react native 入门之错误集锦

问题1、Element type is invalid: expected a string (for built-in components) or a class/function (for composite components) but got: object.Check the render method of StartUp.instantiateReactComponent

解决办法：

一定要使用<Navigator.Navigator />, 直接使用，会报错

export default class Imooc_gp extends Component {

    render() {
        return (
            <Navigator.Navigator
                initialRoute={{component: Boy}}
                renderScene={
                    (route, navigator) => {
                        let Component = route.component;
                        return <Component navigator={navigator} {...route.params}/>
                    }
                }
            />
        )
    }
}
AppRegistry.registerComponent('imooc_gp', () => Imooc_gp);
