Question

由于我是swift的新手，我想对 cityName 键进行排序。

var arrCityList: [[String: Any]] = []

CityList：

[["pk_cityID": 1, "cityName": Ahmedabad], ["pk_cityID": 25, "cityName": Dahod], ["pk_cityID": 39, "cityName": Antah], ["pk_cityID": 44, "cityName": Bahror], ["pk_cityID": 117, "cityName": Jahazpur]]

arrCityList包含 CityList 类型的数据。

我做了很多 SOF ，但我没有找到答案。

有人请帮助我找到解决方案，因为我被困在这上面。

先谢谢。

Answer 1

你可以尝试

var arrCityList: [[String: Any]] = [["pk_cityID": 1, "cityName": "Ahmedabad"], ["pk_cityID": 25, "cityName": "Dahod"], ["pk_cityID": 39, "cityName": "Antah"], ["pk_cityID": 44, "cityName": "Bahror"], ["pk_cityID": 117, "cityName": "Jahazpur"]]

arrCityList.sort { ($0["cityName"] as! String) < ($1["cityName"] as! String) }

print(arrCityList)

Answer 2

var arrCityList = [[String: Any]]()

arrCityList.append(["pk_cityID": 1, "cityName": "Ahmedabad"])
arrCityList.append(["pk_cityID": 25, "cityName": "Dahod"])
arrCityList.append(["pk_cityID": 39, "cityName": "Antah"])
arrCityList.append(["pk_cityID": 44, "cityName": "Bahror"])
arrCityList.append(["pk_cityID": 117, "cityName": "Jahazpur"])


arrCityList.sort {
  let cityNameA = $0.0["cityName"] as! String
  let cityNameB = $0.1["cityName"] as! String

  return cityNameA < cityNameB
}


print(arrCityList)
// [
//   ["pk_cityID": 1, "cityName": "Ahmedabad"], 
//   ["pk_cityID": 39, "cityName": "Antah"], 
//   ["pk_cityID": 44, "cityName": "Bahror"], 
//   ["pk_cityID": 25, "cityName": "Dahod"], 
//   ["pk_cityID": 117, "cityName": "Jahazpur"], 
//   ["pk_cityID": 117, "cityName": "Jahazpur"]
// ]

在swift 3.0中按字母顺序排序数组[[String：Any]]
