The string to convert:
[{"description": "Hi","id":2,"img":"hi.png"},{"description": "pet","id":10,"img":"pet.png"},{"description": "Hello! :D","id":12,"img":"hello.png"}]
转换字符串的代码:
var json = JSON(stringLiteral: stringJSON)个
字符串被转换为JSON，当我试图计算这个JSON中有多少块时(预期答案=3)，我得到0.
print(json.count)
Console Output: 0
我遗漏了什么？非常感谢您的帮助.
我用这种方法修好.
I will use the variable "string" as the variable what contains the JSON.
1.
用NSData对sting进行如下编码
var encodedString : NSData = (string as NSString).dataUsingEncoding(NSUTF8StringEncoding)!
取消编码编码的字符串(这听起来可能有点奇怪，呵呵):
然后你可以用这个JSON做任何你想做的事情.
比如，用
finalJSON.count or print(finalJSON[0]) or whatever you like to do.
