arrays - 如何按升序排列一个字典数组，然后对其他数组重新排序？

Question

我正在尝试对一本字典(类型为[String:[String]])进行排序，以便一个键按升序排列，一旦对键进行排序，我也想对其他数组进行排序。

这就是我的意思。

var dictionary = ["timeStamp":[String],"condition":[String]] //Dict to sort
dictionary["timeStamp"] = ["123","345","456","234"]
dictionary["condition"] = ["dry","wet","very wet","dry"]
dictionary["timeStamp"] = dictionary["timeStamp"]!.sort()
print("\(dictionary["timeStamp"]!)") //Returns["123","234","345","456"]

我如何才能将dictionary["condition"]排序为["dry","dry","wet","very wet"] ？

Answer 1

我会创建一个简单的结构，以便将您的属性关联起来并可以一起排序

struct condition {
    var timeStamp: Int
    var description: String
}

var conditionArray = [condition]()
conditionArray.append(condition(timeStamp: 123, description: "dry"))
conditionArray.append(condition(timeStamp: 345, description: "wet"))
conditionArray.append(condition(timeStamp: 456, description: "very wet"))
conditionArray.append(condition(timeStamp: 234, description: "dry"))
let sortedArray = conditionArray.sort() {return $0.timeStamp < $1.timeStamp}
