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: 
Here is something I played with and works. It follows Anton M's advice, uses Swift 2 and ios 9.

Let's say you have the following section indexes:

```
let indexes: [String] = ["A", "B", "C", "D", "E"]

```

So that everyone is on the same page, A is at index 0. B is at index 1 and so on.

Lets assume you want two spaces between indexes. Then define your section indexes as:

```
let indexes: [String] = ["A", "", "", "B", "", "", "C", "", "", "D", "", "", "E"]

```

So now, A is still at index 0 but B is now at index 3, C is at 6, D is at 9 and E is at 12.

All you need is to figure out the offset in the sectionForSectionIndexTitle. What you are after is the index of a real title as this is what you have in your table. Therefore:

```
override func tableView(tableView: UITableView, sectionForSectionIndexTitle title: String, atIndex index: Int) -> Int {        
        return index / 3
}

```

So, for every extra space you need between the indexes you need to add 1 to the enumerator of the above expression. You can easily test this in Playground.
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.
