Custom cell UITextField updated in all cells across all sections - ios

Question

This is a dynamic prototype UITableView: In my cellForRowAtIndexPath:
I have dequequed my custom cell and this works just fine:
TimeSetViewCell *cell = [_tableView dequeueReusableCellWithIdentifier:#"timeCell" forIndexPath:indexPath];
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];
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
I managed to pass startTimeText and endTimeText to cell.startTripTime.text and cell.endTripTime.text through sTimeText and eTimeText.
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
_________________________
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.
