转换阵列<String>为字符串，然后回到阵<String>

Question

说我有一个变量

let stringArray = "[\"You\", \"Shall\", \"Not\", \"PASS!\"]" 

// if I show this, it would look like this 
print(stringArray) 
["You", "Shall", "Not", "PASS!"] 

现在让我们有一个数组<字符串>

let array = ["You", "Shall", "Not", "PASS!"] 

// if I convert this into string 
// it would roughly be equal to the variable 'stringArray' 

if String(array) == stringArray { 
    print("true") 
} else { 
    print("false") 
} 

// output would be 
true 

现在说我应该怎么做才能转换变量“ stringArray'to'Array < String>'

Answer 1

答案将是使用NSJSONSerialization转换字符串

感谢Vadian为尖

let dataString = stringArray.dataUsingEncoding(NSUTF8StringEncoding) 
let newArray = try! NSJSONSerialization.JSONObjectWithData(dataString!, options: []) as! Array<String> 

for string in newArray { 
    print(string) 
} 

瞧你有它，它现在是一个字符串数组
