UILocalNotification 的使用

- (UILocalNotification*) createLocalNotificationWithContent:(NSString*) content{
    UILocalNotification *notification=[[[UILocalNotification alloc] init] autorelease];
    if (notification!=nil) {
        
        NSDate *now=[NSDate new];
        NSLog(@"now:%@",now);
        notification.fireDate=[now dateByAddingTimeInterval:diff];//10秒后通知

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

        notification.timeZone=[NSTimeZone localTimeZone];
        notification.applicationIconBadgeNumber = 1; //应用的红色数字
        
        notification.soundName= UILocalNotificationDefaultSoundName;
        
        //去掉下面2行就不会弹出提示框
        notification.alertBody = [NSString stringWithFormat:@"活动：%@",content];//提示信息 弹出提示框
        notification.alertAction = @"打开";  //提示框按钮
        notification.hasAction = YES; //是否显示额外的按钮，为no时alertAction消失
        NSDictionary *infoDict = [NSDictionary dictionaryWithObject:@"information"];
        notification.userInfo = infoDict; //添加额外的信息

    }
    return notification;
}
- (void) pushLocalNotificationWith:(UILocalNotification*) localNotification{
    [[UIApplication sharedApplication] scheduleLocalNotification:localNotification];
}
- (void) popAndCancelLocalNotificationWith:(UILocalNotification*) localNotification{
    [[UIApplication sharedApplication] cancelLocalNotification:localNotification];
}
