我在使用json生成的NSDictionary时遇到问题。我不知道我的NSDictionary有什么问题，这意味着我在NSDictionary中没有得到像json这样的排序键当我试图输出它时。请帮助
这是我在intellij IDEA REST工具中测试过的json

正如您所看到的那些按键带有0,1_190,2_69,3_61,4_86等，其值为“All Venues，AEP Gifu，ARAI Bayside”（按字母顺序排列为A，B，C，D） ...）“

如你所见，它不像我之前的json。我不知道为什么以及如何获得这样的数据。如果我想得到像json那样排序的相同数据，我该怎么做？请帮助....我已经坚持这个问题两天了。我还没有答案。我尝试了所有的排序方法，我的键和值仍然无效。希望这段代码可以帮助。
var venueValue = [String]()
var venue = [String:String]()
var selectedValue : String?
override func viewDidLoad() {
self.setNavigationBarItem()
self.venuePicker!.hidden = true
self.venueTxt?.delegate = self
self.venuePicker?.delegate = self
var request = NSMutableURLRequest(URL: NSURL(string: "http://dev.colay.net/ws/m/autos/global/venues")!)
var session = NSURLSession.sharedSession()
request.HTTPMethod = "POST"
var err: NSError?
let task = session.dataTaskWithRequest(request, completionHandler: {data, response, error -> Void in
println("Auction : Request Completed")
var err: NSError?
if error == nil{
var venues = NSJSONSerialization.JSONObjectWithData(data, options:nil, error: &err) as! NSDictionary
for (k, v) in venues {
if let value = v as? [String] {
//println(value)
// Acutally value should start from "All Venue".I wonder why it start at "ZeroCentral",Please check my output.
self.venueValue.append(value[0])
}
}
self.venueValue.sort(<)
println(self.venueValue)
}
else{
println(error.localizedDescription)
}
if(err != nil) {
// If there is an error parsing JSON, print it to the console
println("JSON Error \(err!.localizedDescription)")
}
})
task.resume()
}
[更新]我尝试输出的NSDictionary的值在快速期间按升序排序从this开始。但是，我希望“所有场地”开始而不是“AEP Gifu”。如何做我需要做什么？
答案 0 :(得分：1)
如果顺序很重要，则不能依赖NSDictionary，因为它的键是任意的。
要解决此排序问题，您可能希望使用数组。
所以将你的json结构改为：
{
"data":[
{"0":["All Venues"]},
{"1_190":["AEP Gifu"]},
{"2_69":["ARAI Bayside"]}
]
}
转换后，您将拥有[String:[[String:[String]]]]结构。
let jsonDict = ... as! [String:[[String:[String]]]]
let data = jsonDict["data"]! // [[String:[String]]]
for a in data {
let key = a.keys.first!
let value = a[key]! // [String]
for string in value {
println(string)
}
}
// Prints out:
// All Venues
// AEP Gifu
// ARAI Bayside
