I'm developing an app which needs its own contacts to be visible in their contacts. Like Whatsapp, I need to show the contact nos that they are registered in my app.
For example, If you add a Friend's whatsapp no in contacts, it will show Found in Whatsapp. So I'm also need the same kind of functionality for my app.
When i install my app, my app should be added to the above list. (Have a look at above screenshot).
I've searched and found nothing about this. So any help would be greatly appreciated.
Just add the below snippet into your info.Plist to get your app name in list
<key>NSUserActivityTypes</key>
<array>
<string>INStartAudioCallIntent</string>
</array>
finally i found the solution , if u add callkit and need to config , then it will added on the list , https://developer.apple.com/library/content/samplecode/Speakerbox/SpeakerboxUsingCallKittocreateaVoIPapp.zip , download the source and run the project , after installation complete open contacts and add social profile, then you will find 'Speakerbox' on the social profile.
