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:@","];
}
