Unity3D截屏录屏后存储IOS安卓系统相册

此方法采用U3D和ios和安卓交互方法完成具体内容是U3D写出调用IOS和安卓方法传递录像和照片的沙盒路径存储由安卓和ios来完成好了我们先上U3D代码

using UnityEngine;
using System.Collections;
using System.Collections.Generic;
using System;public class SelectPlatform : MonoBehaviour {#if UNITY_ANDROID/// <summary>/// Android平台接口/// </summary>public static AndroidInterface android=new AndroidInterface();#elif UNITY_IPHONE/// <summary>/// IOS平台接口/// </summary>public static IOSInterface ios=new IOSInterface();#endif/// <summary>/// 对Android或IOS接口进行调用/// </summary>public static void SendMessage(string funName,string data){#if UNITY_ANDROIDType type = typeof(AndroidInterface);type.GetMethod(funName).Invoke(android,new object[]{data});#elif UNITY_IPHONEType type = typeof(IOSInterface);type.GetMethod(funName).Invoke(ios,new object[]{data});#endif}
}

#if UNITY_ANDROID
using UnityEngine;
using System.Collections;
/// <summary>
/// 安卓方法列表
/// </summary>
public class AndroidInterface : AbstractClass {/// <summary>/// 关闭U3D/// </summary>/// <param name="data"></param>public override void CloseUnity(string data){Debug.Log("CloseUnity");MyAndroidPlayer.SendMessage("CloseUnity", data);}/// <summary>/// 保存照片/// </summary>/// <param name="data"></param>public override void PreservationSPhoto(string data){Debug.Log("PreservationSPhoto");MyAndroidPlayer.SendMessage("PreservationSPhoto", data);}/// <summary>/// 保存录像/// </summary>/// <param name="data"></param>public override void PreservationSvideotape(string data){Debug.Log("PreservationSvideotape");MyAndroidPlayer.SendMessage("PreservationSvideotape", data);}
}
#endif

using UnityEngine;
using System.Collections;
/// <summary>
/// 方法列表
/// </summary>
public  abstract class AbstractClass  {/// <summary>/// 关闭U3D/// </summary>/// <param name="data"></param>public abstract void CloseUnity(string data);/// <summary>/// 保存照片/// </summary>/// <param name="data"></param>public abstract void PreservationSPhoto(string data);/// <summary>/// 保存录像/// </summary>/// <param name="data"></param>public abstract void PreservationSvideotape(string data);
}

using UnityEngine;
using System.Collections;
#if UNITY_ANDROID
public class MyAndroidPlayer : MonoBehaviour {public delegate void ObtainMessageDelegate(string messageType, string message);public static ObtainMessageDelegate ObtainMessage;private static AndroidJavaClass androidJavaClass;private static AndroidJavaObject androidJavaObject;private char SEPARATOR = '~';void Awake(){if (Application.platform != RuntimePlatform.Android) return;androidJavaClass = new AndroidJavaClass("com.unity3d.player.UnityPlayer");androidJavaObject = androidJavaClass.GetStatic<AndroidJavaObject>("currentActivity");//  androidJavaObject = androidJavaObject.Get<AndroidJavaObject>("functionUnity");}public static void SendMessage(string method, string msgArgs){Debug.Log(method);androidJavaObject.Call(method, new string[] { msgArgs });}
}#endif

using UnityEngine;
using System.Collections;
using System.Runtime.InteropServices;
using System;public class IOSInterface : AbstractClass {[DllImport("__Internal")]private static extern void _CloseUnity(string wenwen);public override void CloseUnity(string wenwen){_CloseUnity(wenwen);}[DllImport("__Internal")]private static extern void _PreservationSPhoto(string wenwen);public override void PreservationSPhoto(string wenwen){_PreservationSPhoto(wenwen);}[DllImport("__Internal")]private static extern void _PreservationSvideotape(string wenwen);public override void PreservationSvideotape(string wenwen){_PreservationSvideotape(wenwen);}
}

以上是我对调用ios 安卓方法做的一个小模块处理然后我们在以后的项目里就很好的调用了例如

 public void  CloseUnity(){SelectPlatform.SendMessage("CloseUnity", "退出U3D");}public void PreservationSPhoto(string data){SelectPlatform.SendMessage("PreservationSPhoto",data);}public void PreservationSvideotape(string data){SelectPlatform.SendMessage("PreservationSvideotape",data);}

然后方法的参数就是我们做完截屏和录屏的路径截屏代码我就不提供了百度一堆录屏各种插件或者自己写最后传递参数例如 Debug.Log(“录像存储地址” + Application.persistentDataPath + “/” + filePath);
注意路径 Application.persistentDataPath

