针对状态栏高度做一些操作

import UIKitclass ViewController: UIViewController {private var statusBarFrameObservation: NSKeyValueObservation?override func viewDidLoad() {super.viewDidLoad()if let statusBarManager = UIApplication.shared.windows.first?.windowScene?.statusBarManager {statusBarFrameObservation = statusBarManager.observe(\.statusBarFrame, options: [.new, .old]) { _, change in// 处理状态栏变化print("Status bar frame changed from \(change.oldValue) to \(change.newValue)")}}}
}
