I am using new UIAlertController for showing alerts. I have this code:
// nil titles break alert interface on iOS 8.0, so we\'ll be using empty strings

You can use an external library like PMAlertController without using workaround, where you can substitute Apple's uncustomizable UIAlertController with a super customizable alert.
Compatible with Xcode 8, Swift 3 and Objective-C
