截屏和录屏unity端代码都已经分享过 :
Unity功能记录(十七) ------ 截屏功能
Unity插件(二) ------ NatCorder(录屏保存到相册)

但是之前一个个的其实并没有用在项目上,可能会有点小坑,因此此次用在项目上的完整代码再次记录一下

一.截屏

Unity端代码 :
  1.  void RecordFrame()
  2.     {
  3.         DateTime now = new DateTime();
  4.         now = DateTime.Now;
  5.         string filename = string.Format("image{0}{1}{2}{3}.png", now.Day, now.Hour, now.Minute, now.Second);
  6.         Texture2D texture = CaptureScreen(ARControll.Instance.CaptureCamera,new Rect(0,0,Screen.width,Screen.height));
  7.         string destination = "";
  8.         if (Application.platform == RuntimePlatform.Android)
  9.         {
  10.             destination = "/mnt/sdcard/DCIM/Screenshots";
  11.             if (!Directory.Exists(destination))
  12.             {
  13.                 Directory.CreateDirectory(destination);
  14.             }
  15.             destination = destination + "/" + filename;
  16.             Debug.Log(destination);
  17.             File.WriteAllBytes(destination, texture.EncodeToPNG());
  18.             // 安卓在这里需要去 调用原生的接口去 刷新一下，不然相册显示不出来
  19.             using (AndroidJavaClass playerActivity = new AndroidJavaClass("com.unity3d.player.UnityPlayer"))
  20.             {
  21.                 using (AndroidJavaObject jo = playerActivity.GetStatic<AndroidJavaObject>("currentActivity"))
  22.                 {
  23.                     Debug.Log("scanFile:m_androidJavaObject ");
  24.                     jo.Call("scanFile", destination);
  25.                 }
  26.             }
  27.             MainControll.Instance.OpenTip(TipType.OneBtn, TipContentType.defaultTip, null, null, "拍照成功!", PanelLayer.Top);
  28.         }
  29.         else if (Application.platform == RuntimePlatform.IPhonePlayer)
  30.         {
  31.             destination = Application.persistentDataPath;
  32.             if (!Directory.Exists(destination))
  33.             {
  34.                 Directory.CreateDirectory(destination);
  35.             }
  36.             destination = destination + "/" + filename;
  37.             File.WriteAllBytes(destination, texture.EncodeToPNG());
  38. #if UNITY_IOS
  39.             IOSAlbumCamera.iosSaveImageToPhotosAlbum(destination);
  40. #endif
  41.         }
  42.         else
  43.         {
  44.             File.WriteAllBytes(Application.persistentDataPath + filename, texture.EncodeToPNG());
  45.         }
  46.         // cleanup
  47.         Destroy(texture);
  48.     }
Android刷新相册代码 :
  1.    //刷新相册
  2.     public void scanFile(String filePath) {
  3.         //Log.i("Unity", "------------filePath"+filePath);
  4.         Intent scanIntent = new Intent(Intent.ACTION_MEDIA_SCANNER_SCAN_FILE);
  5.         scanIntent.setData(Uri.fromFile(new File(filePath)));
  6.         this.sendBroadcast(scanIntent);  //this是指UnityPlayerActivity
  7.     }
iOS保存图片到相册代码(这里一起放了保存视频到相册的代码) :

注意修改回调哦

二.录屏

unity代码请参考Unity插件(二) ------ NatCorder(录屏保存到相册)
保存到相册请参考一中iOS所有代码
