I am trying to receive heading (direction in which phone is pointed) for iPhone.
I am trying the code below,
- (void)startHeadingEvents {
if (!self.locManager) {
CLLocationManager* theManager = [[[CLLocationManager alloc] init] autorelease];
// Retain the object in a property.
self.locManager = theManager;
locManager.delegate = self;
}
// Start location services to get the true heading.
locManager.distanceFilter = 1000;
locManager.desiredAccuracy = kCLLocationAccuracyKilometer;
[locManager startUpdatingLocation];
// Start heading updates.
if ([CLLocationManager headingAvailable]) {
locManager.headingFilter = 5;
[locManager startUpdatingHeading];
}
}
- (void)locationManager:(CLLocationManager *)manager didUpdateHeading:(CLHeading *)newHeading {
if (newHeading.headingAccuracy < 0)
return;
// Use the true heading if it is valid.
CLLocationDirection theHeading = ((newHeading.trueHeading > 0) ?
newHeading.trueHeading : newHeading.magneticHeading);
self.currentHeading = theHeading;
[self updateHeadingDisplays];
}
Its similar to Apple's iOS developer library and programming guide. The code always returns heading degree between 0 to 10 or 355 to 359. I don't get the values in between.
More, I get this problem only on iPhone 6S and iPhone 6S plus. Otherwise this is perfectly working on iPhone 4S, 5, 5S, 6, 6 Plus. And my all phones are using the latest iOS.
I tried to google it out, but not finding any help or solution. Can anyone please advice me here if something is wrong or needs to be changed?
Thanks.
