ios - 继承 UIActionSheet
<p><p>我想继承 <code>UIActionSheet</code> 以便我可以添加 blockAPI。 </p>
<p>我想子类化，这样我仍然可以享受操作表的“ self 保留”行为。<br/>
我更喜欢它而不是创建一个将 <code>UIActionSheet</code> 作为实例保存的对象，因为那样我将需要保存对该对象的引用，因此它不会被释放。 </p>
<p><strong>所以我的问题是，我可以继承 <code>UIActionSheet</code>(Apple 会允许吗)？</strong> </p>
<p>我只是不确定，因为我在 <code>UIActionSheet</code> 类引用中看到:</p>
<blockquote>
<p>Subclassing Notes:<br/>
UIActionSheet is not designed to be subclassed, nor
should you add views to its hierarchy. If you need to present a sheet
with more customization than provided by the UIActionSheet API, you
can create your own and present it modally with
presentViewController:animated:completion:.</p>
</blockquote></p>
<br><hr><h1><strong>Best Answer-推荐答案</ strong></h1><br>
<p><p>答案是否定的。如果您将 UIActionSheet 子类化，您的应用程序在发送到 Apple App Store 时可能会被拒绝。如果 UIActionSheet 不能满足您的需求，您需要实现自己的自定义操作表。这同样适用于 UIAlertView。</p>
<p>这显然是 <strong> <a href="https://developer.apple.com/library/ios/documentation/uikit/reference/UIActionSheet_Class/Reference/Reference.html" rel="noreferrer noopener nofollow">stated in the documentation</a> </strong>:</p>
