我有来自网站的JSON数据。我制作了主词典,并且可以解析除一个子词典之外的所有数据。我收到错误消息:“迅速:无法将类型’__NSCFArray’的值强制转换为’NSDictionary’”
我的数据的这个例子。我无法解析 “天气”, 但可以解析所有其他字典,例如"wind"。
"wind"
["name": Mountain View, "id": 5375480, "weather": ( { description = "sky is clear"; icon = 01n; id = 800; main = Clear; } ), "base": cmc stations, "wind": { deg = "129.502"; speed = "1.41";
程式码片段
let windDictionary = mainDictionary["wind"] as! [String : AnyObject let speed = windDictionary["speed"] as! Double print(speed) let weather = mainDictionary["weather"] as! [String : AnyObject] print(weather)
代表您的评论…我会说windDictionary是Dictionary …
Dictionary denotes in JSON with {} and Array denotes with [] // In printed response you may have array with ()
所以,您的天气部分是字典数组…您必须像解析它一样
let weather = mainDictionary["weather"] as! [[String : AnyObject]] // although please not use force unwrap .. either use `if let` or `guard` statement
