React Native的模態，AsyncStorage，DeviceEventEmitter

1.模態modal

A介面

<Modal    animationType='slide'    transparent={false}    visible={this.state.isModal}    onRequestClose={() => this.onRequestClose()}>    <HalfHourHot removeModal={(data) => this.closeModal(data)}/></Modal>    constructor(props) {        super(props);        this.state = {            isModal: false,        };    };    onRequestClose() {        this.setState({            isModal: false,        });    };    closeModal(data) {        this.setState({            isModal: data,        });    };

HalfHourHot介面必須有一個removeModal屬性，且是func

    static propTypes = {        removeModal: PropTypes.func,    };    //某處操作需要返回到A介面    popToHome(data) {        //this.props.navigator.pop();        this.props.removeModal(data);    }

2.AsyncStorage—SharedPreferences

A介面

    componentDidMount() {        this.listener = DeviceEventEmitter.addListener('listen', (value) => {            console.log(value.num);        });    };    componentWillUnmount() {        this.listener.remove('listen');    };

B介面發送

DeviceEventEmitter.emit('listen', {num: 12});
