iPhone 弹出菜单像 iPad 弹出菜单一样吗

swift
import UIKit
class ViewController: UIViewController {
    @IBOutlet weak var button: UIButton!
    override func viewDidLoad() {
        super.viewDidLoad()
    }
    @IBAction func showMenu(_ sender: UIButton) {
        let alertController = UIAlertController(title: "菜单", message: "请选择一个选项", preferredStyle: .actionSheet)
        alertController.addAction(UIAlertAction(title: "选项 1", style: .default, handler: { (action) in
            // 执行选项 1 的操作
        }))
        alertController.addAction(UIAlertAction(title: "选项 2", style: .default, handler: { (action) in
            // 执行选项 2 的操作
        }))
        alertController.addAction(UIAlertAction(title: "取消", style: .cancel, handler: nil))
        if let popoverController = alertController.popoverPresentationController {
            popoverController.sourceView = button
            popoverController.sourceRect = button.bounds
        }
        present(alertController, animated: true, completion: nil)
    }
}
