locationManager 'didExitRegion' not getting called iBeacon Xcode

I'm working with my iBeacon iOS app. I started coding with Xcode 5.1. Ath that time every delegates get called. But while I updated my Xcode to 6.0.1 to support the app in iOS 8, the following delegate method is not getting called (tested in device):

-(void) locationManager:(CLLocationManager*)manager 
          didExitRegion:(CLRegion*)region

It is workinng perfectly in iOS 7. Can anyone please suggest me any possible solution for me? Thanks in advance.

Solution

Kepp this with your locationmanager instance

  self.locationManager = [[CLLocationManager alloc] init];
    // New iOS 8 request for Always Authorization, required for iBeacons to work!
    if([self.locationManager respondsToSelector:@selector(requestAlwaysAuthorization)]) {
        [self.locationManager requestAlwaysAuthorization];
    }

and keep your app background refreshing ON. I am running this in iOS 8 and it is working like a charm.
