React Native 防截屏库,阻止并检测截图、录屏和后台预览,兼顾 Expo 与 CLI

React Native 防截屏与录屏检测库,可拦截并识别截图、屏幕录制和应用切换,兼容 Expo 与 CLI,用于提升移动端隐私安全。

核心能力

  • 阻止 iOS 与 Android 的截图和录屏
  • iOS 额外支持 App Switcher 预览遮挡
  • 提供事件监听与 useCaptureProtection Hook
  • 可按截图、录屏、后台预览分别开关
  • 内置 Jest mock 便于单元测试

容易踩的坑

Expo 仅支持 Dev Client,Expo Go 无法使用;React Native 低于 0.70 需改用 v1.9.17;Android 需在 build.gradle 配置 missingDimensionStrategy,低于 14 的截图检测需改用 callbackTiramisu 并声明 READ_MEDIA_IMAGES

    ✨ Features

    • 🔒 iOS: Screenshot, Screen Recording & App Switcher protection
    • 🔒 Android: Screenshot & Screen Recording protection
    • 📡 Event listeners for capture events
    • 🧩 Hooks & Provider support
    • 📱 Android 14 support

    🚀 Installation

    ⚠️ Using React Native < 0.70?
    The latest v2.x version may not be compatible with versions below 0.70.
    It is recommended to use v1.9.17 for better stability with older React Native projects.

    Using npm

    npm install react-native-capture-protection
    

    Using yarn

    yarn add react-native-capture-protection
    

    Using with Expo

    ⚠️ Expo Dev Client only This library includes native code, so it does not work with Expo Go. You must use a custom dev client.

    npx expo install react-native-capture-protection
    

    🔧 iOS Setup

    If you're developing for iOS, don't forget to install CocoaPods dependencies after installing the package.

    cd ios && pod install
    

    ⚙️ Android Configuration (Required)

    By default, it supports capture prevention, capture permission, and capture detection on Android 14 and above. On Android versions below 14 (Android 10-13), capture prevention and capture permission are supported by default; if you want capture detection support too, please refer to the Capture Detection Before Android 14 (Optional) below.

    React Native CLI

    add to android/app/build.gradle

    defaultConfig {
        ...
        missingDimensionStrategy "react-native-capture-protection", "base"
    }
    

    Expo (Dev Client only)

    add to app.json

    {
      ...
      "plugins": [
        ...,
        [
          "react-native-capture-protection",
          {
            "captureType": "base"
          }
        ]
      ]
    }
    

    Capture Detection Before Android 14 (Optional)

    On Android versions below 14 (Android 10-13), capture prevention and capture permission are supported by default and require no more steps. However, if you want capture detection to work on Android versions below 14, please configure the settings as follows (it detects screen captures using the sensitive READ_MEDIA_IMAGES permission):

    Google Play Store Policy (READ_MEDIA_IMAGES)

    If publishing to the Play Store, explain the usage of READ_MEDIA_IMAGES like this:

    Used by the application to detect screenshots, by checking for screenshot files in the user’s media storage.
    

    React Native CLI

    add to android/app/build.gradle

    defaultConfig {
        ...
        missingDimensionStrategy "react-native-capture-protection", "callbackTiramisu"
    }
    

    Expo (Dev Client only)

    add to app.json

    {
      ...
      "plugins": [
        ...,
        [
          "react-native-capture-protection",
          {
            "captureType": "callbackTiramisu"
          }
        ]
      ]
    }
    

    📦 Usage

    import {
      CaptureProtection,
      useCaptureProtection,
      CaptureEventType
    } from 'react-native-capture-protection';
    
    const Component = () => {
      const { protectionStatus, status } = useCaptureProtection();
    
      React.useEffect(() => {
        // Prevent all capture events
        CaptureProtection.prevent();
    
        // Or prevent specific events
        CaptureProtection.prevent({
          screenshot: true,
          record: true,
          appSwitcher: true
        });
      }, []);
    
      React.useEffect(() => {
        // Check if any capture is prevented
        console.log('Prevent Status:', protectionStatus);
    
        // Check current protection status
        console.log('Protection Status:', status);
      }, [protectionStatus, status]);
    
      // Allow all capture events
      const onAllow = async () => {
        await CaptureProtection.allow();
      };
    
      // Allow specific events
      const onAllowSpecific = async () => {
        await CaptureProtection.allow({
          screenshot: true,
          record: false,
          appSwitcher: true
        });
      };
    
      // Check if screen is being recorded
      const checkRecording = async () => {
        const isRecording = await CaptureProtection.isScreenRecording();
        console.log('Is Recording:', isRecording);
      };
    
      return (
        // Your component JSX
      );
    };
    

    Jest integration

    With Jest Setup

    1. Add to your jest.config.js:
    module.exports = {
      setupFilesAfterEnv: ['<rootDir>/jest.setup.js'],
    };
    
    1. Create jest.setup.js:
    jest.mock('react-native-capture-protection', () =>
      require('react-native-capture-protection/jest/capture-protection-mock')
    );
    

    Overriding mock

    import { CaptureProtection } from "react-native-capture-protection/jest/capture-protection-mock";
    
    ...
    
        test("prevent is called", async () => {
            await CaptureProtection.prevent();
            expect(CaptureProtection.prevent).toHaveBeenCalled();
        });
