＃react-native - Onesignal implementation

Question

我得到this.handleNotification（）/ this.setState（）不是一個函數在內部使用onReceived（通知）{}，onOpened（openResult）時發生錯誤{} Onesignal事件我創造了。下面是我的代碼。 任何解決方案。我正在實施或不正確？

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('', '', '');  
    }

你必須結合上下文如下代碼：

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