Prerequisites

A license is required for trial. Please contact our sales team to obtain a free trial license.
npm or yarn
ComPDFKit SDK => 2.0.1
react-native => 0.71.0
Android minSdkVersion of 21 or higher
Android targetSdkVersion of 30 or higher
iOS 12 or higher

Installation

First, please follow the official React Native environment setup guide, configure iOS and Android environments, and create a React Native project.

If you have already created a React Native project, you can skip directly to Installing the ComPDFKit Dependency.

Creating a New Project

Let's create a simple app that integrates ComPDFKit for React Native.

In the terminal app, change the current working directory to the location you wish to save your project. In this example, we’ll use the ~/Documents/ directory:
```
cd ~/Documents
```
Create the React Native project by running the following command:
```
react-native init MyApp
```
In the terminal app, change the location of the current working directory inside the newly created project:
```
cd MyApp
```

Installing-the-ComPDFKit-Dependency

You can integrate the SDK in two ways:

Through ComPDFKit GitHub repo:

In MyApp folder, install @compdfkit_pdf_sdk/react_native by calling:
```
yarn add github:ComPDFKit/compdfkit-pdf-sdk-react-native
```
Through ComPDFKit npm package:

In MyApp folder, install run the following commands:
```
yarn add @compdfkit_pdf_sdk/react_native
```

Android

open android/app/src/main/AndroidManifest.xml , add Internet Permission and Storage Permission：

<manifest xmlns:android="http://schemas.android.com/apk/res/android"
    package="com.compdfkit.flutter.example">

+    <uses-permission android:name="android.permission.INTERNET"/>

    <!-- Required to read and write documents from device storage -->
+    <uses-permission android:name="android.permission.READ_EXTERNAL_STORAGE"/>
+    <uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE"/>

		<!-- Optional settings -->
+    <uses-permission android:name="android.permission.MANAGE_EXTERNAL_STORAGE" />

    <application
+    android:requestLegacyExternalStorage="true"
        ...>
	...
    </application>
</manifest>

Copy the sample pdf file to the assets directory

Replace App.js (or App.tsx) with what is shown for Usage-Example
Finally in the root project directory, run react-native run-android.

iOS

Open your project’s Podfile in a text editor:

open ios/Podfile

Add the following line to the target 'MyApp' do ... end block:

target 'MyApp' do
    # ...
+    pod "ComPDFKit", podspec:'https://www.compdf.com/download/ios/cocoapods/xcframeworks/compdfkit/2.1.3.podspec'
+  pod "ComPDFKit_Tools", podspec:'https://www.compdf.com/download/ios/cocoapods/xcframeworks/compdfkit_tools/2.1.3.podspec'
    # ...
end

Note: If SSL network requests fail to download the ComPDFKit library when you run pod install, you can use the following method instead.

target 'MyApp' do
    # ...
+  pod 'ComPDFKit', :git => 'https://github.com/ComPDFKit/compdfkit-pdf-sdk-ios-swift.git', :tag => '2.1.3'
+  pod 'ComPDFKit_Tools', :git => 'https://github.com/ComPDFKit/compdfkit-pdf-sdk-ios-swift.git', :tag => '2.1.3'
    # ...
end

In the ios folder, run pod install.
Open your project’s Workspace in Xcode:
```
open ios/MyApp.xcworkspace
```
Make sure the deployment target is set to 10.0 or higher:
Add the PDF document you want to display to your application by dragging it into your project. On the dialog that’s displayed, select Finish to accept the default integration options. You can use "PDF_Document.pdf" as an example.

Configuration

When rendering a PDF view using the ComPDFKit.openDocument method or the CPDFReaderView UI component , you have the flexibility to enable or disable certain features or adjust default attribute values for PDF annotations, forms, and more through the CPDFConfiguration settings.

For your convenience, you can obtain default attribute values by using the ComPDFKit.getDefaultConfig({}) method.

The following example demonstrates the configuration settings for some aspects. For more detailed configuration options, refer to CONFIGURATION for further information.

Set the initial display mode and the list of available modes. The following code shows enabling only the viewer mode and annotations mode:

import { ComPDFKit, CPDFViewMode } from '@compdfkit_pdf_sdk/react_native';

var config = ComPDFKit.getDefaultConfig({
  modeConfig:{
    initialViewMode: CPDFViewMode.VIEWER,
    availableViewModes: [
      CPDFViewMode.VIEWER,
      CPDFViewMode.ANNOTATIONS
    ]
  }
})

// Use in Modal View
ComPDFKit.openDocument(samplePDF, '', config)

// Use in UI components
<CPDFReaderView
	document={this.samplePDF}
	configuration={config}
	style={{ flex: 1 }}
/>

Set the list of enabled annotation types and default annotation attribute values. For example, enable only highlight annotations and set the color and transparency for highlight annotations:

import { ComPDFKit, CPDFAnnotationType, CPDFConfigTool } from '@compdfkit_pdf_sdk/react_native';

var config = ComPDFKit.getDefaultConfig({
  annotationsConfig: {
    availableType: [
      CPDFAnnotationType.NOTE
    ],
    availableTools: [
      CPDFConfigTool.SETTING,
      CPDFConfigTool.UNDO,
      CPDFConfigTool.REDO,
    ],
    initAttribute: {
      note: {
        color: '#1460F3',
        alpha: 255
      }
    }
  }
})

// Use in Modal View
ComPDFKit.openDocument(samplePDF, '', config)

// Use in UI components
<CPDFReaderView
	document={this.samplePDF}
	configuration={config}
	style={{ flex: 1 }}
/>

Set the display mode and page flipping direction:

import { ComPDFKit, CPDFDisplayMode } from '@compdfkit_pdf_sdk/react_native';

var config = ComPDFKit.getDefaultConfig({
  readerViewConfig: {
    displayMode: CPDFDisplayMode.DOUBLE_PAGE,
    verticalMode: false
  }
})
// Use in Modal View
ComPDFKit.openDocument(samplePDF, '', config)

// Use in UI components
<CPDFReaderView
	document={this.samplePDF}
	configuration={config}
	style={{ flex: 1 }}
/>
