react-native - React Native : Why does stylesheet. 创建带有数字而不是样式的返回对象？

Question

我创建了样式，但有时我无法使用它们，因为它们返回数字:

const styles = StyleSheet.create({
    container: {
        flex: 1,
        backgroundColor: '#FFFFFF'
    },
    moodSliderContainer: {
        justifyContent: 'center',
        alignItems: 'center',
        width: '100%'
    },
    postListContainer: {
        width: '100%',
        height: '100%',
        paddingBottom: 120
    }
});
console.log(styles);

来自 React Native documentation - StyleSheet :

Performance:

• Making a stylesheet from a style object makes it possible to refer to it by ID instead of creating a new style object every time.

• It also allows to send the style only once through the bridge. All subsequent uses are going to refer an id (not implemented yet).

如果要检索实际样式对象，可以使用 StyleSheet.flatten(styles.container) .
