React Native wrapper for PSPDFKit for iOS, Android & Windows UWP. (PDF SDK for React Native)

This wrapper requires a valid license of PSPDFKit. Licenses are per platform. You can request a trial license here.

This wrapper exposes the most often used APIs from PSPDFKit. Many of our partners end up forking this wrapper and adding some custom code to achieve even greater integration with their products, using native code.

Windows is not currently supported, please use the previous version 1.24.9 instead.

iOS

Requirements

Xcode 11.5
PSPDFKit 9.5.0 for iOS or later
react-native >= 0.62.2
CocoaPods >= 1.9.3

Getting Started

Let's create a simple app that integrates PSPDFKit and uses the react-native-pspdfkit module.

Make sure react-native-cli is installed: yarn global add react-native-cli
Create the app with react-native init YourApp
Step into your newly created app folder: cd YourApp
Install react-native-pspdfkit from GitHub: yarn add github:PSPDFKit/react-native
Install all the dependencies for the project: yarn install. (Because of a bug you may need to clean yarn's cache with yarn cache clean before.)
Open ios/Podile in a text editor: open ios/Podfile, update the platform to iOS 12, and add the PSPDFKit podspecs:

- platform :ios, '9.0'
+ platform :ios, '12.0'
require_relative '../node_modules/@react-native-community/cli-platform-ios/native_modules'

target 'YourApp' do
  # Pods for YourApp
  pod 'React', :path => '../node_modules/react-native/'
  pod 'React-Core', :path => '../node_modules/react-native/React'
  pod 'React-DevSupport', :path => '../node_modules/react-native/React'
  pod 'React-fishhook', :path => '../node_modules/react-native/Libraries/fishhook'
  pod 'React-RCTActionSheet', :path => '../node_modules/react-native/Libraries/ActionSheetIOS'
  pod 'React-RCTAnimation', :path => '../node_modules/react-native/Libraries/NativeAnimation'
  pod 'React-RCTBlob', :path => '../node_modules/react-native/Libraries/Blob'
  pod 'React-RCTImage', :path => '../node_modules/react-native/Libraries/Image'
  pod 'React-RCTLinking', :path => '../node_modules/react-native/Libraries/LinkingIOS'
  pod 'React-RCTNetwork', :path => '../node_modules/react-native/Libraries/Network'
  pod 'React-RCTSettings', :path => '../node_modules/react-native/Libraries/Settings'
  pod 'React-RCTText', :path => '../node_modules/react-native/Libraries/Text'
  pod 'React-RCTVibration', :path => '../node_modules/react-native/Libraries/Vibration'
  pod 'React-RCTWebSocket', :path => '../node_modules/react-native/Libraries/WebSocket'

  pod 'React-cxxreact', :path => '../node_modules/react-native/ReactCommon/cxxreact'
  pod 'React-jsi', :path => '../node_modules/react-native/ReactCommon/jsi'
  pod 'React-jsiexecutor', :path => '../node_modules/react-native/ReactCommon/jsiexecutor'
  pod 'React-jsinspector', :path => '../node_modules/react-native/ReactCommon/jsinspector'
  pod 'yoga', :path => '../node_modules/react-native/ReactCommon/yoga'

  pod 'DoubleConversion', :podspec => '../node_modules/react-native/third-party-podspecs/DoubleConversion.podspec'
  pod 'glog', :podspec => '../node_modules/react-native/third-party-podspecs/glog.podspec'
  pod 'Folly', :podspec => '../node_modules/react-native/third-party-podspecs/Folly.podspec'

