A react native PDF view component (cross-platform support)

• read a PDF from url/local file/asset and can cache it.
• display horizontally or vertically
• drag and zoom
• double tap for zoom
• support password protected pdf
• jump to a specific page in the pdf

The table below shows the supported versions of React Native for different versions of react-native-pdf.

We use rn-fetch-blob to handle file system access in this package, So you should install react-native-pdf and rn-fetch-blob Notice: rn-fetch-blob v0.10.14 has a bug, please use v0.10.13

npm install rn-fetch-blob --save
npm install react-native-pdf --save

react-native link rn-fetch-blob
react-native link react-native-pdf

if you use RN 0.59.0+, please add following to your android/app/build.gradle

android {

+    packagingOptions {
+       pickFirst 'lib/x86/libc++_shared.so'
+       pickFirst 'lib/x86_64/libjsc.so'
+       pickFirst 'lib/arm64-v8a/libjsc.so'
+       pickFirst 'lib/arm64-v8a/libc++_shared.so'
+       pickFirst 'lib/x86_64/libc++_shared.so'
+       pickFirst 'lib/armeabi-v7a/libc++_shared.so'
+     }

   }

Q1. After installation and running, I can not see the pdf file.
A1: maybe you forgot to excute react-native link or it does not run correctly. You can add it manually. For detail you can see the issue #24 and #2

Q2. When running, it shows 'Pdf' has no propType for native prop RCTPdf.acessibilityLabel of native type 'String'
A2. Your react-native version is too old, please upgrade it to 0.47.0+ see also #39

Q3. When I run the example app I get a white screen / the loading bar isn't progressing on IOS.
A3. Check your uri, if you hit a pdf that is hosted on a http you will need to add an exception for the server hosting the pdf in the ios info.plist. Here is an example :

<key>NSAppTransportSecurity</key>
<dict>
  <key>NSExceptionDomains</key>
  <dict>
    <key>yourserver.com</key>
    <dict>
      <!--Include to allow subdomains-->
      <key>NSIncludesSubdomains</key>
      <true/>
      <!--Include to allow HTTP requests-->
      <key>NSTemporaryExceptionAllowsInsecureHTTPLoads</key>
      <true/>
      <!--Include to specify minimum TLS version-->
      <key>NSTemporaryExceptionMinimumTLSVersion</key>
      <string>TLSv1.1</string>
    </dict>
  </dict>
</dict>

Q4. why doesn't it work with react native expo?.
A4. Expo does not support native module. you can read more expo caveats here

Q5. Why can't I run the iOS example? 'Failed to build iOS project. We ran "xcodebuild" command but it exited with error code 65.' A5. Run the following commands in the project folder (e.g. react-native-pdf/example) to ensure that all dependencies are available:

yarn install (or npm install)
cd ios
pod install
cd ..
react-native run-ios

• setPage

Methods operate on a ref to the PDF element. You can get a ref with the following code:

return (
  <Pdf
    ref={(pdf) => { this.pdf = pdf; }}
    source={source}
    ...
  />
);

setPage(pageNumber)

Set the current page of the PDF component. pageNumber is a positive integer. If pageNumber > numberOfPages, current page is not changed.

Example:

this.pdf.setPage(42); // Display the answer to the Ultimate Question of Life, the Universe, and Everything
