Timer Object value is not passing through sender in an instance - ios

Question

This Application sends data (through a dictionary) two following instances to other views from the sender.
Home Page TableviewCell to each particular view according to each state
Ex- IF state 1 - AppointmentView 2 - OnthewayView 3 - TimerView 4 - Invoice View.
Home ---> Appointment
Home ---> ontheWay
Home ---> TimerView
Home ---> Invoice
Home ---> AppointmentView ---> ontheway --> timer ---> Invoice
I have an issue when I navigating timer --> Invoice the timer going as empty timer = "" so some of my functions (time fee calculation) are not working on this instance only.
But the same as 1st instance when I go back to Home and Home -> invoice timer=10 and rest of the functions works.
code snippet for 1st instance (the working one) (homeviewcontroller)
- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath{
if (indexPath.section==0) {
if (bookingArray.count) {
NSInteger keyStatus =[bookingArray[indexPath.row][#"status"] integerValue] ;
switch (keyStatus) {
case 2:
[self performSegueWithIdentifier:#"appointmentDetail" sender:bookingArray[indexPath.row]];
break;
case 5:
[self performSegueWithIdentifier:#"ToMapController" sender:bookingArray[indexPath.row]];
break;
case 6:
[self performSegueWithIdentifier:#"ToTimerVC" sender:bookingArray[indexPath.row]];
break;
case 21:
[self performSegueWithIdentifier:#"ToTimerVC" sender:bookingArray[indexPath.row]];
break;
case 22:
[self performSegueWithIdentifier:#"ToInvoice" sender:bookingArray[indexPath.row]];
break;
}
