displaying current distance

I'm trying to obtain the current distance that has been travelled since LocationManager was started. But i'm facing a few issues.

here is the code I have so far:

-(void)locationManager:(CLLocationManager *)manager didUpdateToLocation:(CLLocation *)newLocation fromLocation:(CLLocation *)oldLocation {
    if (self.startLocation == nil)
    {
        totalDistanceBetween = 0;
        _startLocation = newLocation;
    }
    CLLocationDistance distanceBetween = [newLocation distanceFromLocation:_startLocation ];
    self.startLocation = newLocation;
    totalDistanceBetween += distanceBetween;
    NSString *cycleDistanceString = [[NSString alloc]
                            initWithFormat:@"%f",
                            totalDistanceBetween];
    _CurrentDistance.text = cycleDistanceString;
}


@end

When I run my app my label CurrentDistance is not updated at all. I'm still relatively new to objective-c so not sure where I'm going wrong any ideas?

Thanks

You should add a log or debug to ensure you are receiving location callbacks. If not, you haven't registered for updates (properly).

If you are getting callbacks then I guess _CurrentDistance is an outlet to a label which isn't connected (so you are asking nil to do something and nothing happens).