+ pod 'react-native-pspdfkit', :path => '../node_modules/react-native-pspdfkit/react-native-pspdfkit.podspec'
+ pod 'PSPDFKit', podspec: 'https://customers.pspdfkit.com/pspdfkit-ios/latest.podspec'

  use_native_modules!
end

cd ios then run pod install.
Open YourApp.xcworkspace in Xcode: open YourApp.xcworkspace.
Make sure the deployment target is set to 12.0 or higher:
Change "View controller-based status bar appearance" to YES in Info.plist:
If your application is targeting iOS versions prior to iOS 12.2 and your application does not already contain any Swift code, then you need to make sure Xcode bundles Swift standard libraries with your application distribution. To to so, open your target Build Settings and enable Always Embed Swift Standard Libraries:
Add a PDF by drag and dropping it into your Xcode project (Select "Create groups" and add to target "YourApp"). This will add the document to the "Copy Bundle Resources" build phase:
Replace the default component from App.js with a simple touch area to present the bundled PDF. (Note that you can also use a Native UI Component to show a PDF.)

import React, { Component } from "react";
import {
  AppRegistry,
  StyleSheet,
  NativeModules,
  Text,
  TouchableHighlight,
  View
} from "react-native";

const PSPDFKit = NativeModules.PSPDFKit;

PSPDFKit.setLicenseKey("INSERT_YOUR_LICENSE_KEY_HERE");

// Change 'YourApp' to your app's name.
export default class YourApp extends Component<Props> {
  _onPressButton() {
    PSPDFKit.present("document.pdf", {});
  }

  render() {
    return (
      <View style={styles.container}>
        <TouchableHighlight onPress={this._onPressButton}>
          <Text style={styles.text}>Tap to Open Document</Text>
        </TouchableHighlight>
      </View>
    );
  }
}

const styles = StyleSheet.create({
  container: {
    flex: 1,
    justifyContent: "center",
    alignItems: "center",
    backgroundColor: "#F5FCFF"
  },
  text: {
    fontSize: 20,
    textAlign: "center",
    margin: 10
  }
});

// Change both 'YourApp's to your app's name.
AppRegistry.registerComponent("YourApp", () => YourApp);

Your app is now ready to launch. Run the app in Xcode or go back to the Terminal, then run cd .., and react-native run-ios.

Usage

There are 2 different ways on how to use the PSPDFKit React Native wrapper on iOS.

Present a document via a Native Module modally.
Show a PSPDFKit view via a Native UI component.

Depending on your needs you might want to use one or the other.

Native Module

Using the Native Module (PSPDFKit.present()), you can present a document with PSPDFKit modally in fullscreen. You can specify the path to the document you want to present, and configuration options.

import React, { Component } from "react";
import { NativeModules, Text, TouchableHighlight, View } from "react-native";

var PSPDFKit = NativeModules.PSPDFKit;
PSPDFKit.setLicenseKey("YOUR_LICENSE_KEY_GOES_HERE");

export default class App extends Component<{}> {
  _onPressButton() {
    PSPDFKit.present("document.pdf", {
      pageTransition: "scrollContinuous",
      scrollDirection: "vertical",
      documentLabelEnabled: true
    });
  }

  render() {
    return (
      <View style={styles.container}>
        <TouchableHighlight onPress={this._onPressButton}>
          <Text style={styles.text}>Tap to Open Document</Text>
        </TouchableHighlight>
      </View>
    );
  }
}

Native UI Component

With PSPDFKitView you can use PSPDFKit like any other React component in your app. Using this approach, you have more flexibility over how a document is presented and displayed.

The layout is completely flexible, and can be adjust with flexbox. Note that you still need to set your license key with the Native Module.

For all the props that you can pass to PSPDFKitView, have a look at the source documentation.

This is how you would show a PDF as a React component:

import React, { Component } from "react";
import { NativeModules } from "react-native";
import PSPDFKitView from "react-native-pspdfkit";

var PSPDFKit = NativeModules.PSPDFKit;
PSPDFKit.setLicenseKey("YOUR_LICENSE_KEY_GOES_HERE");

export default class App extends Component<{}> {
  render() {
    return (
      <PSPDFKitView
        document={"document.pdf"}
        configuration={{
          pageTransition: "scrollContinuous",
          scrollDirection: "vertical",
          documentLabelEnabled: true
        }}
        style={{ flex: 1, color: "#267AD4" }}
      />
    );
  }
}

Configuration

You can configure the presentation with a configuration dictionary which is a mirror of the PSPDFConfiguration class.

