Implement a Back Button on Navigation Bar in iPhone App
<p>Just recently took over a project from my developer. I'm a noob to coding, but can figure things out pretty well. I'm just trying to implement Back button on one of my screens. It already has the navigation Bar, but no back button, just the title. </p>

<p>Is there a guide on how to get this implemented? Any help would be great!</p>

<p>Thanks!</p>

<p>Update = Here is the code:</p>

<pre><code>&lt;object class="IBUINavigationController" id="144954994"&gt;
&lt;reference key="NSNextResponder" ref="191373211"/&gt;
&lt;int key="NSvFlags"&gt;290&lt;/int&gt;
&lt;string key="NSFrameSize"&gt;{320, 44}&lt;/string&gt;
&lt;reference key="NSSuperview" ref="191373211"/&gt;
&lt;bool key="IBUIOpaque"&gt;NO&lt;/bool&gt;
&lt;bool key="IBUIClearsContextBeforeDrawing"&gt;NO&lt;/bool&gt;
&lt;int key="IBUIBarStyle"&gt;2&lt;/int&gt;
&lt;object class="NSArray" key="IBUIItems"&gt;
&lt;bool key="EncodedWithXMLCoder"&gt;YES&lt;/bool&gt;
&lt;object class="IBUINavigationController" id="445217273"&gt;
&lt;reference key="IBUINavigationController" ref="144954994"/&gt;
&lt;string key="IBUITitle"&gt;Answer Question&lt;/string&gt;
&lt;/object&gt;
&lt;/object&gt;
&lt;/object&gt;
</code></pre>
