Text变成0时颜色会变化，变成1不会，Android是好的

import {createElement, Component, render} from 'rax';
import {View, Text, Modal, Button, Image, TextInput, Picker,TouchableHighlight,ScrollView } from 'nuke';
class TextBug extends Component {
    constructor(props) {
      super(props);
      this.state = {
        imgUrl: null,
        num: 9
      };
    }
    componentDidMount() {
        setTimeout(()=> {
            this.setState({
                num: 0
            })
        }, 1000);
    }
    render() {
        return (
                <View style={{backgroundColor: '#ff0000'}}>
                    <Text style={{color: '#ffffff'}}>{this.state.num}</Text>
                </View>
        );
    }
}
render(<TextBug/>);
