谷歌静态地图无法在iOS设备上加载
本文关键字：加载 iOS 静态 地图 谷歌 | 更新日期: 2023-09-27 18:04:24
我正在用Unity编写一款游戏，我需要加载一个静态地图。地图在编辑器和Android设备中正确显示，但在iOS设备中不正确显示。它说网址不正确…我不知道怎么解决。有人能帮帮我吗?
我用下面的代码调用这个map:
url= "http://maps.google.com/maps/api/staticmap?center="+fixLat+","+fixLon+"&zoom="+zoom+"&scale=2&size=640x640&style=feature:all|element:geometry|hue:0x00fff0|lightness:0|gamma:0.21|visibility:on&style=feature:all|element:labels|visibility:off&style=feature:landscape.man_made|element:geometry|color:0x133f42|visibility:on&style=feature:landscape.natural|element:geometry.fill|visibility:on|hue:0x00ffd2|saturation:35|lightness:0|gamma:0.5&style=feature:poi|element:geometry.fill|lightness:0|gamma:0.6|visibility:on&style=feature:poi.park|element:geometry|visibility:on|saturation:0|color:0x2e9470&style=feature:road|element:geometry.fill|visibility:on|color:0x05111a&style=feature:road|element:geometry.stroke|visibility:off&style=feature:transit|element:geometry|visibility:off"+key;

这些是屏幕截图。编辑器和Android设备
iOS设备
运行问题中的代码，并能够复制您的问题。这是由于iOS上使用http连接而不是https的新限制。就像我在评论中提到的，用UnityWebRequest代替WWW解决了这个问题。
另外，每次执行new Texture2D(1280, 1280, TextureFormat.RGB24, false);时都不必要地创建新的纹理。这应该用Unity的UI组件RawImage来完成。在这种情况下，没有不必要的内存分配。
你所要做的就是删除WWW API并使用UnityWebRequest。也删除Renderer或Texture2D，并使用RawImage来显示您的地图。下面是我用来测试这一点的一个简单的测试脚本。它可以在Editor, iOS和可能的所有其他平台上运行。