写好方法后我们先来安卓导出AS项目这里说明一些如果公司有安卓 ios程序最好和他们沟通好接口
如果没有就需要自己来写了下面贴代码找到 java里 UnityPlayerActivity

package com.itemjia.app.bandian;import com.unity3d.player.*;

}

新建一个 .java代码 ImgUtils

package com.itemjia.app.bandian;import android.content.Context;
import android.content.Intent;
import android.graphics.Bitmap;
import android.media.MediaScannerConnection;
import android.net.Uri;
import android.os.Build;
import android.os.Environment;
import android.provider.MediaStore;import java.io.File;
import java.io.FileNotFoundException;
import java.io.FileOutputStream;
import java.io.IOException;public class ImgUtils {/** 保存文件，文件名为当前日期*/public static void saveBitmap(Bitmap bitmap, String bitName,Context context) {String fileName;File file;if (Build.BRAND.equals("xiaomi")) { // 小米手机fileName = Environment.getExternalStorageDirectory().getPath() + "/DCIM/Camera/" + bitName;}else if (Build.BRAND.equals("Huawei")){fileName = Environment.getExternalStorageDirectory().getPath() + "/DCIM/Camera/" + bitName;} else {  // Meizu 、OppofileName = Environment.getExternalStorageDirectory().getPath() + "/DCIM/" + bitName;}file = new File(fileName);if (file.exists()) {file.delete();}FileOutputStream out;try {out = new FileOutputStream(file);// 格式为 JPEG，照相机拍出的图片为JPEG格式的，PNG格式的不能显示在相册中if (bitmap.compress(Bitmap.CompressFormat.JPEG, 90, out)) {out.flush();out.close();
// 插入图库MediaStore.Images.Media.insertImage(context.getContentResolver(), file.getAbsolutePath(), bitName, null);}} catch (FileNotFoundException e) {e.printStackTrace();} catch (IOException e) {e.printStackTrace();}// 发送广播，通知刷新图库的显示context.sendBroadcast(new Intent(Intent.ACTION_MEDIA_SCANNER_SCAN_FILE, Uri.parse("file://" + fileName)));}}

安卓代码完成下面来做IOS 如果你写了接口就必须实现不然会报错新创建一个.h文件就叫 u3dmanage.h吧

//
//  u3dmanage.h
//  Unity-iPhone
//
//  Created by Gy on 2020/4/26.
//
@interface u3dmanage : NSObject
void _CloseUnity(char*msg);
void _PreservationSPhoto(char*msg);
void _PreservationSvideotape(char*msg);
@end
#ifndef u3dmanage_h
#define u3dmanage_h#endif /* u3dmanage_h */

这个是接口在写实现代码
创建一个 .m文件 u3dmanage.m

//
//  u3dmanage.m
//  Unity-iPhone
//
//  Created by Gy on 2020/4/27.
//#import "u3dmanage.h"
@interface u3dmanage ();
@end
@implementation u3dmanagevoid _CloseUnity(char* msg){NSString *string1 = [[NSString alloc] initWithUTF8String:msg];NSString *string2 = [[NSString alloc] initWithUTF8String:msg];NSLog(@"###%@", [NSString stringWithFormat:@"%@ %@", string1, string2]);}
void _PreservationSPhoto(char* msg){NSString *string1 = [[NSString alloc] initWithUTF8String:msg];NSString *string2 = [[NSString alloc] initWithUTF8String:msg];NSString *strReadAddr = [NSString stringWithUTF8String:msg];UIImage *img = [UIImage imageWithContentsOfFile:strReadAddr];NSLog([NSString stringWithFormat:@"w:%f, h:%f", img.size.width,img.size.height]);u3dmanage *instance = [u3dmanage alloc];UIImageWriteToSavedPhotosAlbum(img, instance,@selector(imageSaved:didFinishSavingWithError:contextInfo:), nil);NSLog(@"###%@", [NSString stringWithFormat:@"%@ %@", string1, string2]);}
void _PreservationSvideotape(char* msg){NSString *strReadAddr = [NSString stringWithUTF8String:msg];u3dmanage *instance = [u3dmanage alloc];UISaveVideoAtPathToSavedPhotosAlbum(strReadAddr, instance, nil, nil);}
+ (void) savedVedioImage:(UIImage*)image didFinishSavingWithError: (NSError *)error contextInfo: (void *)contextInfo {NSString* result;if (error) {result =@"视频保存失败";}else {result =@"保存视频成功";}//  UnitySendMessage( "MainScriptHolder", "SaveVedioToPhotosAlbumCallBack", result.UTF8String);
}
- ( void ) imageSaved: ( UIImage *) image didFinishSavingWithError:( NSError *)errorcontextInfo: ( void *) contextInfo
{NSLog(@"保存结束");if (error != nil) {NSLog(@"有错误");}
}@end
