ios - 在 Objective C 中显示 MapKit "Map loading error"

Question

我正在使用 Mapkit 和 objective-c ，我想在 map 上显示“错误警报”。 当 Internet 工作时，它工作正常，但当 Internet 工作不正常时，它会自动在日志上显示“请求超时”，而无需调用“ma​​pViewDidFailLoadingMap”委托(delegate)方法。

代码在这里:

- (void)viewDidLoad 
{
    [super viewDidLoad];
    // Do any additional setup after loading the view.

    mapView.delegate=self;
    mapView.showsUserLocation = YES;
    [mapView setMapType:MKMapTypeStandard];
    [mapView setZoomEnabled:YES];
    [mapView setScrollEnabled:YES];

    //[self activeCLLocation];
}

-(void)mapView:(MKMapView *)mapView didUpdateUserLocation:(MKUserLocation *)userLocation
{
    NSLog(@"user latitude==>%f",userLocation.location.coordinate.latitude);
    NSLog(@"user longitude==>%f",userLocation.location.coordinate.longitude);
}


-(void)mapViewDidFailLoadingMap:(MKMapView *)mapView withError:(NSError *)error
{
    NSLog(@"error map===>%@",error.description);
}

-(void)mapView:(MKMapView *)mapView didFailToLocateUserWithError:(NSError *)error
{
    NSLog(@"error loc===>%@",error.description);
}

显示错误:

2015-05-27 12:51:57.624 EventLocator[1262:160081] Could not determine current country code: Error Domain=NSURLErrorDomain Code=-1001 "The request timed out."

我会在您加载 mapKit 之前测试有效的互联网连接。查看此线程以了解如何执行此操作。
