// 1、打开本地推送并设置属性

NSString *str = @"本地推送的信息";

         UIApplication *app = [UIApplication sharedApplication];

         UILocalNotification *notification = [[UILocalNotification alloc]init];//初始化本地推送

         notification.soundName = UILocalNotificationDefaultSoundName;//设置声音

         notification.alertBody = str;//设置推送的消息

         [app scheduleLocalNotification:notification];//实现本地推送的关键步骤，

         [notification release];

         [str release];  

// 通过上面的方法可以实现推送的效果

2、本地推送的接受方法

- (void)application:(UIApplication *)application didReceiveLocalNotification:(UILocalNotification *)notification
