I am adding the code too . `- (void)prepareForSegue:(UIStoryboardSegue *)segue sender:(id)sender {

    NSIndexPath *indexPath = [self.placeTableViewController indexPathForSelectedRow];
    NomadPlaceDetailViewController *placedetailcontroller = segue.destinationViewController;
    placedetailcontroller.myDictionary = [self.placeArray objectAtIndex:indexPath.row];

Answer 1

This is because of your cell identifier try this code. Hope this may help you.

- (UITableViewCell *) tableView:(UITableView *) tableView1 cellForRowAtIndexPath:(NSIndexPath *) indexPath 
{

static NSString *CellIdentifier = nil;

   UITableViewCell *cell = (UITableViewCell*) [tableView dequeueReusableCellWithIdentifier:CellIdentifier];

    if (cell == nil)
    {        
        cell = [[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:CellIdentifier];
    }
   return cell;

}

When you are using dequeueReusableCellWithIdentifier: then it is best practice to reuse it's subviews also if you are adding additional subviews in cell.

You can write your cellForRowAtIndexPath like following:

- (UITableViewCell *) tableView:(UITableView *) tableView1 cellForRowAtIndexPath:(NSIndexPath *) indexPath 
{

    static NSString *CellIdentifier = @"CellIdentifier";

    UITableViewCell *cell = (UITableViewCell*) [tableView dequeueReusableCellWithIdentifier:CellIdentifier];

    UITextField *myView;

    if (cell == nil)
    {        
        cell = [[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:CellIdentifier];

        myView = [[UITextField alloc] init];  // Set frame as required
        myView.tag = indexPath.row;
        [cell.contentView addSubview:myView];
    }

    myView = [cell.contentView viewWithTag:indexPath.row];
    myView.text = @"YourText";
   return cell;

}

What happens here is it adds myView only once when cell is nil , and after that it will reuse previously added myView to set Text so myView will not be added multiple times and that solves problem.

This is because you initialize and adding the labels outside of if(cell == nil) condition. So every time you scroll the table view, the code for adding labels executed and new labels creating. So just place them inside of your if(cell == nil) condition. Only data displaying section should place outside if(cell == nil) .
