javascript - React native 模块向 javascript 文档发送事件是否正确？

Question

在 facebook 的 doc它说

- (void)calendarEventReminderReceived:(NSNotification *)notification
{
    NSString *eventName = notification.userInfo[@"name"];
    [self.bridge.eventDispatcher sendAppEventWithName:@"EventReminder"
                                               body:@{@"name": eventName}];
}

JavaScript 代码可以订阅这些事件:

var subscription = DeviceEventEmitter.addListener(
    'EventReminder',
    (reminder) => console.log(reminder.name)
);

但我永远无法完成这项工作。这应该改为 sendDeviceEventWithName 吗？原生模块也应该始终是单例的吗？

目前，没有。请看这个问题:

Changing the example Objective-C to call sendDeviceEventWithName instead of sendAppEventWithName fixes the problem.

这似乎证实了您的建议。有一个等待合并的拉取请求:
