Replacing system emoji with custom emoji on iOS - ios

I want to replace the system emoji as a user is typing out with my own custom emoji image. I know Facebook Messenger is able to do this on their app so I'm curious how does this work? Their app itself can even turn on/off their own custom emojis. Is it just a custom font?
Here's a link of how it's working:

How to mimic Reminders emoji keyboard behavior?

In my iOS app, I want users to name things they create using emoji only. Ideally, when the special text field becomes active, I want the emoji keyboard to be presented, but without an option to change the language. I've been under the impression it's simply not possible to force this until I found out that's exactly what standard iOS 14 Reminders app does.
When editing the list of reminders, one may tap smiling face and choose one of the emojis. Notice how there's no globe to switch the language.
How can I achieve the same in UIKit or SwiftUI? I don't see any "emoji" UIKeyboardType

If you have created your own custom keyboard, then you are the one who implemented creating the text from the keyboard -> it should be super easy to record the user input (since you are generating it). E.g., if you generate a character using:
self.textDocumentProxy.insertText(characterString)
Then just at the same moment track that character:
self.textGeneratedInThisSession = self.textGeneratedInThisSession + characterString
Assuming there is textGeneratedInThisSession variable into which you are appending the text.
Moreover, at any moment you can just examine the content of self.textDocumentProxy which gives you the power to find out even the content of the document proxy that was generated by other keyboards, e.g.:
let contentDescription = textDocumentProxy.description
Read more in UITextDocumentProxy documentation.
However, you should know that this is something Apple is very sensitive about. Recording the text and leaking it anywhere might very easily end in rejection of the custom keyboard.

Custom emoticon keyboard IOS

I am currently in the process of building a custom keyboard for IOS devices and wanted to add a custom EMOJI keyboard as well. I have a sheet of custom emoticons already created and do not want the user to have to copy and paste into their message like on the Ikea Emoticon keyboard. Is it possible to have a clone of apples keyboard functionality but with my own emoticons?
If you have something similar like below (emoticon icon)
You can make a slideout UIView with a bunch of your custom emojis using UICollectionView. If the user taps on an emoji it would insert your own Unicode Emoji Text (just example).
You will have to make your own if statements if the text contains emoji unicode to make the emojis appear in your text.
This is how I understand it, I might be wrong, if so, please correct me. :)

iOS sharing images with text in messages like Emoji

The goal is to be able to insert images with text when sharing text into an SMS Message from the App as well as in e-mails. Like it is in the picture below. When I try to share images with the UIActivityViewController the images appear on the next line and not next to the text. Is it possible to embed images in text and e-mail like the built in Emoji text?
The contents of text messages are just that, text (that is, a sequence of Unicode code points.) The emoji images you see in the screenshot come from a system font installed on all iOS devices, and are represented in the text as unicode code points, just like the other regular letters in the same message.
If you want to embed custom images into text fields in your app, you can create a custom font that includes the desired graphics (for some code points in the Unicode private use area,) include the font in your app as an asset, configure your text fields to use that font, and then provide some UI for the user to type those code points in.
But remember that this will only work on devices that have your custom font installed, and in apps that choose to use that custom font to display the text — so essentially only in your own app. So for example if you'd send the text in an email or iMessage/SMS to another device, your custom graphics would not work unless a) the receiving device has your custom font installed system-wide, and b) the app displaying the text resolves the Unicode private use area code points you chose to use for your images to this custom font of yours.
If you only want to embed images into text fields within your own app, on iOS 7 and later you can use the text attachments feature that TextKit supports.

Xcode 5 - How to activate Emoji keyboard by default

I want my app to have an only-emoji keyboard. Is this possible to do? Like instead of the english version coming up, it would be emojis. Is it possible to do this without enabling emojis via system preferences? Thanks!
No, the Emoji keyboard has to be activated by the user in the Settings app and there is no way to change this from a 3rd party app.
