Adding a button to user home screen - ios

I would like to ask if there is a possibility to add button into user homescreen. Let's assume I have an app, when user do something with app I want to add a button into user homescreen. I'm thinking about something similar to "Add to Home Screen" from Safari app.

You can add web link icon on home screen, and no way you can add some buttons with custom actions on home screen. Every "button" is application or link icon and nothing more

Home Screen Quick Actions
Home screen quick actions are a convenient way to perform useful, app-specific actions right from the Home screen. People can get a menu of available quick actions when they touch and hold an app icon (on a 3D Touch device, people can press briefly on the icon to see the menu).

Can an iOS app add a website shortcut to the Home Screen?

Could a button in an iOS app trigger a process to add a website shortcut to the device Home Screen?
For example company A releases an app through the App Store. This contains a button to add a shortcut to company A's website on the Home Screen of the phone or tablet.
Cheers.
I was looking to achieve something similar once & I am pretty sure it cannot be done -- iOS simply won't allow it.
You have 3 options for your button action --
Present UIActivityViewController with your website Url (it will the have option to "Add to Reading List", but it won't have "Add to Home Screen")
Present SFSafariViewController with the website Url, you can open an alert view to tell the user to add to bookmarks perhaps. (it will the have option to "Add to Reading List" & "Add to Bookmarks", but it won't have "Add to Home Screen")
Launch Safari & open the website with some parameter triggered javascript code to tell the user to select "Add to Home Screen".
None of them come close to what you want and are not particularly elegant. But I don't see any other way.
(In our case, we just went with launching the Safari)
Here's an old link I found, not much has changed --

iOS App Facebook Login Screen with Logo

I have written an app that uses Facebook login via the FBSDKLoginButton. The login window shows up and the user can login using their Facebook email and passowrd... that all works great!
I am trying to figure out how to make the login window show our company logo but I cannot find this anywhere in the documentation.
Can someone point me in the right direction? I have seen many other iOS Apps that use FB Login and have their logo displayed so I know it can be done.
Here is a screenshot:
You should change the app icon of your Facebook app in order to do that.
Navigate to developers.facebook.com.
Click on My Apps on the top right corner.
Select your app.
Select Settings/Basic from the menu on the left.
Hover over the section called App Icon (which is on the bottom left of the first editable section) and click on the Edit button.
