I need to create a JsonString from a NSString, without any key in ObjC. All tutorials talks about serialization from NSDictionary or NSData.
My string is like @"fr-FR". The result i'm looking for is like @"{"fr-FR"}", but dynamically. Can't do it myself because i will need to do the same stuff for different kind of arguments.
Thanks in advance :)
To achieve the result you are asking for (even if it's not a proper JSON) you could try something like this:
NSString *myString = @"fr-FR"; // Or whatever
NSString *result = [NSString stringWithFormat:@"{\"%@\"}", myString];
You need to use a JSON framework/library, for example TouchJSON, and then you can do the following to encode your NSString:
theData = [[CJSONSerializer serializer] serializeObject:theString
error:&theError];
(from the demo code here).
You could use NSJSONSerialization class if you develop on IOS 5 +
create data with your string
NSString *myString = @"fr-FR"; // Or whatever
NSString *result = [NSString stringWithFormat:@"{%@}", myString];
NSData* data=[result dataUsingEncoding:NSUTF8StringEncoding];
and then use
+ (id)JSONObjectWithData:(NSData *)data options:(NSJSONReadingOptions)opt error:(NSError **)error
to create your JSON object
(just typed, not tested)
IMHO after reading the json spec again ( http://www.json.org ) {"string"} isn't valid json and the code you are using in c# produces invalid results. However, if you need to communicate with c# code that acts this way you should just encode the string itself using a JSON library and then afterwards pack it in curly braces. That way you get all the escaping needed for JSON for special cases (e.g. quotes and whatnot) which you don't if you just add quotes and braces manually.
