以JSON数组

Question

SWIFT访问我从JSON这个数据从OpenWeatherMap API

"weather":[{"id":500,"main":"Rain","description":"light rain","icon":"10d"}], 

我不知道如何访问属性“说明” ...... 我使用Alamofire和SwiftyJSON。

我从

"sys":{"type":1,"id":5091,"message":0.0237,"country":"GB","sunrise":1436673470,"sunset":1436732035} 

使用这段代码没有问题GET值：

var weatherJson = JSON(json!) 
var temperature = weatherJson["main", "temp"].double 
. 
. 
. 
func setLabels() { 

    if let temp = self.weather?.temp{ 
    //code 
    } 
} 

但不额外括号[]工作...

编辑： SOLUTION - >

func getWeatherData(urlString: String) { 
var weatherJson = JSON(json!) 
var description = weatherJson["weather"][0]["description"].stringValue 
} 


func setLabels() { 
    if let description = self.weather?.desc{ 
    self.descriptionLabel.text = description 
    } 
} 

• “类天气” 存储值

尝试像下面这样。

var descriptionString = jsonObj["weather"]![0]["description"]
