Last night I gave the Understanding Objective-C Inside and Out talk at CocoaHeads Ann Arbor. You can find my slides on SpeakerDeck.
We had a really great turnout—CocoaHeads Ann Arbor is almost outgrowing its space! If you’re in the SE Michigan area (or even further—there are attendees from Kalamazoo and Grand Rapids) you should come to the next meeting and learn about Auto Layout.
