Select a Cell in a TableView and changed size

Question

I need to set my UITableView cells, when I select a cell increases its size to twice, and if I select another this increase in size and decrease that was previously selected size.

- (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section {
    return [self.states count];
}

- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath {
    static NSString *simpleTableIdentifier = @"SimpleTableCell";

    SimpleTableCell *cell = (SimpleTableCell *)[tableView dequeueReusableCellWithIdentifier:simpleTableIdentifier];
    if (cell == nil)
    {
        NSArray *nib = [[NSBundle mainBundle] loadNibNamed:@"SimpleTableCell" owner:self options:nil];
        cell = [nib objectAtIndex:0];
    }

    cell.stateName.text = [self.states objectAtIndex:indexPath.row];
    return cell;
}

-(CGFloat) tableView:(UITableView *)tableView heightForRowAtIndexPath:(NSIndexPath *)indexPath
{
    return 40;
}

@end

Answer 1

If you are using autolayout then simply add

-(CGFloat) tableView:(UITableView *)tableView heightForRowAtIndexPath:(NSIndexPath *)indexPath
{
    // for particular index 
    return UITableViewAutomaticDimension;
}

and if not using autolayout then

-(CGFloat) tableView:(UITableView *)tableView heightForRowAtIndexPath:(NSIndexPath *)indexPath
    {
        if(indexPath.row == 1){
           return 80;
        }else{
          return 44;
        }
    }

Answer 2

Take

one property selectedIndexPath

@property (strong, nonatomic) NSIndexPath * selectedIndexPath;

set that in

- (void)tableView:(UITableView *)tableView
    didSelectRowAtIndexPath:(NSIndexPath *)indexPath {
 selectedIndexPath = indexPath;
[tableView reloadData];
}


-(CGFloat) tableView:(UITableView *)tableView heightForRowAtIndexPath:(NSIndexPath *)indexPath
{
if(selectedIndexPath != nil && indexPath == selectedIndexPath){
        return 80;
}

    return 40;
}
