Recently I needed to automate the retrieval of the build number for the app I am currently developing, and instead of including the build number in a standard UI component like a UILabel, I needed to add it dynamically to some HTML that was being used as an About Us view. The solution was pretty simple, but I thought I’d share it anyway since it was fun. The first thing to do is edit the HTML, so at the place I needed to insert the build number, I simply added a rudimentary replaceable tag to the body of the HTML: <p>Build: [BUILD_NUMBER]<p> The next step was to add a method (though I could have also done this inline) to replace[…]

I was doing a little research to see if I could use my retired iPhone 4 as an iBeacon test device for either advertising or detecting, and unfortunately the answer is no. Here is the list of Apple devices that officially support iBeacon, taken from the Apple KB article iOS: Understanding iBeacon (KB: HT6048): To use iBeacon, you need iOS 7 or later, Bluetooth turned on, and a compatible iOS device: iPhone 4s or later iPad (3rd generation) or later iPad mini or later iPod touch (5th generation) or later I was a little disappointed, but not really surprised. The iPhone 4 can barely run iOS 7, so it’s usefulness is rapidly declining, especially on the eve of WWDC 2014[…]
