Expo GlassEffect

使用 iOS 原生 UIVisualEffectView 渲染液态玻璃效果的 React 组件。

iOS

tvOS

Included in Expo Go

GitHub

npm

更新日志

Bundled version:

~0.1.8

重要 GlassView 仅在 iOS 26 及以上版本可用。在不受支持的平台上，它将回退为普通 View。

使用 UIVisualEffectView 渲染原生 iOS 液态玻璃效果的 React 组件。支持可自定义的玻璃样式和色调颜色。

已知问题

isInteractive 属性只能在挂载时设置一次，在组件渲染后无法动态更改。如果你需要切换交互行为，必须使用不同的 key 重新挂载组件。
避免在 GlassView 或其父视图上使用小于 1 的 opacity 值，因为这会导致效果渲染不正确。请改用 glassEffectStyle 中的 animate 和 animationDuration 属性来淡入/淡出效果。更多信息请参见 Apple 的文档和 GitHub issue #41024。

安装

Terminal

- npx expo install expo-glass-effect

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

用法

`GlassView`

GlassView 组件用于渲染原生 iOS 玻璃效果。它支持不同的玻璃效果样式，并且可以针对各种审美需求通过色调颜色进行自定义。

Basic GlassView usage

import { StyleSheet, View, Image } from 'react-native';
import { GlassView } from 'expo-glass-effect';

export default function App() {
  return (
    <View style={styles.container}>
      <Image
        style={styles.backgroundImage}
        source={{
          uri: 'https://images.unsplash.com/photo-1506905925346-21bda4d32df4?w=400&h=400&fit=crop',
        }}
      />

      {/* 基础玻璃视图 */}
      <GlassView style={styles.glassView} />

      {/* 具有透明样式的玻璃视图 */}
      <GlassView style={styles.tintedGlassView} glassEffectStyle="clear" />
    </View>
  );
}

const styles = StyleSheet.create({
  container: {
    flex: 1,
  },
  backgroundImage: {
    ...StyleSheet.absoluteFill,
    width: '100%',
    height: '100%',
  },
  glassView: {
    position: 'absolute',
    top: 100,
    left: 50,
    width: 200,
    height: 100,
    borderRadius: 12,
    justifyContent: 'center',
    alignItems: 'center',
    padding: 20,
  },
  tintedGlassView: {
    position: 'absolute',
    top: 250,
    left: 50,
    width: 200,
    height: 100,
    borderRadius: 12,
    justifyContent: 'center',
    alignItems: 'center',
    padding: 20,
  },
  text: {
    fontSize: 16,
    fontWeight: '600',
    color: '#000',
    textAlign: 'center',
  },
});

`GlassContainer`

GlassContainer 组件允许你将多个玻璃视图组合为一个整体效果。

GlassContainer example

import { StyleSheet, View, Image } from 'react-native';
import { GlassView, GlassContainer } from 'expo-glass-effect';

export default function GlassContainerDemo() {
  return (
    <View style={styles.container}>
      <Image
        style={styles.backgroundImage}
        source={{
          uri: 'https://images.unsplash.com/photo-1547036967-23d11aacaee0?w=400&h=600&fit=crop',
        }}
      />
      <GlassContainer spacing={10} style={styles.containerStyle}>
        <GlassView style={styles.glass1} isInteractive />
        <GlassView style={styles.glass2} />
        <GlassView style={styles.glass3} />
      </GlassContainer>
    </View>
  );
}

const styles = StyleSheet.create({
  container: {
    flex: 1,
  },
  backgroundImage: {
    ...StyleSheet.absoluteFillObject,
    width: '100%',
    height: '100%',
  },
  containerStyle: {
    position: 'absolute',
    top: 200,
    left: 50,
    width: 250,
    height: 100,
    flexDirection: 'row',
    alignItems: 'center',
    gap: 5,
  },
  glass1: {
    width: 60,
    height: 60,
    borderRadius: 30,
  },
  glass2: {
    width: 50,
    height: 50,
    borderRadius: 25,
  },
  glass3: {
    width: 40,
    height: 40,
    borderRadius: 20,
  },
});

`isLiquidGlassAvailable`

isLiquidGlassAvailable 函数可以让你检查编译后的应用中是否可用 Liquid Glass 效果。它会验证系统和编译器版本，以及 Info.plist 设置。

import { isLiquidGlassAvailable } from 'expo-glass-effect';

export default function CheckLiquidGlass() {
  return (
    <Text>
      {isLiquidGlassAvailable()
        ? 'Liquid Glass effect is available'
        : 'Liquid Glass effect is not available'}
    </Text>
  );
}

`isGlassEffectAPIAvailable`

isGlassEffectAPIAvailable 函数用于检查设备运行时是否可用 Liquid Glass API。

警告添加此 API 的原因是某些 iOS 26 测试版中没有可用的 Liquid Glass API，这可能会导致崩溃。在应用中使用 GlassView 之前应先检查这一点，以确保兼容性。更多信息请参见 GitHub issue #40911。

import { isGlassEffectAPIAvailable } from 'expo-glass-effect';

export default function CheckGlassEffectAPI() {
  return (
    <Text>
      {isGlassEffectAPIAvailable()
        ? 'Glass Effect API is available'
        : 'Glass Effect API is not available'}
    </Text>
  );
}

API

import {
  GlassView,
  GlassContainer,
  isLiquidGlassAvailable,
  isGlassEffectAPIAvailable,
} from 'expo-glass-effect';
