Question

请问swift下，如何可以把类对象转成json

如：
class user
{
var name:String
var age:Int
init(_name:String,_age:Int)
{
self.name = _name
self.age = _age
}
}
let myuser = user(_name: "abc", _age: 15)
//let isok = NSJSONSerialization.isValidJSONObject(myuser)
//print(isok)
do {
let jsonData = try NSJSONSerialization.dataWithJSONObject(myuser, options: NSJSONWritingOptions())
let str = NSString(data: jsonData, encoding: NSUTF8StringEncoding)
print(str!)
}catch
{
}

Answer 1

let jsonData = try NSJSONSerialization.dataWithJSONObject(myuser, options: NSJSONWritingOptions())
let str = NSString(data: jsonData, encoding: NSUTF8StringEncoding)
print(str!)

很对啊！
