Summary

In this chapter, you learned everything about iMessage apps. A messages extension is very similar to an app, and it's an exciting, powerful way for you to integrate your apps further into the iOS ecosystem. You now know how you can create a sticker pack to provide your users with a fun, refreshing way to share imagery from your app through standard and custom sticker packs.

Most importantly, you learned that even though iMessage apps can be very complex, they can also be simple. Some iMessage apps will make heavy use of interactive messages, others are merely standard sticker packs, or somewhere in between, such as The Daily Quote. The possibilities are endless and you can have a lot of fun with iMessage extensions. Just be aware that during testing you'll only be able to use your extension in the simulator so, unfortunately, you can't surprise your friends by suddenly sending them stickers from a sticker pack you're still developing.

This chapter wraps up the advanced integrations section of the book. The following chapters will focus on ensuring your app is of top-notch quality and submitting it to the App Store.
