Question

In my app i am showing some place on map view using MKMapView . It was showing map fine. But from yesterday it is showing only grid and not showing the map , when i add delegate method it goes in the mapviewdidfiailtoload sometime.
I am using the below code
//mapview
myMapView=[[MKMapView alloc] initWithFrame:CGRectMake(0,gameNameLabel.frame.size.height, 320, 181)];
myMapView.mapType=MKMapTypeStandard;
myMapView.delegate=self;
LocationModel *loc=presentGame.location;
NSArray *cordinates=[loc.geoCordinates componentsSeparatedByString:#","];
CLLocationCoordinate2D zoomLocation;
zoomLocation.latitude = [[cordinates objectAtIndex:0] doubleValue];
zoomLocation.longitude= [[cordinates objectAtIndex:1] doubleValue];
MKCoordinateRegion viewRegion = MKCoordinateRegionMakeWithDistance(zoomLocation, 0.5*METERS_PER_MILE, 0.5*METERS_PER_MILE);
// 3
MKCoordinateRegion adjustedRegion = [myMapView regionThatFits:viewRegion];
// 4
[myMapView setRegion:adjustedRegion animated:YES]; [scroll addSubview:myMapView];
Place *pin = [[Place alloc] init];
pin.name = loc.gameLocation;
pin.latitude = [[cordinates objectAtIndex:0] doubleValue];
pin.longitude = [[cordinates objectAtIndex:1] doubleValue];
PlaceMark* Place1 = [[PlaceMark alloc] initWithPlace:pin];
Place1.tagg=1;
[myMapView addAnnotation:Place1];
//end of mapview
- (MKAnnotationView *)mapView:(MKMapView *)mapView1 viewForAnnotation:(id )annotation {
static NSString *identifier = #"PlaceMark";
if ([annotation isKindOfClass:[PlaceMark class]]) {
MKPinAnnotationView *annotationView = (MKPinAnnotationView *) [mapView1 dequeueReusableAnnotationViewWithIdentifier:identifier];
annotationView.tag=[mapView1.annotations count];
if (annotationView == nil) {
annotationView = [[MKPinAnnotationView alloc] initWithAnnotation:annotation reuseIdentifier:identifier];
} else {
annotationView.annotation = annotation;
}
annotationView.enabled = YES;
annotationView.canShowCallout = YES;
return annotationView;
}
return nil;
}
METERS_PER_MILE is defined as 1609.344
and i have set delegate in .h file .
All thing was working fine but now it showing the grid only , it showing Pin atleaset

Answer 1

I had the same problem MKMap View showing Only Grid not Showing Map View. I found out it was related to a change I made to the time/date on my mac. When I fixed the time and date to current time, the map worked again.

The iOS simulator comes with the official maps app included. Open that and verify that it can get tiles, it could be a network issue. If the Maps app isn't showing any tiles then you have network issues.
Can you try by turning off the animation by changing the line
[myMapView setRegion:adjustedRegion animated:YES];
By
[myMapView setRegion:adjustedRegion animated:NO];
