    [DllImport("__Internal")]
    private static extern void _SavePhoto(string readAddr);
    public void Stt()
    {
        //获取系统时间并命名相片名  
        System.DateTime now = System.DateTime.Now;
        string times = now.ToString();
        times = times.Trim();
        times = times.Replace("/", "-");
        string filename = "Screenshot" + times + ".png";
        string Path_save;
        //判断是否为IOS平台  
        if (Application.platform == RuntimePlatform.IPhonePlayer)
        {

            //截取屏幕  
            Texture2D texture = new Texture2D(Screen.width, Screen.height, TextureFormat.RGB24, false);
            texture.ReadPixels(new Rect(0, 0, Screen.width, Screen.height), 0, 0);
            texture.Apply();
            //转为字节数组  
            byte[] bytes = texture.EncodeToPNG();

           

            string destination = Application.persistentDataPath;
            

            Path_save = destination + "/" + filename;
            //存图片  
            File.WriteAllBytes(Path_save, bytes);
            var readAddr = Path_save;
            _SavePhoto(readAddr);

        }
    }

我在unity里是这样写的，做成按钮的click

在Xcode里加了下面两个脚本




拍照后在相册中查看，全是存的黑色图片，是为啥啊？好痛苦
