Boot Camp Gesture Exercise
Greetings, I'm taking Developer Bootcamp Training, and now on I'm in Module 14, Gestures. However, I really don't get it how to build up this exercise below which I attached screenshot. I'm trying to build up with attempted solution code which is in Gestures.zip, but so far so bad. I don’t understand how to invoke function with actual parameters, and which action I need to use. Please let me know more advanced tips or advices. Thank you.
