在Geo-Fencing中多次调用区域监控方法

我创build了多个地理围栏来监视区域进入/退出事件。

我在AppDelegate.h文件中创build了一个位置pipe理器 。

 @interface AppDelegate : UIResponder <UIApplicationDelegate, CLLocationManagerDelegate> @property (strong, nonatomic) UIWindow *window; @property(nonatomic,retain)CLLocationManager *locationManager; @property(nonatomic,retain)CLLocation *currentLocation; +(AppDelegate *)sharedDelegate; 

AppDelegate.m文件

 - (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions { UILocalNotification *notification = [launchOptions objectForKey:UIApplicationLaunchOptionsLocalNotificationKey]; if (notification) { NSLog(@"AppDelegate didFinishLaunchingWithOptions"); application.applicationIconBadgeNumber = 0; } if ([application respondsToSelector:@selector(registerUserNotificationSettings:)]) { UIUserNotificationSettings *settings = [UIUserNotificationSettings settingsForTypes:(UIUserNotificationTypeBadge|UIUserNotificationTypeAlert|UIUserNotificationTypeSound) categories:nil]; [application registerUserNotificationSettings:settings]; } else // iOS 7 or earlier { UIRemoteNotificationType myTypes = UIRemoteNotificationTypeBadge | UIRemoteNotificationTypeAlert | UIRemoteNotificationTypeSound; [application registerForRemoteNotificationTypes:myTypes]; } if (!self.locationManager) { self.locationManager = [[CLLocationManager alloc] init]; } self.locationManager.delegate = self; //locationManager.distanceFilter = kCLDistanceFilterNone; self.locationManager.desiredAccuracy = kCLLocationAccuracyBestForNavigation; self.locationManager.distanceFilter = 2.0f; self.locationManager.activityType = CLActivityTypeAutomotiveNavigation; if ([[[UIDevice currentDevice] systemVersion] floatValue] >= 8.0) { [self.locationManager requestAlwaysAuthorization]; } if ([self.locationManager respondsToSelector:@selector(allowsBackgroundLocationUpdates)]) { self.locationManager.allowsBackgroundLocationUpdates = YES; } if ([self.locationManager respondsToSelector:@selector(pausesLocationUpdatesAutomatically)]) { self.locationManager.pausesLocationUpdatesAutomatically= NO; } [self.locationManager stopMonitoringSignificantLocationChanges]; if ([CLLocationManager locationServicesEnabled] && [CLLocationManager authorizationStatus] != kCLAuthorizationStatusDenied) { [self.locationManager startUpdatingLocation]; } // Override point for customization after application launch. return YES; } -(void)locationManager:(CLLocationManager *)manager didStartMonitoringForRegion:(CLRegion *)region { NSLog(@"Started monitoring %@ region",region.identifier); } -(void)locationManager:(CLLocationManager *)manager didUpdateLocations:(NSArray<CLLocation *> *)locations { NSLog(@"%@",[locations description]); } -(void)locationManager:(CLLocationManager *)manager didEnterRegion:(CLRegion *)region { dispatch_async(dispatch_get_main_queue(), ^{ if ([[UIApplication sharedApplication] applicationState]==UIApplicationStateBackground || [[UIApplication sharedApplication] applicationState]==UIApplicationStateInactive) { UILocalNotification *localnotification = [[UILocalNotification alloc]init]; localnotification.fireDate=[NSDate dateWithTimeIntervalSinceNow:1]; localnotification.alertBody=@"You are enter in region."; localnotification.timeZone=[NSTimeZone defaultTimeZone]; localnotification.repeatInterval = 0; localnotification.hasAction=YES; [[UIApplication sharedApplication]scheduleLocalNotification:localnotification]; } else { [[[UIAlertView alloc]initWithTitle:@"message" message:@"Enter into region." delegate:self cancelButtonTitle:nil otherButtonTitles:@"Ok ", nil] show]; } }); } -(void)locationManager:(CLLocationManager *)manager didExitRegion:(CLRegion *)region { dispatch_async(dispatch_get_main_queue(), ^{ if ([[UIApplication sharedApplication] applicationState]==UIApplicationStateBackground || [[UIApplication sharedApplication] applicationState]==UIApplicationStateInactive) { UILocalNotification *localnotificationExit = [[UILocalNotification alloc]init]; localnotificationExit.fireDate=[NSDate dateWithTimeIntervalSinceNow:1]; localnotificationExit.alertBody=@"You are exit from region."; NSLog(@"Exit from region."); localnotificationExit.timeZone=[NSTimeZone defaultTimeZone]; localnotificationExit.repeatInterval = 0; localnotificationExit.hasAction=YES; [[UIApplication sharedApplication]scheduleLocalNotification:localnotificationExit]; } else { [[[UIAlertView alloc]initWithTitle:@"message" message:@"Exit from region." delegate:self cancelButtonTitle:nil otherButtonTitles:@"Ok ", nil] show]; } }); } - (void)locationManager:(CLLocationManager *)manager didFailWithError:(NSError *)error { NSLog(@"didFailWithError: %@", error); [[[UIAlertView alloc] initWithTitle:@"Error" message:@"Failed to Get Your Location" delegate:nil cancelButtonTitle:@"OK" otherButtonTitles:nil] show]; } 

