第一步：创建本地推送

// 创建一个本地推送UILocalNotification *notification = [[[UILocalNotificationalloc] init]autorelease];//设置10秒之后NSDate *pushDate = [NSDatedateWithTimeIntervalSinceNow:10];if (notification !=nil) {    // 设置推送时间    notification.fireDate = pushDate;    // 设置时区    notification.timeZone = [NSTimeZone defaultTimeZone];    // 设置重复间隔    notification.repeatInterval = kCFCalendarUnitDay;    // 推送声音    notification.soundName = UILocalNotificationDefaultSoundName;    // 推送内容    notification.alertBody = @"推送内容";    //显示在icon上的红色圈中的数子    notification.applicationIconBadgeNumber =1;    //设置userinfo方便在之后需要撤销的时候使用    NSDictionary *info = [NSDictionary dictionaryWithObject:@"name"forKey:@"key"];    notification.userInfo = info;    //添加推送到UIApplication    UIApplication *app = [UIApplication sharedApplication];    [app scheduleLocalNotification:notification];}

第二步：接收本地推送

- (void)application:(UIApplication *)application didReceiveLocalNotification:(UILocalNotification*)notification{    UIAlertView *alert = [[UIAlertView alloc] initWithTitle:@"iWeibo" message:notification.alertBody delegate:nil cancelButtonTitle:@"确定" otherButtonTitles:nil];    [alert show];    // 图标上的数字减1    application.applicationIconBadgeNumber -=1;}

第三步：解除本地推送

// 获得 UIApplicationUIApplication *app = [UIApplication sharedApplication];//获取本地推送数组NSArray *localArray = [app scheduledLocalNotifications];//声明本地通知对象UILocalNotification *localNotification;if (localArray) {    for (UILocalNotification *notiin localArray) {        NSDictionary *dict = noti.userInfo;        if (dict) {            NSString *inKey = [dict objectForKey:@"key"];            if ([inKey isEqualToString:@"对应的key值"]) {                if (localNotification){                    [localNotification release];                    localNotification =nil;                }                localNotification = [noti retain];                break;            }        }    }        //判断是否找到已经存在的相同key的推送    if (!localNotification) {        //不存在初始化        localNotification = [[UILocalNotification alloc] init];    }        if (localNotification) {        //不推送取消推送        [app cancelLocalNotification:localNotification];        [localNotification release];        return;    }}