Example - Native Module:

PSPDFKit.present("document.pdf", {
  thumbnailBarMode: "scrollable",
  pageTransition: "scrollContinuous",
  scrollDirection: "vertical"
});

Example - Native UI Component:

<PSPDFKitView
  document={"document.pdf"}
  configuration={{
    thumbnailBarMode: "scrollable",
    pageTransition: "scrollContinuous",
    scrollDirection: "vertical"
  }}
/>

Running Catalog Project

Copy PSPDFKit.xcframework and PSPDFKitUI.xcframework into the PSPDFKit directory.
Install dependencies: yarn install in samples/Catalog directory. (Because of a bug you may need to clean yarn's cache with yarn cache clean before.)
Run the app with react-native-cli: react-native run-ios
If you get an error about config.h not being found check out this blog post for information on how to fix it.

Running the Native Catalog

Take a look at the instructions to get started here.

Running on Mac Catalyst

Using PSPDFKit React Native Wrapper on Mac Catalyst does not currently work due to a Flipper and FlipperKit issue.

If you wish to run your project on Mac Catalyst, please try the following workaround which removes everything related to Flipper and FlipperKit.

Configuration Mapping

The PSPDFKit React Native iOS Wrapper maps most configuration options available in PSPDFConfiguration from JSON. Please refer to RCTConvert+PSPDFConfiguration.m for the complete list and for the exact naming of enum values.

Annotations are mapped based on their type name. This is case sensitive. For example, to limit annotation types to ink and highlight, use this:

editableAnnotationTypes: ["Ink", "Highlight"];

Menu Item Mapping

The PSPDFKit React Native iOS Wrapper allows you to specify a custom grouping for the annotation creation toolbar. Please refer to RCTConvert+PSPDFAnnotationToolbarConfiguration.m for the complete list of menu items. To set them just specify the menuItemGrouping prop on the PSPDFKitView. The format used is as follows:

[
  menuItem,
  { key: menuItem, items: [subItem, subItem]},
  ...
]

Customize the Toolbar Buttons

You can customize the toolbar buttons on the Native UI View component by specifying the toolbar buttons using setLeftBarButtonItems and setRightBarButtonItems, like so:

pdfView.setRightBarButtonItems(
  ["thumbnailsButtonItem", "searchButtonItem", "annotationButtonItem"],
  "document",
  false
);

Please refer to RCTConvert+UIBarButtonItem.m for the complete list of bar button items.

Also, please take a look at the ToolbarCustomization example from our Catalog app.

For a more detailed description of toolbar customizations, refer to our Customizing the Toolbar guide for iOS and Android.

Process Annotations

The PSPDFKit React Native Wrapper allows you to create a new document with processed (embedded, flattenned, removed, or printed) annotations on Android and iOS using the PSPDFKit.processAnnotations(annotationChange, annotationType, sourceDocumentPath, processedDocumentPath) function. In the snippet below, we add a button which flattens all the annotations of the document from the currently displayed PSPDFKitView in a newly processed PDF file:

<View>
  <Button
    onPress={async () => {
      const processedDocumentPath =
        RNFS.DocumentDirectoryPath + "/flattened.pdf";
      // Delete the processed document if it already exists.
      RNFS.exists(processedDocumentPath)
        .then(exists => {
          if (exists) {
            RNFS.unlink(processedDocumentPath);
          }
        })
        .then(() => {
          // First, save all annotations in the current document.
          this.refs.pdfView.saveCurrentDocument().then(success => {
            if (success) {
              // Then, flatten all the annotations
              PSPDFKit.processAnnotations(
                "flatten",
                "all",
                sourceDocumentPath,
                processedDocumentPath
              )
                .then(success => {
                  if (success) {
                    // And finally, present the newly processed document with flattened annotations.
                    PSPDFKit.present(processedDocumentPath, {});
                  } else {
                    alert("Failed to embed annotations.");
                  }
                })
                .catch(error => {
                  alert(JSON.stringify(error));
                });
            } else {
              alert("Failed to save current document.");
            }
          });
        });
    }}
    title="Flatten All Annotations"
  />
</View>

For a runnable example, please take a look at the AnnotationProcessing example from our Catalog app.

