    <content type="html"><![CDATA[<h3>一、注释</h3>

<p><strong>注释</strong>：用来说明在某段代码的作用，也可以用来说明某个类、某个方法的作用等等。</p>

<p>OC 里边有<strong>两种</strong>注释方式：单行注释，多行注释。</p>

<p><strong>单行注释</strong>：使用<code>//</code>双斜杠来表示，它只能够注释一行代码。</p>

<p><strong>多行注释</strong>：使用<code>/* ... */</code>来表示，其中<code>/*</code>这个表示开始，而 <code>*/</code>表示结束。多行注释也是说，可以将多行代码注释掉。<font color=red>特别需要注意的是：多行注释不能够嵌套。</font></p>

<blockquote><p>注释除了能够进行对代码的说明，它还能够帮助我们调试程序，当我们觉得某一句代码，或者某一块代码有问题的话，可以使用注释进行注释，在运行程序来查找相关问题。</p></blockquote>
