+Integrate PSPDFKit for React Native on iOS using CocoaPods
+
+
+1. Create the app with react-native init YourApp.
+2. Step into your newly created app folder: cd YourApp
+3. Install react-native-pspdfkit from GitHub: yarn add github:PSPDFKit/react-native#rad/podspec (#rad/podspec is temporary, as the change is only on that branch)
+4. IMPORTANT: Do not link module react-native-pspdfkit: Do not use react-native link react-native-pspdfkit
+5. Create the folder PSPDFKit and copy PSPDFKit.framework into it.
+6. Open ios/YourApp.xcodeproj in Xcode: open ios/YourApp.xcodeproj
+7. Make sure the deployment target is set to 9.0 or higher: 
+ deployment-target.png 
+
+1. Change "View controller-based status bar appearance" to YES in Info.plist: 
+ deployment-target.png 
+
+1. Change your bundle ID to match the one for which you have a PSPDFKit license
+2. Close the Xcode project
+3. Run react-native run-ios to make sure your app runs before adding PSPDFKit
+4. Go back to the terminal and run pod init
+5. Replace the content of your newly created Podfile with this:
+
+
+target 'YourApp' do
+  # Native Navigation uses Swift, so this line is required!
+  use_frameworks!
+
+
+  pod 'react-native-pspdfkit', :path => '../node_modules/react-native-pspdfkit'
+
+
+  # To use CocoaPods with React Native, you need to add this specific Yoga spec as well
+  pod 'Yoga', :path => '../node_modules/react-native/ReactCommon/yoga/Yoga.podspec'
+
+
+  # You don't necessarily need all of these subspecs, but this would be a typical setup.
+  pod 'React', :path => '../node_modules/react-native', :subspecs => [
+    'Core',
+    'RCTText',
+    'RCTNetwork',
+    'RCTWebSocket', # needed for debugging
+    'RCTAnimation',
+    'RCTImage',
+    'RCTNetwork',
+        'BatchedBridge', # https://github.com/facebook/react-native/issues/14749
+    # Add any other subspecs you want to use in your project
+  ]
+
+
+  # Add any other dependencies here, including any 3rd party native libraries that you depend on for
+  # React Native.
+end
+
+
+1. Run pod install
+2. Open the newly created workspace: YourApp.workspace
+3. Copy PSPDFKit into the Pods folder: YourApp/ios/Pods[a]
+4. Drag and drop if from the Finder into the RCTPSPDFKit group:
+ drag-and-drop.png 
+
+1. Add it to the react-native-pspdfkit framework:
+ add-to-react-native-pspdfkit.png 
+
+1. Embed YourApp/ios/PSPDFKit/PSPDFKit.framework (not the copy from YourApp/ios/Pods/PSPDFKit.framework) by drag and dropping it into the "Embedded Binaries" section of the "YourApp" target (Select "Create groups"). This will also add it to the "Linked Frameworks and Libraries" section:
+ embedding-pspdfkit.png 
+
+1. 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: 
+ adding-pdf.png 
+
+1. Replace the default component from index.ios.js with a simple touch area to present the bundled PDF:
+
+
+import React, { Component } from 'react';
+import {
+ AppRegistry,
+ StyleSheet,
+ NativeModules,
+ Text,
+ TouchableHighlight,
+ View
+} from 'react-native';
+
+var PSPDFKit = NativeModules.PSPDFKit;
+
+PSPDFKit.setLicenseKey('INSERT_YOUR_LICENSE_KEY_HERE');
+
+// Change 'YourApp' to your app's name.
+class YourApp extends Component {
+ _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);
+
+
+[a]Symlink does not work. We have to have two instances of PSPDFKit.framework on disk. We need to do better here.
