CLLocationManager didUpdateToLocation, bring values to a NSString to use elsewhere!

Using NSLog(@"%@",longi) outside this function crashes my application.... How can I use this NSLog outside the didUpdateToLocation function? Like in a IBAction function.

This example works great! But How to use this NSLogs outside this one?

- (void)locationManager:(CLLocationManager *)manager didUpdateToLocation:(CLLocation *)newLocation fromLocation:(CLLocation *)oldLocation {


    longi = [[NSString alloc] initWithFormat:@"%g", newLocation.coordinate.longitude];
    lati = [[NSString alloc开发者_JS百科] initWithFormat:@"%g", newLocation.coordinate.latitude];


    NSLog(@"%@",longi);
    NSLog(@"%@",lati);



}

You can store this values in NSUserDefaults and access them whenever needed.
