ios - 来自多个循环的对象数组

Question

这个问题已经有答案了:

How can I run through three separate arrays in the same for loop? (6 个回答)

我想最终得到一组自定义对象。当我有多个数组需要迭代以创建自定义对象时，我很难找到解决此问题的方法。我有这样的东西:

class CustomObject {
    var name = ""
    var place = ""
    var price = ""
}

var nameArray = [“name1”,"name2","name3"]
var placeArray = [“place1”,"place2","place3"]
var priceArray [“price1”,"price2","price3"]
var customArray [CustomObject]()
createObject(name : nameArray, place : placeArray, price : priceArray)

func createObject(name : [String], place : [String], price : [String]) {
    let instance = CustomObject()
    for names in name {
        instance.name = names
    }
    for places in place {
        instance.place = places
    }
    for prices in price {
        instance.price = prices
        customArray.append(instance)
    }
}

我想最终得到一组自定义“实例”。现在我的代码为每个属性提供每个数组的最后一个索引。

你可以尝试，我也认为所有数组都有相同的计数

 var customArray = [CustomObject]()

  for  i in 0..<nameArray.count {

       let instance = CustomObject()

       instance.name = nameArray[i]

       instance.place = placeArray[i]

       instance.price = priceArray[i]

       customArray.append(instance)
 }
