如何统一截取可用于 IOS 和 Android 的屏幕截图

Question

如何截取屏幕截图，以便我可以统一截取游戏截图，以便将其保存到 IOS 和 Android 的图库中。

using System.Collections;
using System.Collections.Generic;
using UnityEngine;
using UnityEngine.UI;

public class TakeScreenshot : MonoBehaviour {

    [SerializeField]
    GameObject blink;
    public Text text;
    public Transform canvas;

    protected const string MEDIA_STORE_IMAGE_MEDIA = "android.provider.MediaStore$Images$Media";
    protected static AndroidJavaObject m_Activity;

    public void TakeAShot()
    {
        StartCoroutine(CaptureIt(Screen.width, Screen.height));
    }

    IEnumerator CaptureIt(int width, int height)
    {
        yield return new WaitForEndOfFrame();
        Texture2D tex = new Texture2D(width, height);
        tex.ReadPixels(new Rect(0, 0, width, height), 0, 0);
        tex.Apply();

        yield return tex;
        string path = SaveImageToGallery(tex, "Name", "Description");
        Debug.Log("Picture has been saved at:\n" + path);
    }

    protected static string SaveImageToGallery(Texture2D a_Texture, string a_Title, string a_Description)
    {
        using (AndroidJavaClass mediaClass = new AndroidJavaClass(MEDIA_STORE_IMAGE_MEDIA))
        {
            using (AndroidJavaObject contentResolver = Activity.Call<AndroidJavaObject>("getContentResolver"))
            {
                AndroidJavaObject image = Texture2DToAndroidBitmap(a_Texture);
                return mediaClass.CallStatic<string>("insertImage", contentResolver, image, a_Title, a_Description);
            }
        }
    }

    protected static AndroidJavaObject Texture2DToAndroidBitmap(Texture2D a_Texture)
    {
        byte[] encodedTexture = a_Texture.EncodeToPNG();
        using (AndroidJavaClass bitmapFactory = new AndroidJavaClass("android.graphics.BitmapFactory"))
        {
            return bitmapFactory.CallStatic<AndroidJavaObject>("decodeByteArray", encodedTexture, 0, encodedTexture.Length);
        }
    }

    protected static AndroidJavaObject Activity
    {
        get
        {
            if (m_Activity == null)
            {
                AndroidJavaClass unityPlayer = new AndroidJavaClass("com.unity3d.player.UnityPlayer");
                m_Activity = unityPlayer.GetStatic<AndroidJavaObject>("currentActivity");
            }
            return m_Activity;
        }
    }

}

我已经使用此方法在 android 库中截取并保存屏幕截图，但无法在 IOS 中保存相同的截图。 有人可以帮我吗？

我尝试使用建议的编辑，但仍然没有运气。 现在我的代码看起来像这样。

public void TakeAShot()
{
    StartCoroutine(TakeScreenshotAndSave());
}

private IEnumerator TakeScreenshotAndSave()
{
    yield return new WaitForEndOfFrame();

    Texture2D ss = new Texture2D(Screen.width, Screen.height, TextureFormat.RGB24, false);
    ss.ReadPixels(new Rect(0, 0, Screen.width, Screen.height), 0, 0);
    ss.Apply();

    // Save the screenshot to Gallery/Photos
    Debug.Log("Permission result: " + NativeGallery.SaveImageToGallery(ss, "GalleryTest", "Image.png"));

    // To avoid memory leaks
    Destroy(ss);
}
