轉換陣列<String>爲字符串，然後回到陣<String>

Question

說我有一個變量

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

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

現在讓我們有一個數組<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 

現在說我應該怎麼做才能轉換變量「 stringArray'to'Array < String>'

Answer 1

答案將是使用NSJSONSerialization轉換字符串

感謝Vadian爲尖

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，它現在是一個字符串數組
