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?
基本上我想要这个
jsonresult.allkeys – >字符串数组
jsonresult.allvalues – >字符串数组
解决方法
您可以使用:
let keys = jsonResult.flatMap(){ $0.0 as? String }
let values = jsonResult.flatMap(){ $0.1 }
