In .h file create variable 

UItableviewCell *selectedCell;

In didSelectRow method remove selection from saved cell and save new cell as selected:

-(void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath 
    if (selectedCell) {
        selectedCell.accessoryType = UITableViewCellAccessoryNone;
    }
    UItableviewCell *cell = [tableView cellForRowAtIndexPath:indexPath];
    if(cell.accessoryType == UITableViewCellAccessoryCheckmark) {
        cell.accessoryType = UITableViewCellAccessoryNone;
    else {
        cell.accessoryType = UITableViewCellAccessoryCheckmark;
    }
    selectedCell = cell;
}

To prevent problems with reusable cells u can create NSIndexPath variable instead of UITableViewCell in .h file:

NSIndexPath *selectedCellIndexPath;

and change didSelectRow method:

-(void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath 
    [tableView scrollToRowAtIndexPath:selectedCellIndexPath atScrollPosition:UITableViewScrollPositionMiddle animated:NO];
    UITableViewCell *selectedCell = [tableView cellForRowAtIndexPath:selectedCellIndexPath];
    selectedCell.accessoryType = UITableViewCellAccessoryNone;
    UItableviewCell *cell = [tableView cellForRowAtIndexPath:indexPath];
    if(cell.accessoryType == UITableViewCellAccessoryCheckmark) {
        cell.accessoryType = UITableViewCellAccessoryNone;
    else {
        cell.accessoryType = UITableViewCellAccessoryCheckmark;
    }
    selectedCellIndexPath = indexPath;
}

First add a property to your viewController .h file 

@property (nonatomic, strong) NSIndexPath *theSelectedIndexPath;

and in your .m file synthesize

@synthesize theSelectedIndexPath = _theSelectedIndexPath;

Then in your cellForRowAtIndexPath do 

if (indexPath.row == self.theSelectedIndexPath.row) {
   cell.accessoryType = UITableViewCellAccessoryCheckmark;
}
else { 
   cell.accessoryType = UITableViewCellAccessoryNone;
}

Don't forget to update the theSelectedIndexPath in didSelectRowAtIndexPath

- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath
{
    self.theSelectedIndexPath = indexPath;
}

  1. declare a global int selectedRow
  2. in your tableviewDidSelectRow set that int to the selected row.
  3. also there in tableviewDidSelectRow make [tableView reloadData];

  4. in your tableView:(UITableView *)tableView cellForRowAtIndexPath do the following:

    if (indexPath.row == selectedRow)
    cell.accessoryView = checkMark;
else
    cell.accessoryView = nil;

where "checkMark" is an outlet to your checkmark imageview (I use custom checkmarks)

Tada!
