If we run the LocationManager in the background, running all the time without a break.This method is especially demanding on the battery, and do not always need to detect location continuously.Often we need to know the location of the specified interval.iOS has several options how to correctly run the application in the background.These methods are enabled with iOS.We’ll use the one that your application will use and which we need.All services we can see in UIBackgroundModes array: Service you want to use must allow the application.This we do in Info.plist and add value with key “Required backgdound modes“.We do it as follows: If we have included location service in background mode (set in info.plist), we can try run this service after switch application into background.We will use the methods in the AppDelegate, which allows to recognize that the application was switched to background: We can write a simple example that will run locationManager only if the application is in the background: @interface AppDelegate : UIResponder { CLLocationManager *locationManager; UIApplication *app; } //other properties 123456 { ; ;} //implementation AppDelegate @implementation AppDelegate //run when app is almost ready to run.

My final procedure is use NSTimer in the background by using UIApplication:beginBackgroundTaskWithExpirationHandler:.This timer triggers periodically while the application runs in the background.You can view the following example: #import "AppDelegate.h" @implementation AppDelegate BOOL locationStarted = FALSE; - (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions { //set default value after application starts locationStarted = FALSE; //create CLLocationManager variable locationManager = [[CLLocationManager alloc] init]; //set delegate locationManager.delegate = self; app = [UIApplication sharedApplication]; return YES; } //update location -(void)locationManager:(CLLocationManager *)manager didUpdateToLocation:(CLLocation *)newLocation fromLocation:(CLLocation *)oldLocation{ NSLog(@"Location: %f, %f", newLocation.coordinates.longtitude, newLocation.coordinates.latitude); } //run background task -(voud)runBackgroundTask: (int) time{ //check if application is in background mode if ([UIApplication sharedApplication].applicationState == UIApplicationStateBackground) { //create UIBackgroundTaskIdentifier and create tackground task, which starts after time __block UIBackgroundTaskIdentifier bgTask = [app beginBackgroundTaskWithExpirationHandler:^{ [app endBackgroundTask:bgTask]; bgTask = UIBackgroundTaskInvalid; }]; dispatch_async(dispatch_get_global_queue(DISPATCH_QUEUE_PRIORITY_HIGH, 0), ^{ NSTimer* t = [NSTimer scheduledTimerWithTimeInterval:time target:self selector:@selector(startTrackingBg) userInfo:nil repeats:NO]; [[NSRunLoop currentRunLoop] addTimer:t forMode:NSDefaultRunLoopMode]; [[NSRunLoop currentRunLoop] run]; }); } } //starts when application switchs into backghround - (void)applicationDidEnterBackground:(UIApplication *)application { //check if application status is in background if ( [UIApplication sharedApplication].applicationState == UIApplicationStateBackground) { NSLog(@"start backgroun tracking from appdelegate"); //start updating location with location manager [locationManager startUpdatingLocation]; } //change locationManager status after time [self runBackgroundTask:20]; } //starts with background task -(void)startTrackingBg{ //write background time remaining NSLog(@"backgroundTimeRemaining: %.0f", [[UIApplication sharedApplication] backgroundTimeRemaining]); //set default time int time = 60; //if locationManager is ON if (locationStarted == TRUE ) { //stop update location [locationManager stopUpdatingLocation]; locationStarted = FALSE; }else{ //start updating location [locationManager startUpdatingLocation]; locationStarted = TRUE; //ime how long the application will update your location time = 5; } [self runBackgroundTask:time]; } //application switchs back from background - (void)applicationWillEnterForeground:(UIApplication *)application { locationStarted = FALSE; //stop updating [locationManager stopUpdatingLocation]; } /*** other methods ***/ - (void)applicationWillResignActive:(UIApplication *)application{} - (void)applicationDidBecomeActive:(UIApplication *)application{} - (void)applicationWillTerminate:(UIApplication *)application{} @end 123456789 = ;- ():( *):( *){ = ; = [[ ]];.vaporizer store australia
