I have this JSON response string:
{"d":"{\"ID_usuario\":\"000130\",\"Nombre\":null,\"Vipxlo\":0,\"Provmun\":null,\"Descuentos\":null,\"Listaviplocal\":null}"}`
With this code:
- (void)connectionDidFinishLoading:(NSURLConnection *)connection
{
//Check valid signal
connection = nil;
NSString *responseString = [[NSString alloc] initWithData:responseData encoding:NSUTF8StringEncoding];
//data =nil;
NSArray *jsonArray = [responseString JSONValue];
How can I do it?
When you can afford to require iOS 5 you should try NSJSONSerialization .
Your code could look like this but I suggest reading the Docs first.
NSArray* jsonArray = [NSJSONSerialization JSONObjectWithData:responseData options:NSJSONReadingMutableLeaves error:someError]
This JSON should result in a Dictionary
NSDictionary *jsonDict = [responseString JSONValue];
then use:
[jsonDict objectForKey:@"d"];
Try using the SBJasonParser library for iOS.
You can then use this code (for all iOS versions):
SBJsonParser* parser = [[[SBJsonParser alloc] init] autorelease];
NSDictionary* myDict = [parser objectWithString: responseString];
Note: Your code above has a JSON Dictionary but you were trying to access it as an Array.
