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 the workaround by Jatin, but the result was only the change in colour and font of the section index. It remains vertically compressed and centered.

I think this is the new behaviour of iOS7 (although I think this is not the best visual appearance). This behaviour is visible also in this official document from Apple: [iOS Human Interface Guidelines - Table View](https://developer.apple.com/library/ios/documentation/UserExperience/Conceptual/MobileHIG/ContentViews.html#//apple_ref/doc/uid/TP40006556-CH13-SW3)
