快速在googlemaps图层上方添加图层 [英] Add layer above googlemaps layer in swift

问题描述

我尝试通过Google地图文档中的代码在Google地图上添加自己的图层:

I tried to add my own layer on google maps by code from google maps documentation:

extension MapViewController {
func addTiles() {
    // Implement GMSTileURLConstructor
    // Returns a Tile based on the x,y,zoom coordinates, and the requested floor
    let urls = { (x: UInt, y: UInt, zoom: UInt) -> NSURL in
        let url = "http://example.pl/ras/\(zoom)/\(x),\(y).v\(1).png";

        return NSURL(string: url)!
    }

    // Create the GMSTileLayer
    let layer = GMSURLTileLayer(URLConstructor: urls)
    layer.tileSize = 512
    layer.map = mapView
}}

我有这样的东西:

我没有看到应该在我的瓷砖下面的地形.我的瓷砖是透明的.您知道什么地方可能出问题吗?

I don't see terrain which should be under my tile. My tiles are transparent. Do you have any idea what can be wrong?
