Question

在我的iOS应用程序中，我成功收到了以下json（我认为是json）：

{
    data =     {
        "current_condition" =         (
                        {
                cloudcover = 16;
                humidity = 59;
                "observation_time" = "09:09 PM";
                precipMM = "0.1";
                pressure = 1010;
                "temp_C" = 10;
                "temp_F" = 49;
                visibility = 10;
                weatherCode = 113;
                weatherDesc =                 (
                                        {
                        value = Clear;
                    }
                );
                weatherIconUrl =                 (
                                        {
                        value = "http://www.worldweatheronline.com/images/wsymbols01_png_64/wsymbol_0008_clear_sky_night.png";
                    }
                );
                winddir16Point = NW;
                winddirDegree = 316;
                windspeedKmph = 47;
                windspeedMiles = 29;
            }
        );
        request =         (
                        {
                query = "Lat 32.35 and Lon 141.43";
                type = LatLon;
            }
        );
        weather =         (
                        {
                date = "2013-01-15";
                precipMM = "1.8";
                tempMaxC = 12;
                tempMaxF = 53;
                tempMinC = 10;
                tempMinF = 50;
                weatherCode = 119;
                weatherDesc =                 (
                                        {
                        value = Cloudy;
                    }
                );
                weatherIconUrl =                 (
                                        {
                        value = "http://www.worldweatheronline.com/images/wsymbols01_png_64/wsymbol_0003_white_cloud.png";
                    }
                );
                winddir16Point = NNW;
                winddirDegree = 348;
                winddirection = NNW;
                windspeedKmph = 66;
                windspeedMiles = 41;
            },
                        {
                date = "2013-01-16";
                precipMM = "0.6";
                tempMaxC = 13;
                tempMaxF = 56;
                tempMinC = 11;
                tempMinF = 51;
                weatherCode = 113;
                weatherDesc =                 (
                                        {
                        value = Sunny;
                    }
                );

这里考虑的数据是什么？它是json对象的根？什么是现状？我想我需要解释如何解释这个json，所以我可以在tableview中显示它。我试图越过这个json tutorial，但那里的json完全不同！它使用＆＃34;：＆＃34;分开键值，但这个json没有它。我完全糊涂了

Answer 1

是的，看起来像JSON。看一下NSJSONSerialization课程。它的污垢很简单易用。您将JSONObjectWithData:options:error:方法传递给包含您要读取的JSON的NSData对象，并返回表示JSON数据＆＃34;对象图＆＃34;的Foundation类对象。在你的情况下，它看起来像顶级对象是一个字典，所以你应该得到一个NSDictionary。

Answer 2

看起来像是json。您可以通过这种方式操作数据。

id jsonData = [NSJSONSerialization JSONObjectWithData:data options:0 error:nil];
if ([greeting isKindOfClass:[NSDictionary class]]) {
    //manipulate dictionary
}else if ([greeting isKindOfClass:[NSArray class]]) {
//manipulate array
}else{
//manipulate other
}
