如何在基于页面的WatchOS界面中显示警报？

import WatchKit
import UIKit

let alertController = UIAlertController(title: "警报标题", message: "警报消息", preferredStyle: .alert)

let okAction = UIAlertAction(title: "确定", style: .default) { (action) in
    // 点击确定按钮后的操作
}
alertController.addAction(okAction)

present(alertController, animated: true, completion: nil)

import WatchKit
import UIKit

class InterfaceController: WKInterfaceController {

    @IBAction func showAlertButtonTapped() {
        let alertController = UIAlertController(title: "警报标题", message: "警报消息", preferredStyle: .alert)
        
        let okAction = UIAlertAction(title: "确定", style: .default) { (action) in
            // 点击确定按钮后的操作
        }
        alertController.addAction(okAction)
        
        present(alertController, animated: true, completion: nil)
    }
}
