I'm trying to do this, but I can't modify the JSON structure.
----------------------- import Foundation let s = "{ \"images\" : [ { \"thumb\" : \"url1\", \"width\" : 10 }, { \"thumb\" : \"url2\", \"width\" : 20 } ] }" let data = (s as NSString).dataUsingEncoding(NSUTF8StringEncoding)! do { if var json = try NSJSONSerialization.JSONObjectWithData(data, options: .MutableContainers) as? [String:AnyObject] { print("JSON: \(json)") if var images = json["images"] as? [[String:AnyObject]] { for var image in images { if let thumbURL = image["thumb"] { image["thumb"] = "FOOBAR: \(thumbURL)" print("new: \(image["thumb"])") } } let newData = try NSJSONSerialization.dataWithJSONObject(json, options: NSJSONWritingOptions(rawValue: 0)) let s2 = NSString(data: newData, encoding: NSUTF8StringEncoding) print(s2) } } } catch let e as NSError { print("Error parsing model.json: \(e)") } ----------------------- JSON: ["images": ( { thumb = url1; width = 10; }, { thumb = url2; width = 20; } )] new: Optional(FOOBAR: url1) new: Optional(FOOBAR: url2) Optional({"images":[{"thumb":"url1","width":10},{"thumb":"url2","width":20}]}) ----------------------- But it seems the way I drill down into the initial json dictionary gives me copies, or otherwise prevents me from modifying the dictionary like this. Any suggestions on what I can do? I really don't want to have to walk and rebuild the JSON myself. -- Rick Mann rm...@latencyzero.com _______________________________________________ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.
