如何使用 Swift 将 JSON 数组数据加载到 UIActionSheet 按钮标题中

I have JSON内的数据array。我需要加载这个数组数据UIActionSheet button title。在这里，我尝试使用单个创建一个通用的 UIActionSheetbutton。基于数组字符串，我需要加载数据作为按钮标题。我确信，我从来没有从 JSON 中获得超过 4 个数组索引，所以我想将其加载到操作表中并根据单击获取 id 值。我不知道如何加载它，作为按钮标题。

我的 JSON 编码

   // MARK: - Welcome
struct Welcome: Codable {
    let status: Bool
    let data: DataClass
}

// MARK: - DataClass
struct DataClass: Codable {
    let id, rollnum, osname, dataDescription: String
    let team: [Team]
    let record, score: [String]
    let titles: [Title]

    enum CodingKeys: String, CodingKey {
        case id, rollnum, osname
        case dataDescription = "description"
        case team, record, score, titles
    }
}

// MARK: - Team
struct Team: Codable {
    let name, group: String
}

// MARK: - Title
struct Title: Codable {
    let status, id, icon: String
}

JSON解码器

var titleData = [Title]()

override func viewDidLoad() {
    super.viewDidLoad()
    self.loadJSON()
}

// MARK: JSON Data Load

func loadJSON(){
    let urlPath = ""
    let url = NSURL(string: urlPath)
    let session = URLSession.shared
    let task = session.dataTask(with: url! as URL) { data, response, error in
        guard data != nil && error == nil else {
            print(error!.localizedDescription)
            return
        }
        do {
            let decoder = try JSONDecoder().decode(Welcome.self,  from: data!)
            self.titleData = decoder.data.titles
        } catch { print(error) }
    }
    task.resume()
}

Objective C 示例需要更改 Swift 5

NSArray *array = @[@"1st Button",@"2nd Button",@"3rd Button",@"4th Button"];

    UIActionSheet *actionSheet = [[UIActionSheet alloc] initWithTitle:@"Title Here"
                                                             delegate:self
                                                    cancelButtonTitle:nil
                                               destructiveButtonTitle:nil
                                                    otherButtonTitles:nil];

    // ObjC Fast Enumeration
    for (NSString *title in array) {
        [actionSheet addButtonWithTitle:title];
    }

    actionSheet.cancelButtonIndex = [actionSheet addButtonWithTitle:@"Cancel"];

    [actionSheet showInView:self.view];

精确输出

只需循环并将操作添加到 ActionSheet

@IBAction func ClickAction(_ sender: Any) {

    let actionSheetAlertController: UIAlertController = UIAlertController(title: nil, message: nil, preferredStyle: .actionSheet)

    for title in self.titleData {
      let action = UIAlertAction(title: title.status, style: .default) { (action) in
        print("Title: \(title.id)")
      }

      let icon = UIImage.init(named: title.icon)

      action.setValue(icon, forKey: "image")
      action.setValue(CATextLayerAlignmentMode.left, forKey: "titleTextAlignment")

      actionSheetAlertController.addAction(action)
    }

    let cancelActionButton = UIAlertAction(title: "Cancel", style: .cancel, handler: nil)
    actionSheetAlertController.addAction(cancelActionButton)

    self.present(actionSheetAlertController, animated: true, completion: nil)
  }
