Use the following method to find Coordinates of a location from city name:

Source:(http://sickprogrammersarea.blogspot.in/2014/03/programmatically-find-co-ordinates-of.html)

-(CLLocationCoordinate2D) getLocationFromAddressString: (NSString*) addressStr {
double latitude = 0, longitude = 0;
NSString *esc_addr =  [addressStr stringByAddingPercentEscapesUsingEncoding:NSUTF8StringEncoding];
NSString *req = [NSString stringWithFormat:@"http://maps.google.com/maps/api/geocode/json?sensor=false&address=%@", esc_addr];
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];
        }
    }
}
CLLocationCoordinate2D center;
center.latitude=latitude;
center.longitude = longitude;
NSLog(@"View Controller get Location Logitute : %f",center.latitude);
NSLog(@"View Controller get Location Latitute : %f",center.longitude);
return center;

}

Hope it will be Helpful.
