纠正一点错误（注意看一下红字部分） UnitySendMessage回调unity中的函数，但是这个回调需要一定的时间响应，假如在UnitySendMessage后面立即 UnityPause(true);就会导致unity程序立即暂停，引发回调的函数未被执行。所以采用 [self performSelector:@selector(waitSaveData) withObject:nil afterDelay:1]; 延迟1秒钟在调用暂停可以确保数据保存

双击Home键退出程序调用此函数实现数据保存

- (void) applicationWillResignActive:(UIApplication*)application
{printf_console("-> applicationDidResignActive()\n");UnitySendMessage("data", "SaveDataIOS", @"AchievementData.txt".UTF8String);//新添加代码回调unity中data物体上的SaveDataIOS函数 SaveDataIOS函数实现文件保存[self performSelector:@selector(waitSaveData) withObject:nil afterDelay:1];_didResignActive = YES;
}-(void)waitSaveData{UnityPause(true);
}

双击Home 启动应用程序进入此函数读取数据

- (void) applicationDidBecomeActive:(UIApplication*)application
{printf_console("-> applicationDidBecomeActive()\n");if (_didResignActive){UnityPause(false);UnitySendMessage("data", "ReadDataIOS", @"data.txt".UTF8String);//新添加代码回调unity中data物体上的ReadDataIOS函数 ReadDataIOS函数实现文件读取
    }
}

辅助函数获取路径

public string JsonPath{get{   string    path=null;if(Application.platform==RuntimePlatform.IPhonePlayer){path= Application.dataPath.Substring (0, Application.dataPath.Length - 5);path = path.Substring(0, path.LastIndexOf('/'))+"/Documents/"; }
            else if(Application.platform==RuntimePlatform.Android)
            {
                path= Application.persistentDataPath+"/";
            }else{path=Application.dataPath+"/Resource/GameData/";}return path;}  }

根据平台获取存放文件路径为ios设备存储到Documents文件夹下

读文件：

public void LoadDataWithFile(string txtName){string path=JsonPath+txtName;if(File.Exists(path)){FileStream  fs=new  FileStream(path,FileMode.Open);StreamReader sr=new StreamReader(fs);FileData = JsonMapper.ToObject(sr.ReadToEnd());sr.Close();fs.Close();}else{Debug.Log("No json ");}  }

写文件

    public void WriteDataWithFile(string txtName,string content){string path=JsonPath+txtName;FileStream fs;if(!File.Exists(path)){fs=new  FileStream(path,FileMode.Create);}else{fs=new  FileStream(path,FileMode.Truncate);//注意对存在文件内容替换
        }StreamWriter sw=new StreamWriter(fs);sw.Write(content);sw.Close();fs.Close();  }
