MKMapView tiles not loaded with zoom

Question

I've got an issue. I'm using a MKMapView for displaying some annotations. I initialize a map view with default zoom. And it displays some map.

but when i try zooming, tiles not loaded, and map becomes empty. Like this.

I create my Map View via interface builder.

@property (nonatomic, weak) IBOutlet MKMapView* mapView;

What am I doing wrong? Is there any mandatory methods for implementation, that affect on this functional? And yes, there is an internet connection on my device.

Answer 1

Generally this can happens due to internet connection. If you have slow internet connection than it takes time to load map tiles.

About methods i recommended to override below method.

Override MKMapView delegate method -

- (void)mapView:(MKMapView *)mapView regionDidChangeAnimated:(BOOL)animated

Will call every time you zoom in/out and load map tiles.

PS - provide MKMapViewDelegate to your view controller.
