No need to do some complicated things, you only need to change the tintColor property of the UIAlertController main view like this :
不需要做一些复杂的事情，你只需要像这样更改 UIAlertController 主视图的 tintColor 属性：
let alert = UIAlertController(title: "Title", message: "Some message", preferredStyle: .Alert)
alert.view.tintColor = UIColor.redColor()
let action = UIAlertAction(title: "Ok", style: .Default, handler: nil)
alert.addAction(action)
This way your buttons tint will be red (or whatever color you want)
这样你的按钮就会变成红色（或者你想要的任何颜色）
