It’s time to put the finishing touches to our app, which will allow the user to experiment with different Core Image filters then share their result with other apps.
Today’s work requires us to return back to some of the Core Image warts we met earlier, namely the quirky-at-best stringly typed API for Core Image. There is ample room for mistakes here, so take your time, double check your code against mine, and remember Mosher’s Law of Software Engineering: “Don’t worry if it doesn’t work right – if everything did, you’d be out of a job.”
Today you have two topics to work through, in which you’ll put into practice confirmation dialogs, ShareLink
, and more.
That’s another app done – don’t forget to share your progress with the world!
