javascript - 将事件发送到 javascript 文档的 react native 模块是否正确？
<p><p>在 Facebook 的 <a href="http://facebook.github.io/react-native/docs/nativemodulesios.html#content" rel="noreferrer noopener nofollow">doc</a>它说</p>
<pre><code>- (void)calendarEventReminderReceived:(NSNotification *)notification
{
NSString *eventName = notification.userInfo[@"name"];
[self.bridge.eventDispatcher sendAppEventWithName:@"EventReminder"
body:@{@"name": eventName}];
}
</code></pre>
<p>JavaScript 代码可以订阅这些事件:</p>
<pre><code>var subscription = DeviceEventEmitter.addListener(
'EventReminder',
(reminder) => console.log(reminder.name)
);
</code></pre>
<p>但我永远无法完成这项工作。这应该是 sendDeviceEventWithName 吗？原生模块也应该总是单例的吗？</p></p>

<p><p>目前，没有。请看这个问题:</p>

<blockquote>
<p>Changing the example Objective-C to call sendDeviceEventWithName
instead of sendAppEventWithName fixes the problem.</p>

<p>这似乎证实了您的建议。有一个拉取请求等待合并:</p>
