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.
