On a device running ios 5 my app works great, but on a device running ios 4.2.1 i get this crash. The strange thing is that the device crash only when NOT connected to xcode. When run from xcode it work but when i run it without xcode the app is working till the moment i call the method:
- (void)startLocationUpdates
{
self.locationManager.desiredAccuracy = kCLLocationAccuracyBestForNavigation;
self.locationManager.distanceFilter = 1;
self.locationManager.delegate = self;
[self.locationManager startUpdatingLocation];
}

Are you sure that self
is living all the time you use it and you set self.locationManager.delegate = nil;
before you destroy self
?
