How can I get the distance in meters between two CLLocation s? CLLocation doesn't provide any method to do it, it seeems. CLLocationDistance distance = [aCLLocationA distanceFromLocation:aCLLocationB]; // distance is a double representing the distance in meters CLLocationDistance distance = [secondLocation distanceFromLocation:firstLocation]; // distance is expressed in meters CLLocationDistance kilometers = distance / 1000.0; // or you can also use this.. CLLocationDistance meters = distance; NSString *distanceString = [[NSString alloc] initWithFormat: @"%f", kilometers]; flot

I am trying to use the distanceFromLocation: method to calculate the total distance that I am walking with my iPhone in my hand. So far, I have been searching all over to help remedy my confusing, inaccurate, and seemingly arbitrary results. In these code snippets, theLabel is just a label object that is present in my app's interface, distanceMoved is the variable that I am trying to store the total distance I walked in, and locMan is a location manager that is declared in my @interface file. - (void)viewDidLoad { locMan = [[CLLocationManager alloc] init]; locMan.delegate = self; [locMan

CLLocationManager on iPhone Simulator is supposed to fake Cupertino (isn't it?) but it does NOT, it fails with kCLErrorDomain Code=0 instead. LocationManager's delegate receives the message didFailWithError . This method is implemented to log the error and the console outputs the following: Error Domain=kCLErrorDomain Code=0 "The operation couldn’t be completed. (kCLErrorDomain error 0.)" I was working on a real project when I ran into this problem but it is pointless to discuss my code because I downloaded "Locations" sample code (updated 2010-06-22 for iOS 4) from the dev center and the

I'm relatively new to Objective-C and really don't know much about it yet, so I apologise for what is probably a really amateurish question. I'm trying to get the magnetic heading from CLHeading and CLLocationDirection. However I'm getting compile errors for this line of code: locationLabel.text = [[[location course] magneticHeading] stringValue]; The errors are: warning: invalid receiver type 'CLLocationDirection' error: cannot convert to a pointer type I don't really understand what I'm doing wrong here. Please help! Here are the steps needed to use the compass. 1) check the availability: if

What I'm trying to do is pass a CLLocation to the function getPlacemarkFromLocation which then uses the passed CLLocation through reverseGeocodeLocation to set the CLPlacemark? that will be returned. I'm having issues creating the completionHandler closure in reverseGeocodeLocation , it's throwing a compiler error/crash: In Swift, CLGeocodeCompletionHandler is CLGeocodeCompletionHandler = (AnyObject[]!, NSError!) -> Void according to the documentation AnyObject[]! is supposed to contain CLPlacemark objects just like the Objective-C version. Here's my current code: class func

I need to check if user location belongs to the MKCoordinateRegion. I was surprised not to find simple function for this, something like: CGRectContainsCGPoint(rect, point) . I found following piece of code: CLLocationCoordinate2D topLeftCoordinate = CLLocationCoordinate2DMake(region.center.latitude + (region.span.latitudeDelta/2.0), region.center.longitude - (region.span.longitudeDelta/2.0)); CLLocationCoordinate2D bottomRightCoordinate = CLLocationCoordinate2DMake(region.center.latitude - (region.span.latitudeDelta/2.0), region.center.longitude + (region.span.longitudeDelta/2.0)); if

I want to make it so that it will show the amount of distance between two CLLocation coordinates. Is there someway to do this without a complex math formula? If there isn't how would you do it with a formula? Glenn Howes CLLocation has a distanceFromLocation method so given two CLLocations: CLLocationDistance distanceInMeters = [location1 distanceFromLocation:location2]; or in Swift 4: //: Playground - noun: a place where people can play import CoreLocation let coordinate₀ = CLLocation(latitude: 5.0, longitude: 5.0) let coordinate₁ = CLLocation(latitude: 5.0, longitude: 3.0) let