Android

Requirements

Android SDK
Android Build Tools 23.0.1 (React Native)
Android Build Tools 28.0.3 (PSPDFKit module)
Android Gradle plugin >= 3.4.1
PSPDFKit >= 5.4.2
react-native >= 0.60.4

Getting Started

Let's create a simple app that integrates PSPDFKit and uses the react-native-pspdfkit module.

Make sure react-native-cli is installed: yarn global add react-native-cli
Create the app with react-native init YourApp.
Step into your newly created app folder: cd YourApp.
Add react-native-pspdfkit module from GitHub: yarn add github:PSPDFKit/react-native.
Install all the dependencies for the project: yarn install. (Because of a bug you may need to clean yarn's cache with yarn cache clean before.)
PSPDFKit targets modern platforms, so you'll have to set the minSdkVersion to 19. In YourApp/android/build.gradle:

...
 buildscript {
     ext {
         buildToolsVersion = "28.0.3"
-        minSdkVersion = 16
+        minSdkVersion = 19
         compileSdkVersion = 28
         targetSdkVersion = 28
         supportLibVersion = "28.0.0"
...

We will also need to enable MultiDex support. In YourApp/android/app/build.gradle:

...
  defaultConfig {
      applicationId "com.yourapp"
      minSdkVersion rootProject.ext.minSdkVersion
      targetSdkVersion rootProject.ext.targetSdkVersion
      versionCode 1
      versionName "1.0"
+     multiDexEnabled true
  }
...

Enter your PSPDFKit license key into YourApp/android/app/src/main/AndroidManifest.xml file:

   <application>
      ...

+      <meta-data
+          android:name="pspdfkit_license_key"
+          android:value="YOUR_LICENSE_KEY_GOES_HERE"/>

   </application>

Set primary color. In YourApp/android/app/src/main/res/values/styles.xml replace

<!-- Customize your theme here. -->

with

<item name="colorPrimary">#3C97C9</item>

Replace the default component from YourApp/App.js with a simple touch area to present a PDF document from the local device filesystem:

import React, { Component } from "react";
import {
  StyleSheet,
  NativeModules,
  Text,
  TouchableOpacity,
  View,
  PermissionsAndroid
} from "react-native";

var PSPDFKit = NativeModules.PSPDFKit;

const DOCUMENT = "file:///sdcard/document.pdf";
const CONFIGURATION = {
  scrollContinuously: false,
  showPageNumberOverlay: true,
  pageScrollDirection: "vertical"
};

// Change 'YourApp' to your app's name.
export default class YourApp extends Component<{}> {
  _onPressButton() {
    requestExternalStoragePermission();
  }

  render() {
    return (
      <View style={styles.container}>
        <Text>{PSPDFKit.versionString}</Text>
        <TouchableOpacity onPress={this._onPressButton}>
          <Text style={styles.text}>Tap to Open Document</Text>
        </TouchableOpacity>
      </View>
    );
  }
}

async function requestExternalStoragePermission() {
  try {
    const granted = await PermissionsAndroid.request(
      PermissionsAndroid.PERMISSIONS.WRITE_EXTERNAL_STORAGE
    );
    if (granted === PermissionsAndroid.RESULTS.GRANTED) {
      console.log("Write external storage permission granted");
      PSPDFKit.present(DOCUMENT, CONFIGURATION);
    } else {
      console.log("Write external storage permission denied");
    }
  } catch (err) {
    console.warn(err);
  }
}

const styles = StyleSheet.create({
  container: {
    flex: 1,
    justifyContent: "center",
    alignItems: "center",
    backgroundColor: "#F5FCFF"
  },
  text: {
    fontSize: 20,
    textAlign: "center",
    margin: 10
  }
});

Before launching the app you need to copy a PDF document onto your development device or emulator.
```
adb push /path/to/your/document.pdf /sdcard/document.pdf
```
Your app is now ready to launch. From YourApp directory run react-native run-android.
```
react-native run-android
```

Running Catalog Project

Clone the repository. git clone https://github.com/PSPDFKit/react-native.git.
Install dependencies: run yarn install from samples/Catalog directory. (Because of a bug you may need to clean yarn's cache with yarn cache clean before.)
Update license key in samples/Catalog/android/app/src/main/AndroidManifest.xml:

   <application>
      ...

