react-native-pdf-spaceo


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

$3

* 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

$3

We use rn-fetch-blob to handle file system access in this package,
So you should install react-native-pdf-spaceo and rn-fetch-blob

``bash
npm install rn-fetch-blob --save
npm install react-native-pdf-spaceo --save

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

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 :

`
NSAppTransportSecurity

NSExceptionDomains

yourserver.com


NSIncludesSubdomains


NSTemporaryExceptionAllowsInsecureHTTPLoads


NSTemporaryExceptionMinimumTLSVersion
TLSv1.1



`

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