如何从Swift中的NSDictionary获取单独的String数组中的所有键和值？ [英] How to get all keys and values into separate String arrays from NSDictionary in Swift?

问题描述

    let urlAsString = "https://drive.google.com/uc?export=download&id=0B2bvUUCDODywWTV2Q2IwVjFaLW8"
    let url = NSURL(string: urlAsString)!
    let urlSession = NSURLSession.sharedSession()

    let jsonQuery = urlSession.dataTaskWithURL(url, completionHandler: { data, response, error -> Void in
        do {
            if let jsonDate = data, let jsonResult = try NSJSONSerialization.JSONObjectWithData(jsonDate, options: []) as? NSDictionary {

                print(jsonResult)

            }
        } catch let error as NSError {
            print(error)
        }


    })
    jsonQuery.resume()

好的，我在这里接收来自在线json的数据，然后将其存储为jsonresult中的NSDictionary。我需要将所有键和值分成两个独立的数组？

Okay so here i am receiving data from online json then storing it as NSDictionary in jsonresult . I need to get all keys and values as into two separate arrays ?

基本上我想要这个

jsonresult.allkeys - > String array

jsonresult.allvalues - > String array

推荐答案

你可以使用：

let keys = jsonResult.flatMap(){ $0.0 as? String }  
let values = jsonResult.flatMap(){ $0.1 }
