Google静态地图不会在iOS设备中加载 [英] Google static maps don´t load in iOS devices

问题描述

我在Unity中编写游戏，我需要加载静态地图。地图正确显示在编辑器和Android设备中，但不在iOS设备中。它说网址不正确......我不知道解决方案是什么。有谁能够帮助我？

I'm programming a game in Unity and I need to load a static map. The map are correctly displayed in the editor, and in Android devices, but not in iOS devices. It says the url is incorrect... I don´t know what is the solution. Can anybody help me?

我用以下代码调用地图：

I call the map with this code:

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;

这是调用网址的完整代码：

This is the full code to call the url:

推荐答案

在您的问题中运行代码并能够复制您的问题。这是因为在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那样，用 UnityWebRequest 替换 WWW 解决了这个问题。

Ran the code in your question and was able to replicate your problem. This is happening due to new restriction on using http connections instead of https on iOS. Just like I mentioned in my comment, replacing WWW with UnityWebRequest solved this problem.

此外，每次使用 new Texture2D（1280,1280，TextureFormat.RGB24，false）时，您都不必要地创建新纹理; 已执行。这应该使用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。

Also, you are unnecessarily creating new textures each time with new Texture2D(1280, 1280, TextureFormat.RGB24, false); is executed. This should be done with Unity's UI Component RawImage. In this case, no unnecessary memory allocation.

你需要做的就是删除 WWW API并使用 UnityWebRequest 。同时删除渲染器或 Texture2D 并使用 RawImage 显示您的地图。下面是我用来测试这个的简单测试脚本。它运行在编辑器， iOS 以及可能所有其他平台上。

All you have to do to the code in your question is to remove the WWW API and use UnityWebRequest. Also remove Renderer or Texture2D and use RawImage to display your map. Below is a simple test script I used to test this. It runs on the both Editor,iOS and possibly all other platforms.

public class Gpsconnect : MonoBehaviour
{
    public RawImage imageDisp;
    public float fixLat = 42.3627f;
    public float fixLon = -71.05686f;
    public int zoom = 4;
    public string key = "";
    public Vector3 iniRef;
    public Transform cam;
    private Camera mycam;
    private string url = "";

    //Update Map with the corresponding map images for the current location ============================================
    IEnumerator load()
    {
        yield return null;
        mycam = Camera.main;
        fixLat = ((360 / Mathf.PI) * Mathf.Atan(Mathf.Exp(0.00001567855943f * (cam.position.z - 3 * mycam.orthographicSize / 2 + iniRef.z)))) - 90;
        fixLon = (18000 * (cam.position.x + iniRef.x)) / 20037508.34f;

        //MAP ================================================================================
        //Build a valid Google Maps tile request for the current location 

        url = "https://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" + "&sensor=false&key=" + key;

        UnityWebRequest www = UnityWebRequest.GetTexture(url);
        yield return www.Send();
        Debug.Log("Done: ");

        if (www.isError)
        {
            Debug.Log("Error while downloading image: " + www.error);
        }
        else
        {
            imageDisp.texture = ((DownloadHandlerTexture)www.downloadHandler).texture;
        }
    }

    void Start()
    {
        StartCoroutine(load());
    }
}