这是pipe理区域监控的事情。

现在我的视图控制器正在添加监视区域。

 -(void)AddRegionsInGeoFence { NSUserDefaults *standardDefaults = [NSUserDefaults standardUserDefaults]; //----1 CLLocationCoordinate2D centerCoordinate1 = CLLocationCoordinate2DMake(23.046518, 72.543337); CLCircularRegion *region1 =[[CLCircularRegion alloc] initWithCenter:centerCoordinate1 radius:200 identifier:@"Location First"]; NSLog(@"%@",[region1 description]); region1.notifyOnEntry=YES; region1.notifyOnExit=YES; if (![standardDefaults boolForKey:@"EnterRegion"]) { [[AppDelegate sharedDelegate].locationManager startMonitoringForRegion:region1]; NSLog(@"Started Monitoring- %@", [region1 description]); } [self.mapview setShowsUserLocation:YES]; [self.mapview setUserTrackingMode:MKUserTrackingModeFollow animated:YES]; //----2 CLLocationCoordinate2D centercoordinate2=CLLocationCoordinate2DMake(23.064381, 72.531181); CLCircularRegion *region2=[[CLCircularRegion alloc]initWithCenter:centercoordinate2 radius:200 identifier:@"Location Second"]; NSLog(@"%@",[region2 description]); region2.notifyOnEntry=YES; region2.notifyOnExit=YES; if (![standardDefaults boolForKey:@"EnterRegion"]) { [[AppDelegate sharedDelegate].locationManager startMonitoringForRegion:region2]; NSLog(@"Started Monitoring- %@", [region2 description]); } //----3 CLLocationCoordinate2D centercoordinate3=CLLocationCoordinate2DMake(23.083583,72.546441); CLCircularRegion *region3=[[CLCircularRegion alloc]initWithCenter:centercoordinate3 radius:200 identifier:@"Location Third"]; NSLog(@"%@",[region3 description]); region3.notifyOnEntry=YES; region3.notifyOnExit=YES; if (![standardDefaults boolForKey:@"EnterRegion"]) { [[AppDelegate sharedDelegate].locationManager startMonitoringForRegion:region3]; NSLog(@"Started Monitoring- %@", [region3 description]); } //4 CLLocationCoordinate2D centercoordinate4=CLLocationCoordinate2DMake(23.122255, 72.584499); CLCircularRegion *region4=[[CLCircularRegion alloc]initWithCenter:centercoordinate4 radius:500 identifier:@"Location Fourth"]; NSLog(@"%@",[region4 description]); region4.notifyOnEntry=YES; region4.notifyOnExit=YES; if (![standardDefaults boolForKey:@"EnterRegion"]) { [[AppDelegate sharedDelegate].locationManager startMonitoringForRegion:region4]; NSLog(@"Started Monitoring- %@", [region4 description]); [standardDefaults setBool:YES forKey:@"EnterRegion"]; [standardDefaults synchronize]; } } 

我的问题是区域监控方法被称为多次，即使我不移动区域本身。 其他一切工作正常， 准确缓冲区大约50-80 meters ，这对我来说很好。

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

另外，如果我正在closuresWi-Fi，那么它会调用这些方法来回退出区域并进入区域。 据我所知，GPS的准确性取决于Wi-Fi。

任何帮助将不胜感激。
