我遇到一些json数据的麻烦。我正在制作一个天气应用程序,我解析的大部分信息都适用但天气
这是整个json数据的议会输出,这是我遇到麻烦的部分
json的完整输出
{
base = stations;
clouds = {
all = 90;
};
cod = 200;
coord = {
lat = "39.74";
lon = "-104.98";
};
dt = 1427305893;
id = 5419384;
main = {
humidity = 84;
pressure = 1022;
temp = "274.07";
"temp_max" = "275.35";
"temp_min" = "272.15";
};
name = Denver;
rain = {
1h = "0.25";
};
snow = {
1h = "0.17";
};
sys = {
country = US;
id = 532;
message = "0.07829999999999999";
sunrise = 1427288058;
sunset = 1427332632;
type = 1;
};
visibility = 4023;
weather = (
{
description = "light rain";
icon = 10d;
id = 500;
main = Rain;
},
{
description = snow;
icon = 13d;
id = 601;
main = Snow;
},
{
description = fog;
icon = 50d;
id = 741;
main = Fog;
},
{
description = mist;
icon = 50d;
id = 701;
main = Mist;
}
);
wind = {
deg = 20;
gust = "14.9";
speed = "12.9";
};
} 我也打印了钥匙
[base, id, dt, snow, main, coord, sys, wind, weather, visibility, clouds, cod, name, rain]
我试图将它保存为数组但是当我将arry [0]设置为字符串时它会崩溃
我的函数代码
func populateLabels(weatherData: NSData){
var jsonError: NSError?
let json = NSJSONSerialization.JSONObjectWithData(weatherData, options: nil, error: &jsonError) as NSDictionary
println(json)
if let city = json["name"] as? String {
CityName.text = city
}
println(json.allKeys)
if let coord = json["coord"] as? NSDictionary {
if let longi = coord["lon"] as? Double {
long.text = String(format: "%.2f", longi)
}
if let lati = coord["lat"] as? Double {
lat.text = String(format: "%.2f", lati)
}
}
if let main = json["main"] as? NSDictionary {
if let temper = main["temp"] as? Double {
temp.text = String(format: "%.2f", temper)
}
}
如果有人知道如何获得令人敬畏的描述 谢谢js
答案 0 :(得分:1)
我明白了...感谢blacksquare,larme,chirag90的帮助
if let tasks = json["weather"] as? NSArray
{
if let task = tasks[0] as? NSDictionary
{
if let taskName = task["description"] as? NSString
{
println(taskName)
}
}
}
