Written by My Passbook and iBeacon enabled business card was something of a hit at WWDC last week. Some people wanted more detail on how it worked or how to create their own version. This post describes the process, from the perspective of a software developer. If you’re not a developer, there are numerous web sites that […]
I’ll be in San Francisco during WWDC next week (though without a ticket). This is the only time of year I ever think about business cards, and this year I decided that paper business cards suck and it was time to do something cooler. Instead I’ll have an electronic card distributed via Passbook. Electronic cards […]

With rumors swirling about a bigger iPhone 6, I figured I’d touch on them (haha, puns). A few years ago, I thought the idea of a larger iPhone would be something I disliked. With my small-ish hands, even the iPhone 5’s 4 inch screen is too large for me to reach the back button in […]
If you’re writing an iOS app and you need to know the user’s current location, the answer is straightforward: use Core Location. That fires up device GPS (when available). Apple’s A-GPS combines this with things like local Wifi networks and IP addresses to work out the device’s location. All of this, of course, assuming that […]
Over at the Big Nerd Ranch blog, my friend Mark Dalrymple continues his “Inside the Bracket” series with an article on practical uses of Objective-C’s run time introspection. Last time you saw the parts of the Objective-C runtime API that let you query a bunch of the metadata the compiler keeps around once it’s done […]
