Customising the font/background colour of index/section bar in UITableView

Question

I\'ve read in another thread on SO that you can adjust the font or background colour of the index bar (that is the A-Z # scrollbar) in a UITableView adding a CALayer. My app

Answer 1

For Swift 3.1:

 self.tblViewForContacts.sectionIndexTrackingBackgroundColor = self.view.backgroundColor
 self.tblViewForContacts.sectionIndexBackgroundColor = self.view.backgroundColor

Answer 2

Here is code for swift 2+

self.tableView.sectionIndexTrackingBackgroundColor = CustomColor
// background color while the index view is being touched
self.tableView.sectionIndexBackgroundColor = CustomColor
// title/text color of index items 
self.tableView.sectionIndexColor = CustomColor

Answer 3

As of iOS 6.0 there are two methods that allow you to change the color of the section indexes and the background shown when you drag along the section indexes.

if ([tableView respondsToSelector:@selector(setSectionIndexColor:)]) {
    tableView.sectionIndexColor = ... // some color
    tableView.sectionIndexTrackingBackgroundColor = ... // some other color
}

Of course this will only execute if the device has 6.0 or later. Under iOS 5.x, nothing will change.
