地圖不加載，只顯示平鋪視圖？

Question

我得到以下調試信息，與地圖沒有加載在所有。

Trying to initialize GEOVectorTile (2047.2047.12 GEOTileSetStyle_VECTOR_ROADS, GEOTileSize_PX512, GEOTileScale_NODPI) with non-VMP4 data. 

Answer 1

下面是縮放到您當前位置的代碼。

mpView.showsUserLocation = YES; 

[mpView setCenterCoordinate:mpView.userLocation.location.coordinate animated:YES]; 

[mpView showAnnotations:mpView.annotations animated:YES]; 

這裏我已經創建了一個按鈕，在點擊按鈕，我可以輕鬆地瀏覽到當前位置。

-(void)btnCurrentlocationClicked:(id)sender 
{ 
    MKCoordinateRegion region = MKCoordinateRegionMakeWithDistance(ApplicationDelegate.locationManager.location.coordinate, 250, 250); 
    [mpView setRegion:region animated:YES]; 

    [mpView setCenterCoordinate:mpView.userLocation.location.coordinate animated:YES]; 

    // [mpView selectAnnotation:mapPin animated:YES]; 
    [mpView showAnnotations:mpView.annotations animated:YES]; 
} 

這裏是我的VierForAnnotation

- (MKAnnotationView *)mapView:(MKMapView *)mapview viewForAnnotation:(id <MKAnnotation>)annotation 
{ 
    NSLog(@"viewForAnnotation"); 

    if ([annotation isKindOfClass:[MKUserLocation class]]) { 
     NSLog(@"Is the user %f, %f", [annotation coordinate].latitude, [annotation coordinate].longitude); 
//  MKCoordinateRegion region = MKCoordinateRegionMakeWithDistance(ApplicationDelegate.locationManager.location.coordinate, 250, 250); 
//  [mpView setRegion:region animated:YES]; 

     return nil; 
    } 


    static NSString* AnnotationIdentifier = @"AnnotationIdentifier"; 
    MKAnnotationView *annotationView = [mpView dequeueReusableAnnotationViewWithIdentifier:AnnotationIdentifier]; 

    NSString *strAnnotationSubtitle = [(MKPointAnnotation *)annotation subtitle]; 

    if (annotationView == nil) 
    { 
     annotationView = [[MKAnnotationView alloc] initWithAnnotation:annotation reuseIdentifier: AnnotationIdentifier] ; 
    } 
    else 
    { 
     annotationView.annotation = annotation; 
    } 
    annotationView.draggable=YES; 
    annotationView.canShowCallout = YES; 

    if([strAnnotationSubtitle isEqualToString:@"Pickup"]) 
    { 
     annotationView.image = [UIImage imageNamed:@"ic_pin_pickup"]; 
    } 
    else if ([strAnnotationSubtitle isEqualToString:@"Drop"]) 
    { 
     annotationView.image = [UIImage imageNamed:@"ic_pin_drop"]; 
    } 
    return annotationView; 
}
