Has this application already been approved by Apple?

If not then you may want to rethink your design before you spend too much time trying to solve this problem. Put simply, if you require users to register on an external site in order to use your app, it is very unlikely to get approved for the app store. The official guideline is:

Apps cannot require user registration prior to allowing access to app features and content that are not associated specifically to the user. User registration that requires the sharing of personal information must be optional or tied to account-specific functionality. Additionally, the requested information must be relevant to the features.

I'm not saying I endorse this requirement, but you should be aware of it so that you don't waste your time solving this problem only to find that Apple won't accept your app.

You can pass some parameters to your registration form when press button in your app, so your site may know what it can redirect to specific scheme url, which will be handled by your application.

Add this entree into Info.plist

<key>CFBundleURLTypes</key>
<array>
    <dict>
        <key>CFBundleURLSchemes</key>
        <array>
            <string>myAppScheme</string>
        </array>
    </dict>
</array>

And now you can redirect user after registration to URL myAppScheme://maybeSomeTokenHere and your application will be launched and pass this parameter to it.
