When I learn things about Cocoa I wish there had been some easy tutorial out there that explained in a simple way what I had just learned.
So yesterday I wanted to figure out how to add custom toolbar item to a toolbar. I dug around and the best tutorial I found was at www.macdevcenter.com. I read it and after a while figured out how it was creating toolbars items.
Yet I felt it was more complex then it could be. It build off old tutorials and had a lot of extra code which wasn't relevant to problem I was trying to solve.
So I decided to use what I had learned and make my own tutorial.
