arrays - 快速制作一个数组数组

Question

所以我的代码一直有问题，特别是在我有这些数组的地方:

var messageIntents = ["Send a message", "Send message", "Text", "Send text", "Send a text"]
var weatherIntents = ["weather", "what's the weather", "how's the weather", "the weather"]
var musicIntents = ["play", "i want to hear", "shuffle"]

目标是检查字符串是否等于数组中的值之一。我不想一个一个地检查这些数组，而是想制作一个数组来检查它们。那可能吗？我将如何检查它？

您可以像这样 [[Any]] 简单地将数组添加到数组内部。

    var messageIntents = ["Send a message", "Send message", "Text", "Send text", "Send a text"]
    var weatherIntents = ["weather", "what's the weather", "how's the weather", "the weather"]
    var musicIntents = ["play", "i want to hear", "shuffle"]

下面是数组占位符内的数组示例。

    var arraysOfArray = [messageIntents, weatherIntents,musicIntents]

您可以通过每次循环数组的索引来访问对象

arraysOfArray[index]
arraysOnArray[0] //prints ["Send a message", "Send message", "Text", "Send text", "Send a text"]

或者像这样使用'for each'语句

for array in arraysOfArray{
    print(array)
   for dataObject in array{
    print(dataObject)
   }
 }
