禁止道具名称？

Question

任何保留类名列表吗？

我名为Event的组件出现问题 它包含在EventsList组件中。 当我尝试过滤列表时，出现此错误：

TypeError: posts..map is not a function

This error is located at:
   in UserPost(created by Connect(UserPosts))

但是当我去那里的时候，我看上去很好，一切都可以覆盖禁止代码...还有其他保留名称吗？

这是和平的代码：

class UserPosts extends Component {
    static navigatorButtons = {
        leftButtons: Platform.OS === 'ios' ?
        [
            {
                title:'Go back',
                id:'goBack'
            }
        ]
        :null
    }

    constructor(props){
        super(props);

        this.state = {
            image:'',
            posts:[],
            modal:false
        }


        if(Platform.OS === 'ios'){
            this.props.navigator.setOnNavigatorEvent((event)=>{
                if(event.id === 'goBack'){
                    this.props.navigator.dismissAllModals({
                        animationType:'slide-down'
                    })
                }
            })
        }
    }

    componentDidMount(){
        const UID = this.props.User.userData.uid;
        this.props.getUserPosts(UID);
    }

    componentWillReceiveProps(nextProps){
        if(nextProps.User.userPosts){
            this.setState({
                posts: nextProps.User.userPosts
            })
        }
    }

    showConfirm = (ID) => {
        this.setState({
            modal:true,
            toDelete:ID
        })
    }

    deletePost = (ID) => {
        this.props.deleteUserpost(ID,this.props.User.userData).then(()=>{
            const UID = this.props.User.userData.uid;
            this.props.getUserPosts(UID);

            this.setState({
                modal:false,
                toDelete:''
            });
        })
    }

我已经检查了代码，因为当我消除该错误时，该按钮不起作用，它可以运行，但是返回按钮不起作用。

    showPosts = (posts) => (
        posts ?
            posts.map( item => (
                <View style={styles.itemWrapper} key={item.id}>
                    <View>
                        <Image
                            source={{uri:this.state.itemImage}}
                            style={{width:'100%',height:200}}
                        />
