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

用法

带有 SF Symbol 的基本 Label

BasicLabelExample.tsx

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

export default function BasicLabelExample() {
  return (
    <Host style={{ flex: 1 }}>
      <Label title="Favorites" systemImage="star.fill" />
    </Host>
  );
}

使用自定义图标

使用 icon 属性提供自定义 React 节点作为图标，而不是 SF Symbol。

LabelCustomIconExample.tsx

import { Host, Label, Image } from '@expo/ui/swift-ui';

export default function LabelCustomIconExample() {
  return (
    <Host matchContents>
      <Label
        title="Custom Icon"
        icon={
          <Image systemName="sparkles" size={20} color="purple" />
        }
      />
    </Host>
  );
}

仅显示图标

使用 labelStyle 修饰符和 iconOnly 仅显示图标。出于无障碍考虑，请始终提供 title，即使它不会显示。

LabelIconOnlyExample.tsx

import { Host, Label } from '@expo/ui/swift-ui';
import { labelStyle } from '@expo/ui/swift-ui/modifiers';

export default function LabelIconOnlyExample() {
  return (
    <Host style={{ flex: 1 }}>
      <Label
        title="Settings"
        systemImage="gear"
        modifiers={[labelStyle('iconOnly')]}
      />
    </Host>
  );
}

import { Label } from '@expo/ui/swift-ui';
