FAQ

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
