私は目的のCのNSDictionaryに解析した後、JSONから "lat"と "lng"の値を抽出したいと思います。

html_attributions" : [], 
    "results" : [ 
     { 
     "geometry" : { 
      "location" : { 
       "lat" : 51.4994796, 
       "lng" : -0.1248094 
      } 
     },

     { 
     "geometry" : { 
      "location" : { 
       "lat" : 51.5058337, 
       "lng" : -0.1167623

は

for(NSDictionary *dictionary in parentDictionary[@"results"]){ 
    NSDictionary *location=dictionary[@"geometry"][@"location"]; 
    NSLog(@"Lat = %f, Lng = %f",[location[@"lat"] floatValue],[location[@"lng"] floatValue]); 
}
