So, just FYI, I have never made an app. Don't know Obj-C, or anything. But I've been tasked with creating a simple HelloWorld app which displays a button, and when clicked a popup with just a HelloWorld text comes up. Now, I've created the project, and I've moved a rect button onto the window. And that displays fine (With the text I want on it), but I can't get it to do any action onclick. Where do I even edit the file to add an onclick event? (Err..ontouch?) Sorry, extremely newbie here. I'm sure this will take you guys a grand total of 5 seconds to explain to me.
