Great job. Both the example - not too simple like so many programming videos - and the presentation skills.

Do you think this will work? I associate a UIView to the View Controller - because I want to create bar graphs and labels using CGRect. And I'm using XML (and a free parser).

Will this code 'wait' for the download and parsing then create the graphics? My current attempts don't appear to - labels get created but either errors for a nil Context or just no graphics.

PS - you main want to explain why you dispatch to the main queue.

where was the json parsing? ha ha. there wasn't any. this video might be valuable for other reasons, but nobody is learning a json parsing methodology by watching this.
