//parse out the json data
NSString *data1 = [NSString stringWithUTF8String:[responseData bytes]];
NSLog(#"Response data: %#", data1);
NSError* error;
NSDictionary* json = [NSJSONSerialization JSONObjectWithData:responseData options:kNilOptions error:&error];
//The results from Google will be an array obtained from the NSDictionary object with the key "results".
NSArray* responseResults = [json objectForKey:#"results"];
NSLog(#"Locations are %#", responseResults);
}
- (void)didReceiveMemoryWarning
{
[super didReceiveMemoryWarning];
// Dispose of any resources that can be recreated.
}
#end
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
now in "NSLog(#"Locations are %#", responseResults);" i am getting my values, i simply want to add these values onto the map in the form of pointers with details.
So kindly help me how it should be done. (And kindly help me with the help of codes)

Answer 1

you can do this by using MKPointAnnotation and then add this MKPointAnnotation in you mapview
CLLocationCoordinate2D annotationCoord;
annotationCoord.latitude = #"your Latitude to point on map";
annotationCoord.longitude = #"your Longitude to point on map";;
MKPointAnnotation *annotationPoint = [[MKPointAnnotation alloc] init];
annotationPoint.coordinate = annotationCoord;
annotationPoint.title = #"your title";
annotationPoint.subtitle = #"your subtitle";
[YourmapView addAnnotation:annotationPoint];
