided by 2 at your `tableView: sectionForSectionIndexTitle: atIndex:` method.

This trick slightly increase distance between successive titles, but doesn't completely solve this problem.
I tried this mod and it works, but you also have to set call the routine in the viewDidAppear method so every time the view appears you need to call this routine and then reload your table.
