如何在Swift代码中获取引用参数的变量名？ var银行账户余额=3000000.00 var macbookpro=191000.00 var iphone6sPlus=59000.00 var newSweetHome=3500000.00 var AmoUnrequired=00.00 func purchaseItem1（当前余额：双倍，项目价格：双倍）->Double{ 如果（itemPrice

你不能。你考虑过用字典来代替吗

let items=[“MacBook Pro”：191000.0，“iPhone 6S Plus”：59000.0”]

或者您可能真的应该在某种数据结构中对这些信息进行编码，例如

var bankAccountBalance = 3000000.00
var macbookpro = 191000.00
var iphone6sPlus = 59000.00
var newSweetHome = 3500000.00
var amountRequired = 00.00

func purchaseItem1(currentBalance : Double, itemPrice : Double) ->Double {
    if(itemPrice<=currentBalance)
    {
        print("Purchased item for :\(itemPrice)")
        print("Your current outstanding Account balance is \(currentBalance)")

        return currentBalance-itemPrice   
    }
    else {
        amountRequired = itemPrice - currentBalance

        print("You dont have enough account balance to purchase this item :( ")
        print("You need \(amountRequired)Rs in your bank")
        return amountRequired
    }
}

purchaseItem1(currentBalance: bankAccountBalance, itemPrice: macbookpro)
purchaseItem1(currentBalance: bankAccountBalance, itemPrice: iphone6sPlus)
purchaseItem1(currentBalance: bankAccountBalance, itemPrice: newSweetHome)

我想得到项目的名称，它是变量名，并作为参数传递到函数中。你真的不清楚你在问什么。sir@Alexander我要求从函数purchaseItem1中传递的参数中获取变量名（currentBalance:Double，itemPrice:Double）.我想打印函数中传递参数的名称。非常感谢，先生。我是swift新手，刚刚开始学习swift。

struct Item {
    var name: String
    var price: Double
}

let items = [
    Item(name: "MacBook Pro", price: 191000), 
    Item(name: "iPhone 6S Plus", price: 59000)
]
