IOS上的React-native：无法在可用视图之外调整当前堆栈顶部

这是我的代码：

var Badge = require('./badge');
var Separator = require('./helpers/seperator');
var View = React.View;
var StyleSheet = React.StyleSheet;
var ScrollView = React.ScrollView;
var Text = React.Text;

var Profile = React.createClass({
    _getRowTitle: function (userInfo,item) {
        item = item.replace('_',' ');
        return item[0] ? item[0].toupperCase() + item.slice(1) : item;
    },render: function () {
        var userInfo = this.props.userInfo;
        var topicArr = ['followers','following','email','bio'];
        var list = topicArr.map((item,index) => {
                return (
                    <View key={index}>
                        <View>
                            <Text> {this._getRowTitle(userInfo,item)} </Text>
                            <Text> {userInfo[item]} </Text>
                        </View>
                        <Seperator />
                    </View>
                );
            }
        });

        return (
            <ScrollView style={styles.container}>
                <Badge userInfo={this.props.userInfo} />
                {list}
            </ScrollView>
        );
    }
});

有谁知道这个错误来自哪里？
