我制作了一个登录控制器组件,然后将stackNavigator传递给它,我的问题是我应该将jwt令牌传递给屏幕,但是我无法访问“ this.state.jwt”
我知道有一些熟悉的问题,但是我无法将答案笼罩在脑海中。
export default class App extends Component {
constructor() {
super();
this.state = {
jwt: '',
loading: true
}
this.newJWT = this.newJWT.bind(this);
this.deleteJWT = deviceStorage.deleteJWT.bind(this);
this.loadJWT = deviceStorage.loadJWT.bind(this);
this.loadJWT();
}
newJWT(jwt){
this.setState({
jwt: jwt
});
}
render() {
if (this.state.loading) {
this.deleteJWT()
return (
<Loading size={'large'} />
);
} else if (!this.state.jwt) {
return (
<Auth newJWT={this.newJWT} />
);
} else if (this.state.jwt) {
return (
<RootNav screenProps={this.state.jwt} />
);
}
}
}
const BottomNaviagtor = createBottomTabNavigator ({
Home: Home,
Top: Top,
Following: {screen: Following},
LikeD: {screen:Liked}
})
const RootNav = createAppContainer(BottomNaviagtor)
我应该这样做:Home jwt = {this.state.jw}并针对所有其他bottomNavigator屏幕执行此操作
答案 0 :(得分:0)
抱歉,评论不足,如果您将screenProps修改为
,我认为您将其作为screenProp传递screenProps = {{ jwt:this.state.jwt}}
您是否可以在屏幕上执行this.props.screenProps.jwt?
