亲爱的朋友们,我在简单的代码中遇到问题 当我运行代码i`给出这个错误。向我本人道歉,反应原生:)
import React, { Component } from 'react';
import {
ListView,
View
} from 'react-native';
import MyPresentationalComponent1 from './MyPresentationalComponent1'
export default class MyContainerComponent extends Component {
constructor(props) {
super(props);
const ds = new ListView.DataSource({rowHasChanged: (r1, r2) => r1 !==
r2});
this.state = {
dataSource: ds.cloneWithRows([
'Item1', 'Item2', 'Item3', 'Item4', 'Item5', 'Item6', 'Item7',
'Item8',
'Item9', 'Item10'
])
};
}
render() {
return (
<View>
<MyPresentationalComponent1 dataSource = {this.state.dataSource}/>
</View>
);
}
}`
