Запутался, почему мой AppDelegate CLLocationManager иногда не может успешно определить CLRegionState (CLRegionState.unknown), хотя я стараюсь не вызывать requestStateForRegion
до тех пор, пока didStartMonitoringForRegion
.Похоже на какое-то состояние гонки, с которым я не понимаю, как я не справляюсь.
В связи с этим, что я должен делать, когда получаю CLRegionState.unknown?Продолжать запрашивать состояние, пока я не получу что-нибудь?(это кажется плохим)
AppDelegate:
- (BOOL)application:(UIApplication*)application didFinishLaunchingWithOptions:(NSDictionary*)launchOptions
{
self.locationManager = [[CLLocationManager alloc] init];
[self.locationManager setDelegate:self];
return [super application:application didFinishLaunchingWithOptions:launchOptions];
}
- (void)locationManager:(CLLocationManager *)manager didStartMonitoringForRegion:(nonnull CLRegion *)region {
NSLog(@"%@", [NSString stringWithFormat:@"didStartMonitoringFor region with ID: %@", region.identifier]);
// delay per https://stackoverflow.com/a/33288103/3380970
double delayInSeconds = 2.0;
dispatch_time_t popTime = dispatch_time(DISPATCH_TIME_NOW, (int64_t)(delayInSeconds * NSEC_PER_SEC));
dispatch_after(popTime, dispatch_get_main_queue(), ^(void) {
[self.locationManager requestStateForRegion:region];
});
}
- (void)locationManager:(CLLocationManager *)manager didDetermineState:(CLRegionState)state forRegion:(nonnull CLRegion *)region {
NSLog(@"%@", [NSString stringWithFormat:@"didDetermineState from AppDelegate CLLocationManager: %@ (%ld)", region.identifier, (long)state ]);
NSString *baseUrl = [self fetchBaseUrl];
switch (state) {
case CLRegionStateInside:
NSLog(@"%@", @"Determined .inside state for geofence");
[HelperFunctions postGeofenceTransitionWithBaseUrl:baseUrl region:region transitionType:1];
break;
default:
break;
}
}
