Answer 1

From the Big Nerd Ranch forum:

@implementation CLLocationManager (TemporaryHack)
- (void)hackLocationFix {
    CLLocation *location = [[CLLocation alloc] initWithLatitude:42 longitude:-50];
    [[self delegate] locationManager:self didUpdateToLocation:location fromLocation:nil];     
}
- (void)hackHeadingFix {
    [[self delegate] locationManager:self didUpdateHeading:(id)@"That way.."];
}
- (void)startUpdatingLocation {
    [self performSelector:@selector(hackLocationFix) withObject:nil afterDelay:0.1];
}
- (void)startUpdatingHeading {
    [self performSelector:@selector(hackHeadingFix) withObject:nil afterDelay:0.1];
}
