react-native interface to login to instagram (iOS)

1. npm install react-native-instagram-oauth@latest --save
2. In XCode, in the project navigator, right click Libraries ➜ Add Files to [your project's name]
3. Go to node_modules/react-native/Libraries/LinkingIOS/RCTLinking.xcodeproj ➜ and add RCTLinking.xcodeproj
4. In XCode, in the project navigator, select your project. Add libRCTLinking.a to your project's Build Phases ➜ Link Binary With Libraries
5. Click RCTLinking.xcodeproj in the project navigator and go the Build Settings tab. Make sure 'All' is toggled on (instead of 'Basic'). Look for Header Search Paths and make sure it contains both $(SRCROOT)/../../react-native/React and $(SRCROOT)/../../../React - mark both as recursive.
6. Run your project (Cmd+R)
7. Register a new client on instagram itself => https://instagram.com/developer/clients/manage/

 var RNInstagramOAuth = require('react-native-instagram-oauth');

 var instagram: {
     client_id: '<YOUR CLIENT ID>',
     redirect_url: '<YOUR REDIRECT URL>'  // e.g.: 'test://init'
 };

 function getInstagramByMyself (access_token) {
    fetch('https://api.instagram.com/v1/users/self/?access_token='+access_token)
        .then((response) => response.json()).then((responseData) => {
            console.log(responseData);
        });
 }

 RNInstagramOAuth(instagram.client_id, instagram.redirect_url, (err, access_token) => {
    if (err) { console.log(err) }
    if (access_token !== undefined) {
        console.log(access_token);

        getInstagramByMyself(access_token);

    }
 });

Can be easily used together with react-native-instagram-share (https://github.com/watzak/react-native-instagram-share)
