In most of the tutorials out there, you'll see something like didTapButton as and @IBAction name a lot. If you copy and paste the code from these tutorials, you'll have a lot of @IBActions named things like didTapCancelButton. Joachim argues you should not use didTapCancelButton, by instead simply using 'cancel'
I love that Joachim's blog is named "Joachim Complains About Things". This is somewhat trivial but definitely worth pointing out.
