I figure that by the time outside developers like me see something for the first time, Apple engineers have been living with that thing for many months, so they’ve likely got a much better idea than I do about the best way to use that new thing.
But, after spending time with their stuff, sometimes — not often, but sometimes — I disagree with what appears to be Apple’s recommended “best practice” for doing something. I think I’ve come to the decision that the IBOutlet behavior in iOS is one of these areas.’

I learned something new: “Notice the simulator does not execute ARM code, when building for the simulator your app is compiled for x86 and executes natively, so none of the following applies when running on the simulator, you need to be running on target.”]]>developer@akamaiapps.comEditorials2010-08-31T19:58:15-05:00http://www.akamaihaole.com/page2/files/957891d7305f23d973c6237ec92902e4-0.html#unique-entry-id-0http://www.akamaihaole.com/page2/files/957891d7305f23d973c6237ec92902e4-0.html#unique-entry-id-0A great back-story of the computer industry, for a computer that has largely been forgotten:  http://arstechnica.com/hardware/news/2007/07/a-history-of-the-amiga-part-1.ars]]>