      <meta-data
          android:name="pspdfkit_license_key"
          android:value="YOUR_LICENSE_KEY_GOES_HERE"/>

   </application>

Catalog app is now ready to launch. From samples/Catalog directory run react-native run-android.

Running the Native Catalog

Take a look at the instructions to get started here.

Configuration

Upload PDF to device

To copy a pdf document to your local device storage:

adb push "document.pdf" "/sdcard/document.pdf"

Bundle PDF inside the APK's assets

To bundle a pdf document in the Android app, simply copy it the Android assets folder, for the Catalog app is samples/PDFs.

Viewer options

You can configure the builder with a dictionary representation of the PSPDFConfiguration object. Check ConfigurationAdapter.java for all the parameters available.

const CONFIGURATION = {
  startPage: 3,
  scrollContinuously: false,
  showPageNumberOverlay: true,
  grayScale: true,
  showPageLabels: false,
  pageScrollDirection: "vertical"
};

Native UI Component

Just like on iOS we also support integrating PSPDFKit directly into the react-native view hierarchy. There are a few thing you need to consider when using this approach:

Your activity hosting the react component needs to extend from ReactFragmentActivity.
Because of issues in react-native our PdfView needs to call layout and dispatchOnGlobalLayout on every frame, this might negatively affect your apps performance or even cause it to misbehave.
PSPDFKitView doesn't yet support all the features (outline, bookmarks, thubmnail grid, view settings) using PSPDFKit.present provides.

Menu Item Mapping

The PSPDFKit React Native Android Wrapper allows you to specify a custom grouping for the annotation creation toolbar. Please refer to ReactGroupingRule.java for the complete list of menu items. To set them just specify the menuItemGrouping prop on the PSPDFKitView. The format used is as follows:

[
  menuItem,
  { key: menuItem, items: [subItem, subItem]},
  ...
]

Update

Upgrading yarn's lock file is required in order to update react-native-pspdfkit module in a project that has been already setup following the steps in Getting Started section.
From root project folder (e.g.YourApp for upgrading example project) launch yarn upgrade.

Migrate from PSPDFKit version 2.9.x to 3.0.0

After launching yarn upgrade, apply step 7, step 10 and step 12 from Getting Started section.
Enable MultiDex in YourApp/android/app/build.gradle (note one place to edit):

...
android {
    compileSdkVersion 25
    buildToolsVersion "25.0.2"

defaultConfig {
    applicationId "com.yourapp"
+   multiDexEnabled true
    minSdkVersion 16
    targetSdkVersion 25
    versionCode 1
    versionName "1.0"
    ndk {
        abiFilters "armeabi-v7a", "x86"
    }
}
...

Remove pspdfkit-lib folder in YourApp/android/.
In YourApp/android/settings.gradle remove the old reference to pspdfkit-lib (note one place to edit):

 project(':react-native-pspdfkit').projectDir = new File(rootProject.projectDir, '../node_modules/react-native-pspdfkit/android')
 include ':app'
-include ':pspdfkit-lib'

Migrate from PSPDFKit version 3.3.3 to 4.0.x

After launching yarn upgrade, apply step 6, step 8 and step 10 from Getting Started section.
Enable MultiDex in YourApp/android/app/build.gradle (note four place to edit):

...
android {
-   compileSdkVersion 25
+   compileSdkVersion 26
-   buildToolsVersion "25.0.2"
+   buildToolsVersion "26.0.1"

defaultConfig {
    applicationId "com.yourapp"
    multiDexEnabled true
-   minSdkVersion 16
+   minSdkVersion 19
-   targetSdkVersion 25
+   targetSdkVersion 26
    versionCode 1
    versionName "1.0"
    ndk {
        abiFilters "armeabi-v7a", "x86"
    }
}
...
