Automatically Link Native Modules

For 0.29.2+ projects, simply link native packages via the following command (note: rnpm has been merged into react-native)

`
react-native link
`

As for projects < 0.29 you need rnpm to link native packages

`sh
rnpm link
`

Manually Link Native Modules

1. Run npm install react-native-document-edoc2 --save
2. Open your project in XCode, right click on Libraries and click Add
Files to "Your Project Name" (Screenshot) then (Screenshot).
3. Add libRNDocumentPicker.a to Build Phases -> Link Binary With Libraries
(Screenshot).

CocoaPods

Add the following to your podfile:
`
pod 'react-native-document-edoc2', :path => '../node_modules/react-native-document-edoc2
``

`gradle
// file: android/settings.gradle
...

include ':react-native-document-edoc2'
project(':react-native-document-edoc2').projectDir = new File(rootProject.projectDir, '../node_modules/react-native-document-edoc2/android')
`

`gradle
// file: android/app/build.gradle
...

dependencies {
...
compile project(':react-native-document-edoc2')
}
`

`java
// file: MainApplication.java
...

import com.reactnativedocumentpicker.ReactNativeDocumentPicker;; // Import package

public class MainApplication extends Application implements ReactApplication {

/**
* A list of packages used by the app. If the app uses additional views
* or modules besides the default ones, add more packages here.
*/
@Override
protected List getPackages() {
return Arrays.asList(
new MainReactPackage(),
new ReactNativeDocumentPicker() // Add package
);
}
...
}
`

Example

`javascript
import { DocumentPicker, DocumentPickerUtil } from 'react-native-document-edoc2';

// iPhone/Android
DocumentPicker.show({
filetype: [DocumentPickerUtil.images()],
},(error,res) => {
// Android
console.log(
res.uri,
res.type, // mime type
res.fileName,
res.fileSize
);
});

// iPad
const {pageX, pageY} = event.nativeEvent;

DocumentPicker.show({
top: pageY,
left: pageX,
filetype: ['public.image'],
}, (error, url) => {
alert(url);
});

How to send it back ?

I recommend using https://github.com/johanneslumpe/react-native-fs
I had to modify Uploader.m so it would use NSFileCoordinator with NSFileCoordinatorReadingForUploading option.

I added a check for file length that would be thrown into RNFS catch block.
`obj-c
if ([fileData length] == 0) {
NSError *errorUp = [NSError errorWithDomain:@"com.whatever.yourapp" code:77 userInfo:[NSDictionary dictionaryWithObject:@"empty" forKey:NSLocalizedDescriptionKey]];
_params.errorCallback(errorUp);
return;
}
`


`javascript
let url = "file://whatever/com.bla.bla/file.ext"; //The url you received from the DocumentPicker

// I STRONGLY RECOMMEND ADDING A SMALL SETTIMEOUT before uploading the url you just got.
const split = url.split('/');
const name = split.pop();
const inbox = split.pop();
const realPath = ${RNFS.TemporaryDirectoryPath}${inbox}/${name};

const uploadBegin = (response) => {
const jobId = response.jobId;
console.log('UPLOAD HAS BEGUN! JobId: ' + jobId);
};

const uploadProgress = (response) => {
const percentage = Math.floor((response.totalBytesSent/response.totalBytesExpectedToSend) * 100);
console.log('UPLOAD IS ' + percentage + '% DONE!');
};

RNFS.uploadFiles({
toUrl: uploadUrl,
files: [{
name,
filename:name,
filepath: realPath,
}],
method: 'POST',
headers: {
'Accept': 'application/json',
},
begin: uploadBegin,
beginCallback: uploadBegin, // Don't ask me, only way I made it work as of 1.5.1
progressCallback: uploadProgress,
progress: uploadProgress
})
.then((response) => {
console.log(response,"<<< Response");
if (response.statusCode == 200) { //You might not be getting a statusCode at all. Check
console.log('FILES UPLOADED!');
} else {
console.log('SERVER ERROR');
}
})
.catch((err) => {
if (err.description) {
switch (err.description) {
case "cancelled":
console.log("Upload cancelled");
break;
case "empty"
console.log("Empty file");
default:
//Unknown
}
} else {
//Weird
}
console.log(err);
});
`

File Type

All type of Files ` 'public.allFiles' or DocumentPickerUtil.allFiles()`

Only PDF ` 'public.pdf' or DocumentPickerUtil.pdf() `

Audio ` 'public.audio' or DocumentPickerUtil.audio()`

Plain Text ` 'public.plainText' or DocumentPickerUtil.plainText() ``

Reminder

You need to enable iCloud Documents to access iCloud

Halp wanted: Improvements

- Fix Xcode warning about constraints
- support options for the UIDocumentMenuViewController
- Handle Upload by itself ?
