本文介绍如何使用Objective-C在iOS设备上设置本地通知，包括定义通知时间、重复周期、图标角标数字、声音及警报内容等，并提供了取消通知的方法。

//发送通知

    UILocalNotification *notification=[[UILocalNotification alloc] init];   

    if (notification!=nil) { 

        NSDate *now=[NSDate new]; 

        notification.fireDate=[now dateByAddingTimeInterval:10];//10秒后通知

        notification.repeatInterval=0;//循环次数，kCFCalendarUnitWeekday一周一次

        notification.timeZone=[NSTimeZone defaultTimeZone];

        notification.applicationIconBadgeNumber=1; //应用的红色数字 

        notification.soundName= UILocalNotificationDefaultSoundName;//声音，可以换成alarm.soundName = @"myMusic.caf" 

        //去掉下面2行就不会弹出提示框

         notification.alertBody=@"通知内容";//提示信息 弹出提示框

         notification.alertAction = @"打开";  //提示框按钮 

        //notification.hasAction = NO; //是否显示额外的按钮，为no时alertAction消失



       // NSDictionary *infoDict = [NSDictionary dictionaryWithObject:@"someValue" forKey:@"someKey"];

        //notification.userInfo = infoDict; //添加额外的信息

        

        [[UIApplication sharedApplication] scheduleLocalNotification:notification];      

    }

    [notification release];

取消通知

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {    
    
    // Override point for customization after application launch.
    application.applicationIconBadgeNumber = 0;
    // Add the view controller's view to the window and display.
    [window addSubview:viewController.view];
    [window makeKeyAndVisible];

    return YES;
}
- (void)application:(UIApplication *)application didReceiveLocalNotification:(UILocalNotification *)notification {
    //点击提示框的打开
    application.applicationIconBadgeNumber = 0;
}
- (void)applicationDidBecomeActive:(UIApplication *)application {
    //当程序还在后天运行
    application.applicationIconBadgeNumber = 0;
}
