Swift 从字典中获取值

Question

请帮我从响应中获取值

{
  "BU": {
    "name": "Bulawayo",
    "names": "Bulawayo"
  },
  "HA": {
    "name": "Harare",
    "names": "Harare"
  }
}

我想要键名的值。我的代码在下面

let response = responseObject as! Dictionary<String,AnyObject>
let stateNames = response.values as! Dictionary<String,AnyObject>

遇到这个问题:

cannot cast from lazyMapCollection<Dictionary<String,Anyobject>,String> in swift

Answer 1

您可以获得“BU”的值作为response.valueForKey("BU").valueForKey("name")，它将为您提供值“Bulawayo”。
