Countdown timer in UILabel in hidden UITableview section - uitableview

Question

I have an UIView in each section's header as a subview. That View contains start button and a label with countdown timer.
So when the timer is started and the Tableview scrolls, some sections become hidden than shown again, it re creates my View and resets the timer.
- (UIView *)tableView:(UITableView *)tableView viewForHeaderInSection:(NSInteger)section{
NSString *arrowName = [arrows objectAtIndex:section];
Workouts *workout = [workoutsArray objectAtIndex:section];
UIView* header;
if (section == 0) {
header = [[UIView alloc] initWithFrame:CGRectMake(0, 0, tableView.frame.size.width, 76)];
} else header = [[UIView alloc] initWithFrame:CGRectMake(0, 0, tableView.frame.size.width, 68)];
header.backgroundColor = [UIColor colorWithRed:0.133f green:0.125f blue:0.247f alpha:1.00f];
//The View with Timer Label
TodayWorkoutView* headerView = [[TodayWorkoutView alloc] initWithFrame:CGRectMake(16, header.frame.size.height-60, header.frame.size.width-32, 60)];
headerView.workout = workout;
[header addSubview:headerView];
return header;
}
How can I make timers in each section, that will work when TableView is scrolling?

Answer 1

I found one solution.
In viewDidLoad method init all Views and add to the new Array:
for (WeekDaysWorkouts *weekWorkout in [self getWokrouts]){
Workouts *fullWorkout = weekWorkout.workouts;
[workoutsArray addObject:fullWorkout];
TodayWorkoutView* headerView = [[TodayWorkoutView alloc] init];
headerView.workout = fullWorkout;
[headerViewsArray addObject:headerView];
}
Then I added Views to the section view:
- (UIView *)tableView:(UITableView *)tableView viewForHeaderInSection:(NSInteger)section{
NSString *arrowName = [arrows objectAtIndex:section];
UIView* header;
if (section == 0) {
header = [[UIView alloc] initWithFrame:CGRectMake(0, 0, tableView.frame.size.width, 76)];
} else header = [[UIView alloc] initWithFrame:CGRectMake(0, 0, tableView.frame.size.width, 68)];
header.backgroundColor = [UIColor colorWithRed:0.133f green:0.125f blue:0.247f alpha:1.00f];
//The View with Timer Label
TodayWorkoutView* headerView = [headerViewsArray objectAtIndex:section];
headerView.frame = CGRectMake(16, header.frame.size.height-60, header.frame.size.width-32, 60);
[header addSubview:headerView];
return header;}
So, all timers work without interruption, even when scrolling.
If anyone knows better solution, please let me know.
