有没有办法把preferredStatusBarStyle和RxCocoa捆绑在一起？

import UIKit
import RxSwift
import RxCocoa

extension Reactive where Base: UIViewController {
    var preferredStatusBarStyle: Binder<UIStatusBarStyle> {
        return Binder(self.base) { viewController, statusBarStyle in
            viewController.preferredStatusBarStyle = statusBarStyle
            viewController.setNeedsStatusBarAppearanceUpdate()
        }
    }
}

import UIKit
import RxSwift
import RxCocoa

class MyViewController: UIViewController {
    private let disposeBag = DisposeBag()

    override func viewDidLoad() {
        super.viewDidLoad()

        // 创建一个Observable来表示preferredStatusBarStyle的变化
        let statusBarStyleObservable = Observable<UIStatusBarStyle>.just(.lightContent)

        // 使用RxCocoa的扩展将preferredStatusBarStyle和状态栏样式绑定在一起
        statusBarStyleObservable
            .bind(to: rx.preferredStatusBarStyle)
            .disposed(by: disposeBag)
    }
}
