＃react-native - Onesignal实现

Question

我在使用内部onReceived（通知）{}，onOpened（openResult）{} Onesignal事件时得到 this.handleNotification（）/ this.setState（）不是函数错误创建。下面是我的代码。 任何解决方案。我是否正确实施？

componentWillMount() {    
    OneSignal.addEventListener('received', this.onReceived);
    OneSignal.addEventListener('opened', this.onOpened);   
}
componentWillUnmount() {
    OneSignal.removeEventListener('received', this.onReceived);
    OneSignal.removeEventListener('opened', this.onOpened);
}  

onOpened(openResult) {
    try {      
      this.setState({ msgBody: openResult.notification.payload.body });   
    } catch (error) { }
  }
  onReceived(notification) {
     OBJ.homeData.setNewMsgCount();     
     this.handleNotification('', '', '');     
  }

您必须将上下文绑定为以下代码：

OneSignal.addEventListener('received', this.onReceived.bind(this));
