- In `App.cpp` add `PackageProviders().Append(winrt::progress_view::ReactPackageProvider());` before `InitializeComponent();`
- If running RNW 0.62, also add `PackageProviders().Append(winrt::RCTPdf::ReactPackageProvider());` and `PackageProviders().Append(winrt::ReactNativeBlobUtil::ReactPackageProvider());`
#### 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/wonday/react-native-pdf/issues/24) and [`#2`](https://github.com/wonday/react-native-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/wonday/react-native-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-pdf/example`) to ensure that all dependencies are available:
```
yarn install (or npm install)
cd ios
pod install
cd ..
react-native run-ios
```

### 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
```
