json - 如何将字符串作为 json 转换为简单字符串 - SwiftyJSON

Question

我有一个像这样的 json 字符串:

[
  "http:\/\/kashanmap.ir\/media\/k2\/galleries\/6861\/A.jpg",
  "http:\/\/kashanmap.ir\/media\/k2\/galleries\/6861\/B.jpg",
  "http:\/\/kashanmap.ir\/media\/k2\/galleries\/6861\/C.jpg"
]

我想将其转换为字符串(用逗号分隔):

http://kashanmap.ir/media/k2/galleries/6861/A.jpg,http://kashanmap.ir/media/k2/galleries/6861/B.jpg,http://kashanmap.ir/media/k2/galleries/6861/C.jpg

<小时/>

let json = JSON(stringLiteral: urls)

但在打印 json 变量后，它显示:

[
  "http:\/\/kashanmap.ir\/media\/k2\/galleries\/3156\/A.jpg",
  "http:\/\/kashanmap.ir\/media\/k2\/galleries\/3156\/B.jpg",
  "http:\/\/kashanmap.ir\/media\/k2\/galleries\/3156\/C.jpg",
  "http:\/\/kashanmap.ir\/media\/k2\/galleries\/3156\/D.jpg"
]

尝试使用带有逗号分隔符的连接函数

let stringArrayCities = ["Reno", "Austin", "Miami"]
let combinedstringArrayCitiesComma = stringArrayCities.joined(separator: ",")
print(combinedstringArrayCitiesComma)
// prints Reno,Austin,Miami
