我正在尝试从AsyncStorage获取数据,但是它返回对象对象,我如何才能正常返回数据? 如果我在console.log()中返回数据,一切正常,但是当我调用函数时,它将返回对象对象。
谢谢
const getTheme = async () => {
try {
const value = await AsyncStorage.getItem('theme');
console.log(value); // returns dark
return JSON.stringify(value)
} catch (error) {
alert(error)
}
};
alert(getTheme()) // [object, object]
const TabNavigator = createBottomTabNavigator(
{
Home: {
screen: Home,
navigationOptions: ({ navigation }) => ({
tabBarLabel: "Home",
tabBarVisible: getActiveRoute(navigation.state) !== "ArticleScreen",
tabBarIcon: ({ tintColor }) => (
<Icon name="ios-home" color={tintColor} size={24} />
)
})
},
Courses: {
screen: Courses,
navigationOptions: {
tabBarLabel: "Courses",
tabBarIcon: ({ tintColor }) => (
<Icon name="ios-school" color={tintColor} size={24} />
)
}
}
},
{}
)
export default createAppContainer(TabNavigator);
class App extends React.Component {
render() {
return <TabNavigator />;
}
}

尝试将其分类吗?
console.log(JSON.stringify(apiRequest1));
-----根据您的新更新---- 您是否从数据中获得了黑暗(主题?)?
您可以尝试以下方法:
const getTheme = async () => {
try {
const value = await AsyncStorage.getItem('theme');
console.log(value); // returns dark (Is here a theme?)
return value //Just retrun the value of dark?
} catch (error) {
alert(error)
}
};
alert(getTheme) //Is here have to use getTheme not getTheme()?
您可以尝试。
