I understand there are 1127 apps about custom emoji keyboard on App Store. Since I wish to not put the exact app idea here, I will give an example.
If I wish to build a custom keyboard with custom emojis, is it actually possible? I don't only mean if that is possible technically. I'm also asking if Apple actually allow it?
I tried doing my research and some sites say, they only allow emojis that are built into the phone and not custom.
Again, I don't want to make a chat app where my emojis will be useable. I want to make a keyboard app and if both users have the keyboard, the emojis will work perfectly. The keyboard should be useable throughout iOS environment.
Is this possible and does Apple allow it?
If yes, I would really appreciate some starting point guidelines since I'm a VERY new to iOS.
Thank you!
