Just use:
NSPredicate *predicate = [NSPredicate predicateWithFormat:@"userInfo.WeekDay = %d", yourWeekDay];
or:
NSPredicate *predicate = [NSPredicate predicateWithFormat:@"userInfo.Timeid = %d", yourTimeID];
Then:
NSArray *notifications = [[[UIApplication sharedApplication] scheduledLocalNotifications] filteredArrayUsingPredicate:predicate];
