one more doubt: i have got 13.00419814 77.66045468 from current location and i did revere geocode for it so that i got above address. but in that response i did not find these lat and long in json response — Murali mohan Proddatur

This one the value with key location

location = { lat = "13.0048165"; lng = "77.6600505"; };

The provide data is a Dictionary (with key results). Derived value from results is an array which holds all possible places from API. Each place (an object at index of array) is dictionary which have a sub Dictionary with key geometry. In this dictionary you have another dictionary which hold your location dictionary with lat and lng.

if i am not wrong it will be something like this

NSDictionary *aPlace=[[dict objectForKey:@"results"] objectAtIndex:someIndex];
NSDictionary *geomatry=[aPlace objectForKey:@"geometry"];
NSDictionary *location=[geomatry objectForKey:@"location"];
float lat=[[location objectForKey:@"lat"] floatValue ];
float lng=[[location objectForKey:@"lng"] floatValue ];

Which latitude and longitude has to taken?
