Hello Friends,

In order to fetch the latitude and longitude of a location based on its address,you may use the following code:
 

double latitude = 0;

double longitude = 0;

Use the google api along with your address

 NSString *req = [NSString stringWithFormat:@"http://maps.google.com/maps/api/geocode/json?sensor=false&address=%@", @"Your address "];

Connect to the api and the result is stored here in result variable
 

NSString *result = [NSString stringWithContentsOfURL:[NSURL URLWithString:req] encoding:NSUTF8StringEncoding error:NULL];
    if (result) {
        NSScanner *scanner = [NSScanner scannerWithString:result];
        if ([scanner scanUpToString:@"\"lat\" :" intoString:nil] && [scanner scanString:@"\"lat\" :" intoString:nil]) {
            [scanner scanDouble:&latitude];
            if ([scanner scanUpToString:@"\"lng\" :" intoString:nil] && [scanner scanString:@"\"lng\" :" intoString:nil]) {
                [scanner scanDouble:&longitude];
            }
        }
    }

Creating location coordinate on the basis of the fetched latitude and longitude

 CLLocationCoordinate2D center;
    center.latitude=latitude;
    center.longitude = longitude;
