swift - 在 Swift 中与 UIActivityViewController 共享字典

Question

我是 Swift 的新手。我正在制作购物 list 应用程序。有两个UITextField，一个是元素名称，一个是保存到字典的元素数量。我想与 UIActivityViewController 共享此列表，但它只共享最后一个值。有人可以建议我如何与 UIActivityViewController 共享所有项目和金额。

var shoppinglist = [String:String]()

@IBOutlet weak var Item: UITextField!

@IBOutlet weak var Amount: UITextField!

@IBAction func Add(_ sender: UIButton) {
    var item = Item.text!
    var amount = Amount.text!
    shoppinglist [item] = amount
    print(shoppinglist)
     }

@IBAction func share(_ sender: UIButton) {

    let activityController = UIActivityViewController(activityItems: [shoppinglist], applicationActivities: nil)
    present(activityController,animated: true,completion: nil)
    }
}

Answer 1

试试下面的代码。我希望这个编码对你有所帮助。

class shoppinglist:NSObject {
var yourItem:String = ""
var amount:Int = 0
  init(yourItem:String, amount:Int) {
    self.yourItem = yourItem
    self.amount = amount
  }
}

在类中声明变量

var shoppingListArray = [shoppinglist]()
@IBOutlet weak var Item: UITextField!
@IBOutlet weak var Amount: UITextField!

@IBAction func Add(_ sender: UIButton) {
   self.shoppingListArray.append(shoppinglist(yourItem:Item.text, amount:Int(Amount.text!)!))
   print(shoppingListArray)
}

@IBAction func share(_ sender: UIButton) {
  let activityController = UIActivityViewController(activityItems: shoppingListArray, applicationActivities: nil)
  present(activityController,animated: true,completion: nil)
}
}
