ios 通知

苹果的通知分为本地通知和远程通知

• 若用户直接启动，lauchOptions内无数据;
• 若由其他应用程序通过openURL:启动，则UIApplicationLaunchOptionsURLKey对应的对象为启动URL（NSURL）,UIApplicationLaunchOptionsSourceApplicationKey对应启动的源应用程序的bundle ID (NSString)；
• 若由本地通知启动，则UIApplicationLaunchOptionsLocalNotificationKey对应的是为启动应用程序的的本地通知对象(UILocalNotification)；
• 若由远程通知启动，则UIApplicationLaunchOptionsRemoteNotificationKey对应的是启动应用程序的的远程通知信息userInfo（NSDictionary）；
• 其他key还有UIApplicationLaunchOptionsAnnotationKey,UIApplicationLaunchOptionsLocationKey,
  UIApplicationLaunchOptionsNewsstandDownloadsKey。

当应用在前台时，本地通知没有声音

      NSURL *url = [options objectForKey:UIApplicationLaunchOptionsURLKey];
      if(url)
      {
      }
      NSString *bundleId = [options objectForKey:UIApplicationLaunchOptionsSourceApplicationKey];
      if(bundleId)
      {
      }
