IOS本地推送：Unity内部封装了在iOS下的本地推送功能，可以很方便的实现在iOS设备上的简单本地推送。

命名空间为：UnityEngine.iOS 在Unity中的代码和直接用swift的代码基本类似。具体代码实现：

static void NotificationMessage(string message, System.DateTime newDate, bool isRepeatDay) {        //推送时间需要大于当前时间     if (newDate > System.DateTime.Now)     {         UnityEngine.iOS.LocalNotificationlocalNotification = new UnityEngine.iO      S.LocalNotification();         localNotification.fireDate = newDate;         localNotification.alertBody = message;         localNotification.applicationIconBadgeNumber = 1;         localNotification.hasAction = true;         if (isRepeatDay)         {                //是否每天定期循环             localNotification.repeatCalendar = UnityEngine.iOS.CalendarIdentifier.C  hineseCalendar;//中国日历             localNotification.repeatInterval = UnityEngine.iOS.CalendarUnit.Day;//每日推送         }         localNotification.soundName = UnityEngine.iOS.LocalNotification.defaultSound Name;         UnityEngine.iOS.NotificationServices.RegisterForNotifications(UnityEngine.iOS.NotificationType.Alert | UnityEngine.iOS.NotificationType.Badge | UnityEngine.iOS.NotificationType.Sound);         //以特定的类型推送         UnityEngine.iOS.NotificationServices.ScheduleLocalNotification(localNotification);     } }    //游戏退出时调用 void OnApplicationQuit() {        //每天中午12点推送     NotificationMessage("每天中午12点推送", 12, true); }    //游戏进入后台时或者从后台进入前台时调用 void OnApplicationPause(bool paused) {        //程序进入后台时     if (paused)     {            //每天中午12点推送         NotificationMessage("每天12点推送", 12, true);     }     else     {            //程序从后台进入前台时         CleanNotification();     } }    //清除推送消息,在Awake中调用 void CleanNotification() {     UnityEngine.iOS.LocalNotification ln = new UnityEngine.iOS.LocalNotification();     ln.applicationIconBadgeNumber = -1;     UnityEngine.iOS.NotificationServices.PresentLocalNotificationNow(ln);     UnityEngine.iOS.NotificationServices.CancelAllLocalNotifications();     UnityEngine.iOS.NotificationServices.ClearLocalNotifications(); } 

Android本地推送：

要想实现推送机制，那么第一步便是需要完成unity与android之间的交互，也就是c#与java之间的互相调用。

}

public static void callLoginMethod(string methodName) {     CallActivityFunction(methodName); } private static void CallActivityFunction(string methodName, params object[] args)  {     #if UNITY_ANDROID     if(Application.platform != RuntimePlatform.Android)      {         return;     }     try      {         AndroidJavaClass jc = new AndroidJavaClass("com.unity3d.player.UnityPlayer");          AndroidJavaObject jo = jc.GetStatic<AndroidJavaObject>("currentActivity");          jo.Call(methodName, args);     }     catch(System.Exception ex)     {         Debug.LogWarning(ex.Message);     }     #endif }

至于java调用c#，因为推送暂时用不到，就不说了，也很简单，需要的可以自己去查下

android推送不比ios，ios总得来说是对开发者友好的，只需要启动一个推送，然后设置更新时间，就可以隔一段时间自动推送了，然而android不能，写一个推送，只能在你指定的时间推送一次，因此，要实现定时推送，就必须配合计时器使用了。

首先说下android定时器

还需要实现一个receiver类，”com.XXX.XXX.MyReceiver”，该类继承自BroadcastReceiver。

     JSONObject json = new JSONObject();          try {             json.put("message", message);             json.put("seconds",seconds);             json.put("notificationId",notificationId);         } catch (JSONException e) {             // TODO Auto-generated catch block             e.printStackTrace();         }          Intent intent = new Intent(this,MyReceiver.class);          intent.putExtra("json",json.toString());           // get the AlarmManager instance            AlarmManager am= (AlarmManager) getSystemService(ALARM_SERVICE);           // create a PendingIntent that will perform a broadcast           PendingIntent pi= PendingIntent.getBroadcast(UnityPlayerNativeActivity.this, 0, intent, 0);           // just use current time + 10s as the Alarm time.            Calendar c=Calendar.getInstance();          c.setTimeInMillis(System.currentTimeMillis());         c.setTimeZone(TimeZone.getTimeZone("GMT+8"));         //可以根据项目要求修改，秒、分钟、提前、延后         c.add(Calendar.SECOND, seconds);         // schedule an alarm           am.setRepeating(AlarmManager.RTC_WAKEUP, c.getTimeInMillis(),86400000, pi);     }

定时器就是通过广播的形式，建立一个长连接，然后在receiver类里面实现public void onReceive(Context context, Intent intent) { }方法，这样到了定时器设定的时间，就会走onRecevie方法，在该方法里面，即可实现推送逻辑，json也会通过透传的方式传递过来，String jasonStr = intent.getStringExtra(“json”);即可得到json字符串，然后起一个推送即可。

 public static void registerLocalNotification(final Context context, final int seconds , final String message, final int notificationId) {        Builder notification = new Notification.Builder(context);            Resources res = context.getResources();         int app_icon = res.getIdentifier("app_icon", "drawable", context.getPackageName());         int app_name = res.getIdentifier("app_name", "string", context.getPackageName());         String title = context.getString(app_name);         Intent intent = new Intent(context, UnityPlayerNativeActivity.class);         PendingIntent contentIntent = PendingIntent.getActivity(context, app_name, intent, PendingIntent.FLAG_UPDATE_CURRENT);         notification.setAutoCancel(true);          notification.setContentTitle(title);         notification.setContentIntent(contentIntent);         notification.setContentText(message);         notification.setSmallIcon(app_icon);         notification.setWhen(System.currentTimeMillis());         final Notification notify = notification.build();          getNotificationManager(context).notify(notificationId,notify);    }      private static NotificationManager getNotificationManager(Context context) {         return (NotificationManager) context.getSystemService(Context.NOTIFICATION_SERVICE);     }

按照要求设置好信息以后，就可以正常推送了，注意图标一定要设置正确，否则推送无法正常显示。
