Question

我试图使用MapBox的MBXMapKit为我的地图添加自定义样式。我已经关注了示例应用和文档，但我一直看到标准的MapKit用户界面。

我在这里错过了一些明显的东西吗？我已经从SampleApp @ MBXMapBox GitHub添加了协议方法，并添加了MBXRasterTileOverlay，因为我应该......所以我不确定缺少什么。

    [self setUpNavigationBarView];

    MBXRasterTileOverlay *blah = [[MBXRasterTileOverlay alloc] initWithMapID:@"sparkyrobinson.jp6f81f2" includeMetadata:YES includeMarkers:YES];

    MBXRasterTileOverlay *rasterOverlay = [[MBXRasterTileOverlay alloc] initWithMapID:@"sparkyrobinson.jp6f81f2"];
    rasterOverlay.delegate = self;
    [self.mapView addOverlay:blah];

干杯。

一切看起来都不错。您确定self.mapView插座已连接，并且您没有向nil添加叠加层吗？

MBXMapKit叠加不起作用
