Try this. In your cellForRowAtIndexPath delegate method put the following code.

if (cell == nil) {
    ...
    [[cell imageView] setImage:[UIImage imageNamed:@"checkMark"]];
    ... 
}

[[cell imageView] setHidden:YES];

if (indexPath.row == selectedRow) { 
    [[cell imageView] setHidden:NO];
}

Have a integer variable named selectedRow and in your didSelectRowAtIndexPath delegate method include the following code,

...
selectedRow = indexPath.row;
[self.tableView reloadData];

Make sure you initialize ,

selectedRow = -1;

in init method or somewhere where it will be initialized before the table view loads.

You might want to look here. Or just google for accessoryView, that's what you have to set.
