使用

基本的 disclosure group

BasicDisclosureGroupExample.tsx

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

export default function BasicDisclosureGroupExample() {
  return (
    <Host matchContents>
      <DisclosureGroup label="更多信息">
        <Text>当 disclosure group 展开时，会显示此内容。</Text>
      </DisclosureGroup>
    </Host>
  );
}

初始展开

将 isExpanded 初始设置为 true，即可默认显示内容。

InitiallyExpandedExample.tsx

import { useState } from 'react';
import { Host, DisclosureGroup, Text } from '@expo/ui/swift-ui';

export default function InitiallyExpandedExample() {
  const [isExpanded, setIsExpanded] = useState(true);

  return (
    <Host matchContents>
      <DisclosureGroup label="详情" isExpanded={isExpanded} onIsExpandedChange={setIsExpanded}>
        <Text>此内容默认可见。</Text>
      </DisclosureGroup>
    </Host>
  );
}
