如何在swift ui中显示STPPaymentOptionsViewController

import Stripe

class MyViewController: UIViewController, STPPaymentContextDelegate {
    var paymentContext: STPPaymentContext?
    
    override func viewDidLoad() {
        super.viewDidLoad()
        
        // 创建STPPaymentContext对象
        paymentContext = STPPaymentContext(apiAdapter: MyAPIClient.shared, configuration: MyStripeConfig.shared, theme: .defaultTheme)
        
        // 设置代理
        paymentContext?.delegate = self
    }
    
    @IBAction func showPaymentOptions(_ sender: UIButton) {
        // 显示STPPaymentOptionsViewController
        paymentContext?.presentPaymentOptionsViewController()
    }
    
    // 实现STPPaymentContextDelegate方法
    // ...
}

extension MyViewController: STPPaymentContextDelegate {
    func paymentContextDidChange(_ paymentContext: STPPaymentContext) {
        // 更新UI，例如显示选中的支付选项
    }
    
    func paymentContext(_ paymentContext: STPPaymentContext, didFailToLoadWithError error: Error) {
        // 处理加载支付选项时的错误
    }
    
    func paymentContext(_ paymentContext: STPPaymentContext, didFinishWith status: STPPaymentStatus, error: Error?) {
        // 处理支付完成后的结果
    }
}
