使用以下开源 Route Me 应用程序我正在加载 Maptiles
mapview = [[RMMapView alloc] initWithFrame:CGRectMake(0.0f, 0.0f, 320.0f, 460.0f)];
[mapview setBackgroundColor:[UIColor whiteColor]];
mapview.delegate = self;
id <RMTileSource> tileSource = [[[RMDBMapSource alloc] initWithPath:"@tilefile.db"] autorelease];
RMMapContents *rmcontents = [[RMMapContents alloc] initWithView:mapview tilesource:tileSource];
[self.view addSubview:mapview];//attached to mapview
如果 RMMapContents 中有一种方法可以让我将地图 4 个角作为 CLLocationCoordinate2D 获取,那就太好了?有一个
- (RMSphericalTrapezium) latitudeLongitudeBoundingBox;
如何从上述方法中获得 4 个角的位置?
