JSON parsing issue - iphone

Question

My code:
NSString *jsonString;
jsonString = [[NSMutableString alloc] initWithData:responseData encoding:NSUTF8StringEncoding];
// Create a dictionary from the JSON string
NSDictionary *results = [jsonString JSONValue];
NSLog(#"%#",jsonString);
// Build an array from the dictionary for easy access to each entry
NSArray *places = [results objectForKey:#"description"];
I am not getting the result i wanted.
When I debug the code I am getting 2 key/value pair & 0 object for NSArray places.

Answer 1

It is correct that you have 2 key/value pairs. The top two keys intact are "predictions" and "status". So you must first of all extract predictions (it's an array):
NSArray *predictions = [results objectForKey:#"predictions"];
and then iterate over it; also note that "description" is a string and to get the places you must split it using the "," separator:
for(NSDictionary *aPrediction in predictions) {
NSString *description = [aPrediction objectForKey:#"description"];
NSArray *placesInDescription = [description componentsSeparatedByString:#","];
}

Answer 2

maybe you should use:
NSArray *places = [results valueForKey:#"predictions"];

Answer 3

Works for me without any problems with JSON Kit!
NSString *jsonString;
NSData *responseData = [NSData dataWithContentsOfURL: [NSURL URLWithString:#"https://maps.googleapis.com/maps/api/place/autocomplete/json?input=solapur&sensor=true&key=AIzaSyC0K5UhV_BWmXhncIZEnbh-WG2RVQVgfdY"]];
jsonString = [[NSMutableString alloc] initWithData:responseData encoding:NSUTF8StringEncoding];
// Create a dictionary from the JSON string
NSDictionary *results = [jsonString objectFromJSONString];
// Build an array from the dictionary for easy access to each entry
NSArray *places = [results valueForKey:#"predictions"];
NSLog(#"places %#", places);
