how to display the go back style UIBarButtonItem programmatically
<p>When One of my app nagivate from one controller ti another, the 'go back'              UIBarButtonItem disappear, so I wrote codes:</p>

<pre><code>        UIBarButtonItem *barButton1 = [[UIBarButtonItem alloc] initWithTitle:@""
                                                                       style:UIBarButtonItemStyleDone
                                                                      target:self
                                                                      action:@selector(barButtonItemPressed:)];
        self.navigationItem.leftBarButtonItem = barButton1;
        [barButton1 setImage:[UIImage imageNamed:@"fdj.png"]];
        [barButton1 release];
</code></pre>
