ios - 复制 iOS 11 控制中心屏幕

Question

我正在尝试重新创建 iOS 11 控制中心视图。我还没有尝试使其功能化，但我正在尝试获得相同的样式，但我无法确定它在 iOS 11 中的外观。我该怎么做？这是迄今为止我想要的，当然没有模糊视图上的按钮。有小费吗？谢谢。

import UIKit
import PlaygroundSupport

let view = UIImageView(image: #imageLiteral(resourceName: "IMG_5413.PNG"))
view.backgroundColor = .white
view.frame = CGRect(x: 0, y: 0, width: 350, height: 650)

let light = UIBlurEffect(style: .light)
let lightView = UIVisualEffectView(effect: light)
lightView.layer.masksToBounds = true
lightView.frame = view.frame
lightView.autoresizingMask = [.flexibleWidth, .flexibleHeight]
view.addSubview(lightView)

let dark = UIBlurEffect(style: .dark)

let darkView = UIVisualEffectView(effect: dark)
darkView.layer.cornerRadius = 50
darkView.layer.masksToBounds = true
darkView.frame = CGRect(x: 50, y: 50, width: 250, height: 250)
darkView.autoresizingMask = [.flexibleWidth, .flexibleHeight]
view.addSubview(darkView)

PlaygroundPage.current.liveView = view
