core-location

I am new to iPhone programming. I am looking for an example or a demo on how to use startMonitoringSignificantLocationChanges method with the CoreLocation Manager. I am confused by the documentation because, I am not sure if the same delegate method is called as in the case of invoking startUpdatingLocation . (i.e. the delegate locationManager: (CLLocationManager *)manager didUpdateToLocation: (CLLocation *)newLocation fromLocation: (CLLocation *)oldLocation is called) Any help on this would be appreciated. Also, I am testing it on the simulator by subclassing of CLLocationManager . This

I understand the difference between monitoring and ranging, and I understand the limitation of iOS in that beacon ranging can only happen in the foreground or in the background when entering and exiting regions as explained here ( http://developer.radiusnetworks.com/2013/11/13/ibeacon-monitoring-in-the-background-and-foreground.html ). But I'm trying to figure out how to solve a common scenario. If I had a bunch of beacons installed in a department store, how am I supposed to detect when a person moves within range of those beacons? With the way it currently works, the app will get an event

I'm looking for an open source app or library to track user location in the background. Now I'm trying to do it with CLLocation and background tasks, but accuracy is not enough for my case. Could you explain, how apps, like "moves", "runkeeper", "endmondo", creates my route? Should I use Accelerometer or/and compass to create a route between CLLocation background points? Some code: //location manager init self.locationManager = [[CLLocationManager alloc] init]; self.locationManager.distanceFilter = kCLDistanceFilterNone; self.locationManager.desiredAccuracy = kCLLocationAccuracyBest; self

I need to implement a native iPhone app to measure the velocity of the phone (basically a speedometer). I know that you can do so via the CoreLocation API fairly easily, but I am concerned about battery consumption since this is to be a real-time measurement that could be used for up to a couple of hours at a time. My understanding is that while you are actively monitoring for events from the LocationManager (even though I don't actually care about GPS location) it is battery-intensive. The other obvious option to explore would be using the accelerometers to try and calculate speed, but there

My project worked perfectly on simulator+device, but now, after upgrading to lion os and xcode 4.1 , I get this error when gps is active! server did not accept client registration 68 It's a gps based application, and i'm nervous to not debug app in simulator! Any idea to solve this issue? UPDATE : Gps on Simulator doesn't work also on Xcode 3.2.6 + LION. EDIT : Apple response on bug tracker: After further investigation it has been determined that this is a known issue, which is currently being investigated by engineering. This issue has been filed in our bug database under the original Bug ID#
