如何＆＃34;关闭＆＃34;没有位置管理器的地图视图消失时的位置服务？

Question

我在视图控制器中有MKMapView我打电话：

[self.mapView setUserTrackingMode:MKUserTrackingModeFollow animated:YES];

当我导航到另一个视图控制器并且地图视图的控制器消失时，我仍然运行位置服务（我在状态栏中看到箭头）。一旦我没有看到地图，我想把它关掉，但我不知道如何在没有CLLocationManager的情况下做到这一点...

Answer 1

-(void)viewWillAppear:(BOOL)animated {
    [super viewWillAppear:animated];

if ([CLLocationManager significantLocationChangeMonitoringAvailable])
    {
        if (OUTPUT_LOGS) NSLog(@"Stopped monitoring for significant changes");
        [[self locationManager] stopMonitoringSignificantLocationChanges];
    }

    [[self locationManager] startUpdatingLocation];

}


-(void)viewWillDisappear:(BOOL)animated {

    [super viewWillDisappear:animated];

    if ([CLLocationManager significantLocationChangeMonitoringAvailable])
            {
                [self.locationManager startMonitoringSignificantLocationChanges];


            }

 [[self locationManager] stopUpdatingLocation];
}

Answer 2

这似乎有效：

- (void)viewDidDisappear:(BOOL)animated
{
   [super viewDidDisappear:animated];

   self.mapView.showsUserLocation = NO;
   [self.mapView setUserTrackingMode:MKUserTrackingModeNone animated:YES];
}
