ios - "unrecognized selector sent to instance"属性 setter
<p><p>我有一个继承自 <code>UILocalNotification</code> 的自定义类，它有一个 <code>Store</code> 对象属性(继承自 <code>NSObject</code> 的类):</p>
<p><strong>customLocalNotification.h</strong>:</p>
<p><code>@property (strong,nonatomic) 存储 *store;</code></p>
<p>但是当我尝试像这样在 <code>viewController</code> 中设置“Store”对象时:</p>
<pre><code>customLocalNotification *notification=[ init];
notification.store=store; //Crashes here
</code></pre>
<p><strong>编辑</strong>:我将使用 <code>userInfo</code> 字典来保存我的 <code>Store</code> 对象，但是当我尝试这样做时，它会因此错误而崩溃留言:</p>

<p>有人知道为什么会崩溃吗？</p>
<p>谢谢!</p></p>

<p><p><code>UILocalNotifications</code> 旨在包含一些<strong>轻量级</strong>数据。也就是说，<code>userInfo</code> 可以包含 <a href="https://developer.apple.com/library/ios/documentation/General/Conceptual/DevPedia-CocoaCore/PropertyList.html#//apple_ref/doc/uid/TP40008195-CH44" rel="noreferrer noopener nofollow">property list encodable</a>仅限项目。而且我要补充一点，整个事情并不是为了扔重物而设计的，而只是传递一些上下文信息，当通知到达时您需要处理这些信息(即一些标识符、数字等)。</p></p>
