【问题描述】：

我是 Swift 新手。我正在制作购物清单应用程序。有两个 UITextField，一个用于项目名称，另一个用于保存到字典的项目数量。我想与 UIActivityViewController 共享这个列表，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)
    

【参考方案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
  

在你的类中声明变量

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)

【参考方案2】：

试试这个：-

     @IBAction func share(_ sender: UIButton) 
      let activityVc = UIActivityViewController(activityItems: ["here your item name","item quantity"], applicationActivities:nil)

    activityVc.popoverPresentationController?.sourceView = self.view
    self.present(activityVc, animated:true, completion:nil)
