ios - 将数组传递给单例(swift)

Question

class MySingleton{
    static let shareInstance = MySingleton()
    private init() {}

    var myDetail = [Detail]() 
}

class DetailTableViewController {

     var expense = [Detail]()

  override func viewDidLoad() {
    super.viewDidLoad()

   ... put stuff in expense array ....


      MySingleton.shareInstance.myDetail = expense  //<--- doesn't work
      // error is "cannot assign value of type '[Detail]' to type [MySingleton.Detail]" 
  }
}

如何将数组复制到 MySingleton？现在我只是使用 segue 在我的类中传递数组

Answer 1

根据您的错误，您可能定义了 Detail 两次，一次在单例本地定义，一次为 viewController 全局定义。
