javascript - Error with multiple components/classes for TabBar in react-native? -

-

in react-native app, have implemented tabbar , aiming have various components (each defined in own classes) load upon selection of each tab. however, i'm getting error: "onlychild must passed children 1 child", when try select tab on tabbar.

var create = require('./create'); var feed = require('./feed');  var icon = require('react-native-vector-icons/ionicons');  var homepage = react.createclass({      render: function() {         return (             <tabbarios                 tintcolor="white"                 bartintcolor="darkslateblue">             <icon.tabbaritemios                 title="feed"                 iconname="ios-star"                 selectediconname="ios-star"                 selected={this.state.selectedtab === 'feed'}                 onpress={() => {                     this.setstate({                     selectedtab: 'feed',                     });                 }}>             </icon.tabbaritemios>             <icon.tabbaritemios                 title="create"                 selected={this.state.selectedtab === 'create'}                 iconname="ios-person"                 selectediconname="ios-person"                 onpress={() => {                     this.setstate({                         selectedtab: 'greentab',                     });                 }}>             </icon.tabbaritemios>         </tabbarios>         );     }, });

edit: including feed.js:

var react = require('react-native'); var {     stylesheet,     view,     text,     component } = react;  var styles = stylesheet.create({     description: {         fontsize: 20,         textalign: 'center',         color: '#ffffff'     } });  class feed extends component {     constructor(props) {         super(props);     }     render() {         return (             <view style={styles.container}>                 <text style={styles.description}>                     feed page!                 </text>             </view>         );     } }  module.exports = feed;

i can't determine causing error , not sure if right way go loading various components different files. insight highly appreciated.

you getting error because not providing view tabbaritemios. you have provide 1 view tabbaritemios

this how i'd implement tabbarios.

an object containing names of views-

var tabs = {     upcoming: 'upcoming',     search: 'search',     popular: 'popular',     watchlist: 'watchlist',     logout: 'logout' }

and inside render method, - 

render: function(){         _this=this;         return(                 <tabbarios translucent={true}>                     <icon.tabbaritem                         title="upcoming"                         iconname="arrow-graph-up-right"                         selectediconname="arrow-graph-up-right"                         onpress={()=>this.setstate({selectedtab: tabs.upcoming})}                         selected={this.state.selectedtab === tabs.upcoming}                     >                         {this._renderhome()}                     </icon.tabbaritem>                     <icon.tabbaritem                         title="search"                         iconname="ios-search"                         selectediconname="ios-search-strong"                         onpress={()=>this.setstate({selectedtab: tabs.search})}                         selected={this.state.selectedtab === tabs.search}                     >                         {this._rendersearch()}                     </icon.tabbaritem>                                       <icon.tabbaritem                         title="popular"                         iconname="android-star-outline"                         selectediconname="android-star"                         onpress={()=>this.setstate({selectedtab: tabs.popular})}                         selected={this.state.selectedtab === tabs.popular}                     >                         {this._renderpopular()}                     </icon.tabbaritem>                     <icon.tabbaritem                         title="watchlist"                         iconname="ios-list-outline"                         selectediconname="ios-list"                         onpress={()=>this.setstate({selectedtab: tabs.watchlist})}                         selected={this.state.selectedtab === tabs.watchlist}                     >                         {this._renderblank('your watchlist')}                     </icon.tabbaritem>                     <icon.tabbaritem                         title="logout"                         iconname="log-out"                         selectediconname="log-out"                         onpress={this._logout}                         selected={this.state.selectedtab === tabs.logout}                     >                     </icon.tabbaritem>                                   </tabbarios>         )     },

and render individual views through functions one-

_renderhome: function(){     return(         <homeview navigator={this.props.navigator} />     ) },

back when new react native, had created sample app. take @ this file clear doubts.
