我想将图像放在 AppStore 上的 ActionSheet 的右侧.我知道如何添加图像并更改 titleText 样式，但我无法弄清楚如何更改这两个的位置.

I want to put the image to the right in an ActionSheet as seen on the AppStore. I know how to add an image and change the titleText style but I am unable to figure out how to change the positions of these two.

第三方库不受欢迎.

如何自定义 UIAlertControllerUITableView 或者在 Pages 应用程序中是否有像这个 UI 一样可用的默认控件?

import Foundation
import UIKit

class CustomActionSheet: UIAlertController{

    private var controller : UITableViewController


    override init(nibName nibNameOrNil: String?, bundle nibBundleOrNil: Bundle?) {

        controller = UITableViewController(style: .plain)
        super.init(nibName: nibNameOrNil, bundle: nibBundleOrNil)
        controller.tableView.register(UITableViewCell.self, forCellReuseIdentifier: "cell")
        controller.tableView.dataSource = self
        controller.tableView.addObserver(self, forKeyPath: "contentSize", options: [.initial, .new], context: nil)
        self.setValue(controller, forKey: "contentViewController")
    }

    required init?(coder aDecoder: NSCoder) {
        fatalError("init(coder:) has not been implemented")
    }
    deinit {
        controller.tableView.removeObserver(self, forKeyPath: "contentSize")
    }

    override func observeValue(forKeyPath keyPath: String?, of object: Any?, change: [NSKeyValueChangeKey : Any]?, context: UnsafeMutableRawPointer?) {
        guard keyPath == "contentSize" else {
            return
        }

        controller.preferredContentSize = controller.tableView.contentSize
    }

}

extension CustomActionSheet: UITableViewDataSource {
    func tableView(_ tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
        return 4
    }

    func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
        let cell = tableView.dequeueReusableCell(withIdentifier: "cell")!

        switch(indexPath.row) {
        case 0:
            cell.textLabel?.text = "Share Link via iCloud"
            cell.accessoryView = UIImageView(image:UIImage(named:"image1.png")!)
            break
        case 1:
            cell.textLabel?.text = "Send a Copy"
           cell.accessoryView = UIImageView(image:UIImage(named:"image2.png")!)
            break
        case 2:
            cell.textLabel?.text = "Open in Another App"
            cell.accessoryView = UIImageView(image:UIImage(named:"image3.png")!)
            break
        case 3:
            cell.textLabel?.text = "Move to..."
            cell.accessoryView = UIImageView(image:UIImage(named:"image4.png")!)
            break
        default:
            fatalError()
        }

        return cell
    }
}

你可以从你的视图控制器中使用这个自定义类

You can use this custom class from your view controller

let controller = CustomActionSheet(title: nil, message: nil, preferredStyle: .actionSheet)
        controller.addAction(UIAlertAction(title: "Cancel", style: .cancel, handler: nil))
        self.present(controller, animated: true, completion: nil)
