关于临时禁止后CLLocationManager不返回位置

设置CLLocationManager代理：

CLLocationManager *locationManager = [ [CLLocationManager alloc] init];
locationManager.delegate = self;
[locationManager startUpdatingLocation];

然后试试CLLocationManager的代理：

- (void)locationManager:(CLLocationManager *)manager didUpdateToLocation:(CLLocation *)newLocation fromLocation:(CLLocation *)oldLocation
{
    self.currentLocation = newLocation;            
}
- (void)locationManager:(CLLocationManager *)manager didFailWithError:(NSError *)error {
    // The location "unknown" error simply means the manager is currently unable to get the location.
    // We can ignore this error for the scenario of getting a single location fix, because we already have a
    // timeout that will stop the location manager to save power.
    if ([error code] != kCLErrorLocationUnknown) {
        [self stopUpdatingLocation:NSLocalizedString(@"Error", @"Error")];
    }
}
