MatrixDistance API from Google for iOS - ios

Question

I am trying to build an app with a map in which the user would select his origin address and destination address.. It all works fine, but I can't access the Google API Distance Matrix..
I am try with following:
NSString *urlPath = [NSString stringWithFormat:#"/maps/api/distancematrix/xml?origins=%#=%#&mode=driving&language=en-EN&sensor=false" ,polazisteField.text , odredisteField.text];
NSURL *url = [[NSURL alloc]initWithScheme:#"http" host:#"maps.googleapis.com" path:urlPath];
NSMutableURLRequest *request = [[[NSMutableURLRequest alloc]init]autorelease];
[request setURL:url];
[request setHTTPMethod:#"GET"];
NSURLResponse *response ;
NSError *error;
NSData *data;
data = [NSURLConnection sendSynchronousRequest:request returningResponse:&response error:&error];
NSString *result = [[NSString alloc] initWithData:data encoding:NSASCIIStringEncoding];
address.text = result;
, but have no luck, any idea how to resolve this?

I think your call has been considred as invalid API call.
try below code that is edited from your code snippet.
NSString *urlPath = [NSString stringWithFormat:#"/maps/api/distancematrix/json?origins=%#&destinations=%#&mode=driving&language=en-EN&sensor=false" ,polazisteField.text , odredisteField.text];
NSURL *url = [[NSURL alloc]initWithScheme:#"http" host:#"maps.googleapis.com" path:urlPath];
NSMutableURLRequest *request = [[NSMutableURLRequest alloc]init];
[request setURL:url];
[request setHTTPMethod:#"GET"];
NSURLResponse *response ;
NSError *error;
NSData *data;
data = [NSURLConnection sendSynchronousRequest:request returningResponse:&response error:&error];
NSMutableDictionary *jsonDict= (NSMutableDictionary*)[NSJSONSerialization JSONObjectWithData:data options:kNilOptions error:&error];
NSMutableDictionary *newdict=[jsonDict valueForKey:#"rows"];
NSArray *elementsArr=[newdict valueForKey:#"elements"];
NSArray *arr=[elementsArr objectAtIndex:0];
NSDictionary *dict=[arr objectAtIndex:0];
NSMutableDictionary *distanceDict=[dict valueForKey:#"distance"];
NSLog(#"distance:%#",[distanceDict valueForKey:#"text"]);
NSString *result = [[NSString alloc] initWithData:data encoding:NSASCIIStringEncoding];
address.text = [distanceDict valueForKey:#"text"];
