ios - map geocode API gives Null response -

-

i'm using below code getting geocode response of particular address,

    nsstring *address = @"doha,qatar";     nslog(@"address : %@",address);     nsstring *esc_addr = [address stringbyaddingpercentescapesusingencoding: nsutf8stringencoding];     nsstring *req = [nsstring stringwithformat: @"http://www.maps.google.com/maps/api/geocode/json?address=%@&sensor=false", esc_addr];      nsurl *url=[nsurl urlwithstring:req];     nslog(@"url : %@",url);     nsdata *data=[nsdata datawithcontentsofurl:url];     nslog(@"data : %@",data);     nserror *error=nil;     id response=[nsjsonserialization jsonobjectwithdata:data options:                  nsjsonreadingmutablecontainers error:&error];      nslog(@"the json object: %@ or error is: %@", response, error);

but response null.

the response,

2014-11-27 16:35:48.961 myproj[15279:254055] address : doha,qatar 2014-11-27 16:35:48.961 myproj[15279:254055] url : http://www.maps.google.com/maps/api/geocode/json?address=doha,qatar&sensor=false 2014-11-27 16:35:49.005 myproj[15279:254055] data : (null) 2014-11-27 16:35:49.008 myproj[15279:254055] *** terminating app due uncaught exception 'nsinvalidargumentexception', reason: 'data parameter nil'

but when open url in brows gives output as,

i tested code , works fine.

data parameter not null.it contains info of json.

so,maybe have check these

  1. the version of google maps sdk(i use 1.8.0.8950-not newest)
  2. the initialization of gms services
  3. your api key google maps.
