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();
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
