更新日志

信息关于跨平台用法，请参见通用的 Column — 它会根据平台渲染相应的原生组件。

Expo UI VStack 与官方 SwiftUI VStack API 保持一致，并将其子元素垂直排列。

安装

Terminal

- npx expo install @expo/ui

If you are installing this in an existing React Native app, make sure to install expo in your project.

用法

基础垂直堆栈

BasicVStackExample.tsx

import { Host, VStack, Text } from '@expo/ui/swift-ui';

export default function BasicVStackExample() {
  return (
    <Host matchContents>
      <VStack spacing={12}>
        <Text>第一</Text>
        <Text>第二</Text>
        <Text>第三</Text>
      </VStack>
    </Host>
  );
}

带对齐

alignment 属性控制子元素的水平对齐方式。可用选项有：leading、center 和 trailing。

VStackAlignmentExample.tsx

import { Host, VStack, Rectangle } from '@expo/ui/swift-ui';
import { frame } from '@expo/ui/swift-ui/modifiers';

export default function VStackAlignmentExample() {
  return (
    <Host matchContents>
      <VStack spacing={12} alignment="leading">
        <Rectangle modifiers={[frame({ width: 50, height: 50 })]} />
        <Rectangle modifiers={[frame({ width: 100, height: 50 })]} />
        <Rectangle modifiers={[frame({ width: 75, height: 50 })]} />
      </VStack>
    </Host>
  );
}
