How to change the background color of the UIAlertController?

Question

Due to strange behavior of UIActionSheet in iOS 8, I have implemented UIAlertController with UIAction as buttons in it. I would like to change the entire background of the UIAlertController. But I can't find any ways to do it.

Tried even with,

actionController.view.backgroundColor = [UIColor blackColor]; 

But didn't help me out. Any inputs on this regard will be appreciable.

Thanks in advance.

You have to step some views deeper:

let subview = actionController.view.subviews.first! as UIView let alertContentView = subview.subviews.first! as UIView alertContentView.backgroundColor = UIColor.blackColor() 

And maybe you want to keep original corner radius:

 alertContentView.layer.cornerRadius = 5; 

Sorry for the "Swifting" but i'm not familiar with Objective-C. I hope that's similar.

Of course it's also important to change the title color of the actions. Unfortunately I don't know, how to set the color of actions separately. But this is, how you change all button text colors:

actionController.view.tintColor = UIColor.whiteColor(); 

EDIT:

The corner radius of the UIAlertController has changed since this answer's been posted! Replace this:

 alertContentView.layer.cornerRadius = 5; 

to this:

 actionContentView.layer.cornerRadius = 15
