how to extract a json object using swift? - ios

Question

JSON function:
func extract_json(data:NSString){
var parseError: NSError?
let jsonData:NSData = data.dataUsingEncoding(NSASCIIStringEncoding)!
let json: AnyObject? = NSJSONSerialization.JSONObjectWithData(jsonData, options: NSJSONReadingOptions.MutableContainers, error: &parseError)
if (parseError == nil){
if let coupon_list = json as? [String: AnyObject]{
if let coupons = coupon_list["data"] as? [AnyObject]{
for (var i = 0; i < coupons.count ; i++ ){
if let coupon_obj = coupons[i] as? NSDictionary{
let location: AnyObject? = coupon_obj.objectForKey("location")
//the print the value location
println(location)
//I just want to get the number keys before the value of the location
this is my Json object where you can see that
{
brand = "Mang Inasal";
category = (
2
);
desc = "Mang Inasal Salmonella Giveaway";
discount = 50;
"end_date" = 1443369600;
id = 2;
imgs = (
"http://mymegamobile.com/savvy/halo2x.png",
"http://mymegamobile.com/savvy/bar_filter.png",
"http://mymegamobile.com/savvy/bar_mega.png",
"http://mymegamobile.com/savvy/box1.png",
"http://mymegamobile.com/savvy/box2.png"
);
location = {
1435307555 = Baguio;
};
name = "Mang Inasal Halo Halo";
stamp = "2015-09-02 14:04:38";
"start_date" = 1438012800;
}
the result of the object structure is above.
How can I get the value of 1435307555 in my location?

Answer 1

You can do it this way:
let yourObject = location?.objectForKey("165952298") as! String

Answer 2

for (key,value) in coupon_list {
println(key)
}
This way you'll get all keys from the JSON

let jsonData:NSData = data.dataUsingEncoding(NSASCIIStringEncoding)!
let json: AnyObject? = NSJSONSerialization.JSONObjectWithData(jsonData, options: NSJSONReadingOptions.MutableContainers, error: &parseError) as! NSDictionary
if (parseError == nil) {
for (var i = 0; i < json.count ; i++ ) {
let location: AnyObject? = ((json)["location"] as! NSDictionary)["1435307555"]
//the print the value location
