Custom cell UITextField updated in all cells across all sections

Question

This is a dynamic prototype UITableView: In my cellForRowAtIndexPath:

1. I have dequequed my custom cell and this works just fine:

   TimeSetViewCell *cell = [_tableView dequeueReusableCellWithIdentifier:@"timeCell" forIndexPath:indexPath];
   

2. Next I set TimePicker to UITextField in timeCell and this works fine as well (i.e. the time picker displayed onclick of UITextField in timeCell) :

   // Start Time
   UIDatePicker *sTimePicker = [[UIDatePicker alloc]init];
   sTimePicker.datePickerMode = UIDatePickerModeTime;
   sTimePicker.backgroundColor = [UIColor whiteColor]
   [cell.startTripTime setInputView:sTimePicker];
   
   // End Time
   UIDatePicker *eTimePicker = [[UIDatePicker alloc]init];
   eTimePicker.datePickerMode = UIDatePickerModeTime;
   eTimePicker.backgroundColor = [UIColor whiteColor];
   [cell.endTripTime setInputView:eTimePicker];
   

3. Next I wanted to update the cell's UITextField through an event, in which I have understood from @Mani's post, I have set:

   sTimePicker.tag = 1;
   eTimePicker.tag = 2;
   
   [sTimePicker addTarget:self action:@selector(updateTextField:)
        forControlEvents:UIControlEventValueChanged];
   [eTimePicker addTarget:self action:@selector(updateTextField:)
         forControlEvents:UIControlEventValueChanged];
   

   And in my custom method -(void)updateTextField:(UIDatePicker *)sender I have included this:

   //Date Formatter
   NSDateFormatter *dateFormat = [[NSDateFormatter alloc]init];
   [dateFormat setTimeStyle: NSDateFormatterShortStyle];
   
   if(sender.tag == 1){
   
       //Get Start Date
       UIDatePicker *starttimepicker = (UIDatePicker*)sender.inputView;
       thisStartTime = [starttimepicker date];
   
       //Display Date
       NSString *startTimeText = [dateFormat stringFromDate:thisStartTime];
       sTimeText = [NSString stringWithFormat:@"%@",startTimeText];
   
   }
   if(sender.tag == 2){
       //Get End Date
       UIDatePicker *endtimepicker = (UIDatePicker*)sender.inputView;
       thisEndTime = [endtimepicker date];
   
       //Display Date
       NSString *endTimeText = [dateFormat stringFromDate:thisEndTime];
       eTimeText = [NSString stringWithFormat:@"%@",endTimeText];
   }
   

Question Update

1. I managed to pass startTimeText and endTimeText to cell.startTripTime.text and cell.endTripTime.text through sTimeText and eTimeText.

2. And I used [_tableView reloadData]; in -(void)updateTextField:(UIDatePicker *)sender (after the two if blocks) and the data is displayed in my cell.startTripTimeand cell.endTripTime UITextField, but it appears the same in across of my sections, while I want it to change only the first section's time, how can I fix that?

   //I couldn't include the image but the output of the UITableView looks like this:
   
   _________________________
   Section 1
   _________________________
   Start Time : 4:50 PM
   _________________________
   End Time: 5:50 PM
   _________________________
   Section 2
   _________________________
   Start Time : 4:50 PM
   _________________________
   End Time: 5:50 PM
   _________________________
   

3. And the [_tableView reloadData]; seems to interfere and reloads the view while I haven't even finish picking the time that I wanted, how can I fix this too?

Answer 1

The action method should be sent to one of the picker, the startStripTime seems to be a UIView instance not a UIDatePicker instance.
It is he date picker that changes its value, not the view containing it.
You should change also the update method accordingly.
