如何使用swift将json的数组转换为数组

Question

我有这个数组items

var items: [String] = []

而prizes[0]是__NSCFDictionary

其中一个键值对是

键：to_prizes

值：

Optional(<__NSCFArray 0x787dbfb0>(
94761178,
71959593,
36665808,
54185273,
18953944,
347,
790
)

我怎样才能使swift字符串数组items成为[94761178，....，790]

Answer 1

您可以像这样访问此路径：

let prizesDictionary = prizes[0] as NSDictionary
let toPrizesArray = prizesDictionary["to_prizes"] as NSArray
var items: [String] = toPrizesArray as [AnyObject] as [String]
