React Native Firebase iOS onNotification不会触发

Question

我的项目正在导入“ react-native-firebase”，我正在尝试使用设备令牌通过Firebase控制台发送测试消息。方法firebase.notifications（）。onNotification（（notification）=> {}）在android设备上触发，但在ios设备上不触发。 通知不会同时在前台和后台弹出。我已经在该方法中尝试过“ console.log”，但未显示任何内容。请让我知道问题出在哪里。 我尝试了“ onMessage（）”，但它仅在前台触发。

这是我的代码：

if (Platform.OS == 'android') {
            this.notificationListener = firebase.notifications().onNotification((notification: Notification) => {
                console.log("onNotification");
                console.log(notification);
                notification
                    .setSound("default")
                    .android.setChannelId('default')
                    .android.setBigText(notification.body, notification.title, '')
                //     .android.setSmallIcon('@mipmap/icon_noti');
                firebase.notifications().displayNotification(notification);
            });
        }
        else {
            this.notificationListener = firebase.notifications().onNotification((notification) => {
                notification.setNotificationId(notification.messageId)
                notification.setSound("default"); 
                notification.setTitle(notification.data.title)
                notification.ios.setBadge(notification.ios.badge ? notification.ios.badge + 1 : 0);
                firebase.notifications().displayNotification(notification);
            });
