我想更改警报控制器的背景以匹配游戏背景,文本字体以匹配游戏文本字体在这里是我正在使用的代码,但无法正常工作
let alertController = UIAlertController(title: "Time Up!", message: "Your time is up! You got a score of \(point) points and your total coins now is \(totalPoints). You Can Do Better", preferredStyle: .alert)
let restartAction = UIAlertAction(title: "Play Again!", style: .default, handler: nil)
alertController.addAction(restartAction)
alertController.view.tintColor = UIColor(red: 226, green: 158, blue: 152, alpha: 1.0 )
alertController.view.backgroundColor = UIColor(red: 226, green: 158, blue: 152, alpha: 1.0)
alertController.view.layer.cornerRadius = 15
self.present(alertController, animated: true, completion: nil)

警报控制器是默认的iOS控制器。您可以创建自定义视图。添加标签,按钮并在其上应用颜色主题。
或者有第三方库,您可以使用它。

在更改UIAlertController background color
时,您需要这样做:
alertController.view
.subviews.first?
.subviews.first?
.subviews.first?
.backgroundColor = UIColor(red: 226/255.0, green: 158/255.0, blue: 152/255.0, alpha: 1.0)
在设置RGB UIColor时,还必须包含 / 255 才能起作用。示例:
UIColor(red: 226/255.0, green: 158/255.0, blue: 152/255.0, alpha: 1.0)
