FAQ

FAQ details

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/gray screen / the loading bar isn't progressing . A3. Check your uri, if you hit a pdf that is hosted on a http you will need to do the following:

iOS: 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>

Android: see here

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
