# react-native-render-pdf

[![npm](https://img.shields.io/npm/v/react-native-render-pdf.svg?style=flat-square)](https://www.npmjs.com/package/react-native-render-pdf)

A high performance & feature rich React Native PDF View component written in Obj-C++ for iOS, Kotlin for Android and C++ for Windows

### Feature

- read a PDF from url, blob, local file or 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

### Supported versions

We use [`react-native-blob-util`](https://github.com/RonRadtke/react-native-blob-util) to handle file system access in this package,
So you should install react-native-render-pdf and react-native-blob-util

> The table below shows the supported versions of React Native and react-native-blob-util for different versions of `react-native-render-pdf`.

| React Native | 0.57+ |
| ----------------------- | ------- |
| react-native-render-pdf | 1.0.0+ |
| react-native-blob-util | 0.13.7+ |

> 🚨 Expo: This package is not available in the [Expo Go](https://expo.dev/client) app. Learn how you can use this package in [Custom Dev Clients](https://docs.expo.dev/development/getting-started/) via the out-of-tree [Expo Config Plugin](https://github.com/expo/config-plugins/tree/master/packages/react-native-pdf). Example: [`with-pdf`](https://github.com/expo/examples/tree/master/with-pdf).

### Installation

```bash
# Using npm
npm install react-native-render-pdf react-native-blob-util --save

# or using yarn:
yarn add react-native-render-pdf react-native-blob-util
```

Then follow the instructions for your platform to link react-native-render-pdf into your project:

#### Bundling PDFs with the app

To add a `test.pdf` like in the example add:

```

true

```

in the app `.vcxproj` file, before ``.

### 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`](https://github.com/danfordgidraph/react-native-render-pdf/issues/24) and [`#2`](https://github.com/danfordgidraph/react-native-render-pdf/issues/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`](https://github.com/danfordgidraph/react-native-render-pdf/issues/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 :

```
NSAppTransportSecurity

NSExceptionDomains

yourserver.com


NSIncludesSubdomains


NSTemporaryExceptionAllowsInsecureHTTPLoads


NSTemporaryExceptionMinimumTLSVersion
TLSv1.1

```

**Android:**
[`see here`](https://stackoverflow.com/questions/54818098/cleartext-http-traffic-not-permitted)

Q4. why doesn't it work with react native expo?.
A4. Expo does not support native module. you can read more expo caveats [`here`](https://facebook.github.io/react-native/docs/getting-started.html#caveats)

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-render-pdf/example`) to ensure that all dependencies are available:

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

\*) requires building React Native from source with [this patch](https://github.com/facebook/react-native/pull/31789)

### Methods

- [setPage](#setPage)

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

```
return (
{ this.pdf = pdf; }}
source={source}
...
/>
);
```

#### setPage()

`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
```
