swift - 将图像添加到 ActionSheet 并将其放在右侧

Question

我想将图像放在 ActionSheet 的右侧，就像在 AppStore 上看到的那样。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者的位置。

第三方库不受欢迎。

谢谢!

How to customize UIAlertController with UITableView or is there any default control available like this UI in Pages app?

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
    }
}

您可以在您的 View Controller 中使用这个自定义类

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)
