Geofencing didEnterRegion, didExitRegion function not call in iphone 5S iOS8.1

Question

I debugged all day, and the delegate was generally called.

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

Well here is my standard code calling the monitor. use CoreLocation.framework.

[locationManager startMonitoringForRegion:geofence];

And registered them in my plist.

<key>NSLocationAlwaysUsageDescription</key>
<string>Lugang</string>
<key>NSLocationWhenInUseUsageDescription</key>
<string>Lugang</string>

Updating the background application in resolution, but I did not see my application inside.

I tried to print my controlled Regions in the LocationManager example, and there is my controlled area.

NSLog(@"%@" ,locationManager.monitoredRegions);

and regionMonitoringAvailable is true.

NSLog(@"%d" , [CLLocationManager regionMonitoringAvailable] );

In iOS 8, I asked for requestAlwaysAuthorization

[locationManager requestAlwaysAuthorization];

I tried three states, the application is in the foreground, the application is in the background, the application is inactive. none of these conditions were caused.

-(void)locationManager:(CLLocationManager *)manager didFailWithError:(NSError *)error

there were no errors.

And I tried

[locationManager requestStateForRegion:geofence];

works great.

- (void)locationManager:(CLLocationManager *)manager didDetermineState:(CLRegionState)state forRegion:(CLRegion *)region

activated in my requestStateForRegion.

   {
       [locationManagerGeofence stopMonitoringForRegion:monitored];
   }
   self.geofencesArray = [NSMutableArray arrayWithArray:[self buildGeofenceData]];
   if([CLLocationManager regionMonitoringAvailable])
   {
       for (CLRegion *region in self.geofencesArray)
       {
           [locationManagerGeofence startMonitoringForRegion:region desiredAccuracy:kCLLocationAccuracyBest];
       }
   }
   else
   {
       [BB_Global displayAlertWithTitle:@"" message:@"This app requires region monitoring features which are unavailable on this device."];
