iOS 7.1 map 未加载并给出以下消息

Question

这是我在尝试加载 mapView 时看到的消息。我的注释加载正常，但没有 map ，或者有时是部分 map 。我得到一个空白页。但是当我平移时，某些 map 会加载。
*edit::似乎发生在 iPod touch 7.1 - iPhone 5 工作正常

Localization tile 22.50.7 GEOTileSetStyle_VECTOR_POI, GEOTileSize_PX512, GEOTileScale_NODPI.en is not in VLOC format

我的代码:

[self.mapView setDelegate:self];
[self.mapView setShowsUserLocation:YES];
[self.mapView setMapType:MKMapTypeStandard];

// get location from search
CLLocationCoordinate2D zoomLocation;
zoomLocation.latitude = self.searchLat;
zoomLocation.longitude= self.searchLon;

MKCoordinateRegion viewRegion = MKCoordinateRegionMakeWithDistance(zoomLocation, self.mapScale*METERS_PER_MILE, self.mapScale*METERS_PER_MILE);
[self.mapView setRegion:viewRegion animated:YES];

// remove all previous annotations
for (id<MKAnnotation> annotation in self.mapView.annotations)
{
    [self.mapView removeAnnotation:annotation];
}

for (int i = 0; i < [self.mapArray count]; i++)
{
    MyInfo *info = [self.mapArray objectAtIndex:i];
    CLLocationCoordinate2D coord;
    coord.latitude = info.lat;
    coord.longitude = info.lon;

    NSInteger count = i+1;
    MyAnnotation *annotation = [[MyAnnotation alloc] initWithCoordinate:coord title:info.desc clubInfo:info index:count];
    [self.mapView addAnnotation:annotation];
}

我在 Xcode 5.0 中也有类似的错误。
将 Xcode 升级到 5.1 解决了这个问题。
