Question

I have a UI which contains a UITableView and a UIDatePicker. When I select a Row on my table it is highlighted, but as soon as I interact with the DatePicker (scroll to a new value) the row isn’t highlighted anymore. The value of the row is bound to that of the DatePicker. How can I permanently highlight the cell?

In the iCal-App -> Add -> Start&End I saw this behaviour.
I tried the selectRowAtIndex method in my ValueChanged-method of the picker. I thought that the highlighting is lost in this callback-method.

-(IBAction)setStartTimeMethod
{

    NSDateFormatter *dateFormat = [[NSDateFormatter alloc] init];   
    [dateFormat setDateFormat:@"EEE, dd. MMM yyyy  HH:mm"];


    if(!self.endDateRowSelected)
        self.date = [dateFormat stringFromDate:[datePicker date]];
    else
        self.endDate = [dateFormat stringFromDate:[datePicker date]];
    [dateFormat release];
//    [self.tableView1 selectRowAtIndexPath:tableView1.indexPathForSelectedRow animated:NO scrollPosition:UITableViewScrollPositionTop];
    [self.tableView1 reloadData];

}

Edit, my didSelectRowMethod

- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath
{

    NSDateFormatter *formatter = [[NSDateFormatter alloc] init];
    [formatter setDateFormat:@"EEE, dd. MMM yyyy  HH:mm"];

    if(indexPath.row == 0){
        NSLog(@"Start");
        self.endDateRowSelected = NO;


        NSDate *startDate = [formatter dateFromString:self.date];
        [datePicker setDate:startDate animated:YES];

        //if(self.endDateRowSelected)
          //  [tableView selectRowAtIndexPath:indexPath animated:YES scrollPosition:UITableViewScrollPositionNone];

    }else if(indexPath.row == 2){
        NSLog(@"End");
        self.endDateRowSelected = YES;

        if(self.endDate){
            NSDate *endDateTime = [formatter dateFromString:self.endDate];
            [datePicker setDate:endDateTime animated:YES];
        }
    }else{
        self.endDateRowSelected = NO;
    }

    [formatter release];
//    Won't work, doesn't allow highlighting a cell.
//    [tableView deselectRowAtIndexPath:indexPath animated:NO];

}

The solution was quite easy.

In my cellForRowAtIndexPath I must call the selectRowAtIndexPath method.

...
if(indexPath.row == 0){
                cell.description.text = [dict objectAtIndex:indexPath.row];
                cell.dateTime.text = self.startDate;

                if(!endDateRowSelected)
                    [tableView selectRowAtIndexPath:indexPath animated:NO scrollPosition:UITableViewScrollPositionNone]; 
            }else if(indexPath.row == 2){
                cell.description.text = [dict objectAtIndex:indexPath.row];
                cell.dateTime.text = self.endDate;
                if(endDateRowSelected)
                    [tableView selectRowAtIndexPath:indexPath animated:NO scrollPosition:UITableViewScrollPositionNone]; 
            }
...

The bool is set in my didSelectRowAtIndexPath, depending on clicking on Start or End.
I still reload the table in my pickerValueChanged delegate.

Thank you for time & help.
