如何在iOS 11的状态栏上正确添加模糊效果而不出现警告？

import UIKit

class YourViewController: UIViewController {
    override func viewDidLoad() {
        super.viewDidLoad()
        
        let blurEffect = UIBlurEffect(style: .light)
        let blurView = UIVisualEffectView(effect: blurEffect)
        
        if #available(iOS 11.0, *) {
            let statusBar = UIApplication.shared.value(forKey: "statusBar") as? UIView
            statusBar?.addSubview(blurView)
        } else {
            // Fallback on earlier versions
            view.addSubview(blurView)
        }
        
        // 设置模糊视图的约束或位置
        blurView.translatesAutoresizingMaskIntoConstraints = false
        blurView.leadingAnchor.constraint(equalTo: view.leadingAnchor).isActive = true
        blurView.trailingAnchor.constraint(equalTo: view.trailingAnchor).isActive = true
        blurView.topAnchor.constraint(equalTo: view.topAnchor).isActive = true
        blurView.bottomAnchor.constraint(equalTo: view.safeAreaLayoutGuide.topAnchor).isActive = true
    }
}
