How to use swiftyjson to parse json data to foundation object and loop through data - swift

Question

So I'm trying to get his raw json data and use it to ultimately be viewed in a table(so one table cell would be --> Emirates - $1588.77)
Problem: Having trouble parsing the JSON data.. alamofire apparently does it automatically? but im completely confused with the data types. I keep getting weird errors like 'doesnt have a member named subscript" (I've also got swiftyjson installed but aa non-swiftyjson solution should work as well.
Code:
request(qpxRequest).responseJSON { (request, response, json, error) -> Void in
if response != nil {
//println(response!)
}
if json != nil {
// 1. parse the JSON data into a Foundation object
// 2. Grab the data from the foundation object (so its can be looped though in a table)
}
{
trips = {
data = {
carrier = (
{
name = "Cathay Pacific Airways Ltd.";
},
{
name = Emirates;
},
{
name = "Ethiopian Airlines Enterprise";
},
{
name = "Qantas Airways Ltd.";
},
{
name = "South African Airways";
}
);
};
tripOption = (
{
saleTotal = "AUD1537.22";
},
{
saleTotal = "AUD1588.77";
},
{
saleTotal = "AUD1857.42";
},
{
saleTotal = "AUD1857.42";
},
{
saleTotal = "AUD1922.42";
}
);
};
}
-------- Edit.
Using this model.
class FlightDataModel {
var carrier: String
var price: String
init(carrier: String?, price: String?) {
self.carrier = carrier!
self.price = price!
}
}
How woudl I use your solution to add it to an array of FlightDataModel class
This my my attempt..
var arrayOfFlights : [FlightDataModel] = [FlightDataModel]()
if let tripOptions = trips["tripOption"] as? [[String:AnyObject]] {
for (index, tripOption) in enumerate(tripOptions) {
//println("\(index): " + (tripOption["saleTotal"]! as String))
self.arrayOfFlights[index].carrier = tripOption["saleTotal"]! as String
println("\(self.arrayOfFlights[index].carrier)")
}

Alamofire can do it, but you have to dig into your JSON structure. :)
Like this, using Alamofire's responseJSON method:
Alamofire.request(.GET, YOUR_URL, parameters: nil, encoding: .URL).responseJSON(options: NSJSONReadingOptions.allZeros) { (request, response, json, error) -> Void in
if let myJSON = json as? [String:AnyObject] {
if let trips = myJSON["trips"] as? [String:AnyObject] {
if let data = trips["data"] as? [String:AnyObject] {
if let carriers = data["carrier"] as? [[String:String]] {
for (index, carrierName) in enumerate(carriers) {
println("\(index): " + carrierName["name"]!)
}
}
}
if let tripOptions = trips["tripOption"] as? [[String:AnyObject]] {
for (index, tripOption) in enumerate(tripOptions) {
println("\(index): " + (tripOption["saleTotal"]! as! String))
}
}
}
}
}
Output:
0: Cathay Pacific Airways Ltd.
1: Emirates
...
0: AUD1537.22
1: AUD1588.77
...
It's a bit easier with SwiftyJSON indeed. And for diversity's sake, we'll use Alamofire's responseString method this time:
Alamofire.request(.GET, YOUR_URL, parameters: nil, encoding: .URL).responseString(encoding: NSUTF8StringEncoding, completionHandler: {(request: NSURLRequest, response: NSHTTPURLResponse?, responseBody: String?, error: NSError?) -> Void in
if let dataFromString = responseBody!.dataUsingEncoding(NSUTF8StringEncoding, allowLossyConversion: false) {
let json = JSON(data: dataFromString)
let carriers = json["trips"]["data"]["carrier"].array
for (index, carrier) in enumerate(carriers!) {
println("\(index):" + carrier["name"].string!)
}
let tripOption = json["trips"]["tripOption"].array
for (index, option) in enumerate(tripOption!) {
println("\(index):" + option["saleTotal"].string!)
}
}
})
Output:
0: Cathay Pacific Airways Ltd.
1: Emirates
...
0: AUD1537.22
1: AUD1588.77
...
Note: I've used enumerate as an example for how getting the index of the content at the same time you get the content.
