我有来自网站的JSON数据。我制作了主词典,我可以解析除一个子词典之外的所有数据。我收到错误“Swift:无法将类型'__NSCFArray'的值转换为'NSDictionary'”
我的数据示例。我无法解析“weather”,但我可以解析所有其他词典,例如"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";
代码片段
let windDictionary = mainDictionary["wind"] as! [String : AnyObject
let speed = windDictionary["speed"] as! Double
print(speed)
let weather = mainDictionary["weather"] as! [String : AnyObject]
print(weather)
答案 0 :(得分:15)
代表你的评论...我想说windDictionary是词典......
Dictionary denotes in JSON with {} and
Array denotes with [] // In printed response you may have array with ()
所以,你的天气部分是字典数组......你必须像
那样解析它 let weather = mainDictionary["weather"] as! [[String : AnyObject]] // although please not use force unwrap .. either use `if let` or `guard` statement
