如何将字符串转换为json到简单字符串-SwiftyJSON

我有一个json字符串，如下所示：

[
  "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）：

---

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联接函数

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

---

让json=json（stringLiteral:url）

这是一个数组。然后，您可以看到不是真正的答案，但如果您可以等待Swift 4，Swift对象和json之间的转换将内置到该语言中。好的，现在如何将字符串转换为数组？可能是

[
  "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"
] 

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