如何进行json解析

Answer 1

data =
{
"results": [
{
"location": {
"id": "WS0E9D8WN298",
"name": "广州",
"country": "CN",
"path": "广州,广州,广东,中国",
"timezone": "Asia/Shanghai",
"timezone_offset": "+08:00"
},
"now": {
"text": "大雨",
"code": "15",
"temperature": "31"
},
"last_update": "2016-08-15T15:05:00+08:00"
}
]
}

    guard let jsonObject = try? NSJSONSerialization.JSONObjectWithData(data, options: NSJSONReadingOptions()) else {
        return
    }
    let results = jsonObject["results"]

                    let info = NSDictionary()
    for result in results {
        let location = result["location"] as! NSDictionary
        info.setValue(location["id"], forKey: "id")
        info.setValue(location["name"], forKey: "name")
        info.setValue(location["country"], forKey: "country")
        info.setValue(location["path"], forKey: "path")
        info.setValue(location["timezone"], forKey: "timezone")
        info.setValue(location["timezone_offset"], forKey: "timezone_offset")

        let now = result["now"] as! NSDictionary
        info.setValue(now["text"], forKey: "text")
        info.setValue(now["code"], forKey: "code")
        info.setValue(now["temperature"], forKey: "temperature")

        info.setValue(result["last_update"], forKey: "last_update")
    }

    print(info)
