nsjsonserialization

I've read many Q/As on this problem but couldn't find an answer that fits my situation. I retrieve a JSON response from a REST service I've created in PHP. This is my code: NSURLResponse *response = nil; NSError *theError1 = nil; NSError *theError2 = nil; NSURL *webServiceUrl = [NSURL URLWithString:@"http://..."]; NSURLRequest *request = [NSURLRequest requestWithURL:webServiceUrl cachePolicy:NSURLRequestReturnCacheDataElseLoad timeoutInterval:30]; NSData *theData = [NSURLConnection sendSynchronousRequest:request returningResponse:&response error:&theError1]; NSString *dataString = [[NSString

I'm using FHSTwitterEngine to post a gif to twitpic. When I have a wifi or 3G connection on the iphone everything works fine. But I also want to implement some error handling for when there is no connection or when the upload failed. So for testing I put the iphone in airplane mode and try to upload to twitpic using the following method: id returned = [[FHSTwitterEngine sharedEngine] uploadImageToTwitPic:gif withMessage:@"message" twitPicAPIKey:@"key"]; but when I do that I immediately get the following error: Terminating app due to uncaught exception 'NSInvalidArgumentException', reason:

I'm getting this error while parsing JSON: NSDictionary *json = [NSJSONSerialization JSONObjectWithData:data options:NSJSONReadingMutableContainers error:&error]; Error Domain=NSCocoaErrorDomain Code=3840 "The operation couldn’t be completed. (Cocoa error 3840.)" (Unable to convert data to string around character 73053.) UserInfo=0x1d5d8250 {NSDebugDescription=Unable to convert data to string around character 73053.} Any suggestions how to fix this? ADDED As it says in error report, the parser can't go through the character at position 73053, which is "ø" in my JSON response. As far as I know

I have a classes that looks like this: class Foo { var bar = Int() } class Bar { var baz = String() var arr = [Foo]() } and I have an object of Bar structure that I need to serialize to JSON: let instance = Bar() What is the more elegant way to do it via standard library or some third-party libraries? Thanks in advance. I suggest taking this approach: class Foo { var bar = Int() } class Bar { var baz = String() var arr = [Foo]() var jsonDictionary: NSDictionary { return [ "baz" : self.baz, "arr" : self.arr.map{ $0.bar } ] } } let bar = Bar() bar.baz = "some baz" bar.arr.append(Foo()) var error

I'm try to set an NSDictionary to a JSON object retrieved from the server, I'm doing that in this line: _peopleArray = [NSJSONSerialization JSONObjectWithData:data options:0 error:nil]; It works fine and properly creates the dictionary. However, I have a problem, values that are null in the JSON object are stored as "<null>" string values in the dictionary. Is there any way to fix this or work around it? I want to avoid traversing through the entire thing and setting them to @"" . Thanks for any help! ~Carpetfizz There is nothing I guess, though it can be easily corrected from api makers, if

I am running a background NSURLSession session and i am trying to figure out a way to get the JSON response out of one of the NSURLDownloadTaskDelegate callbacks. I have configured my session to accept JSON responses. NSURLSessionConfiguration *backgroundSession = [NSURLSessionConfiguration backgroundSessionConfiguration:@"com.Att.Locker.BackgroundUpload"]; backgroundSession.HTTPAdditionalHeaders = @{ @"Accept":@"application/json"}; session = [NSURLSession sessionWithConfiguration:backgroundSession delegate:uploader delegateQueue:nil]; I can easily parse JSON response for

I created a WCF service, which provides the following response to my POST operation: "[{\"Id\":1,\"Name\":\"Michael\"},{\"Id\":2,\"Name\":\"John\"}]" My call to JSONObjectWithData, doesn't return any error, yet I can't enumerate over the results, what am I doing wrong? NSError *jsonParsingError = nil; NSMutableArray *jsonArray = [NSJSONSerialization JSONObjectWithData:data options:NSJSONReadingMutableContainers|NSJSONReadingAllowFragments error:&jsonParsingError]; NSLog(@"jsonList: %@", jsonArray); if(!jsonArray) { NSLog(@"Error parsing JSON:%@", jsonParsingError); } else { // Exception thrown

I have a JSON Data which looks like: [ { "Name" : "Ernst Handel", "City" : "Graz", "Country" : "Austria" }, { "Name" : "Wolski Zajazd", "City" : "Warszawa", "Country" : "Poland" } ] and I am converting it to NSDictionary using: var jsonResult: NSDictionary = NSJSONSerialization.JSONObjectWithData( data, options: NSJSONReadingOptions.MutableContainers, error: nil) as NSDictionary I usually use this. Works for both numeric and associative types of JSON. It works for your as well. I tried. func JSONParseArray(jsonString: String) -> [AnyObject] { if let data = jsonString.dataUsingEncoding
