  • UITableViewCell AccessoryType Toggling

    I recently battled with this feature: to create a toggling checkmark on a UITableViewCell, between two different cells. Here is the solution, in brief. The tableview loads from an array that contains arrays- each array is a section. The one in question contains two values – the option values, @”A” and @”B”. We’ll call it […]

  • Ephemera Demo

    This is the live presentation of our iPad app, Ephemera, from hack/hackers event a month ago. Thanks so much to Rich for the filming and editing! It’s *so nice* to be able to listen to the judges without the panic of being onstage, I have to say. It’s kind of painful to see such a […]

  • Pumping Up Ephemera

    So doing some work lately on Ephemera- that’s the iPad app that consolidates local museum media on a Google Maps interface, so you can get a timeline view of your city. What have I done? – Created the timeline! Now you can scroll over time and view all of the media. – Click over to […]

  • Ephemera: iPad App

    My project partner Stacy Bond (that’s Bond, Stacy Bond) and I built and presented our iPad app at Hack/Hackers Unite this weekend. Our project? “Ephemera” an overlay of the map of SF with local trivia/history. The app locates you, and shows all of the annotations for local treasures around you. You can also click over […]

    I have a few apps that are open source & the code is available: CootieCatcher Currently in store. This is a “teach girls to program” game, it’s a release. Using Core Data and some basic animation to create a fortune-telling game. I’m the only developer. Le Bingueau A bingo game to help you […]

  • Directory Issues with xCode Projects & SVN/Google Code

    I encountered this problem: getting an “already under source control” error when I tried to add my *.xcodeproj file to svn. I was struggling with some issues after I renamed my iPhone project. I had done this before with another project. The file in question was my iPhone project file, “*.xcodeproj”. It appears as a […]

  • iPhone Development: Layers, Color and Core Animation

    I’m reading Marcus Zarra and Matt Long’s book Core Animation– it’s written on a framework/library mainly for the Mac OS, but I’m using it to learn about iPhone development. So I’m trying all of the exercises, on the iPhone. There are occasional notes regarding the difference, but here is example chapter 5, “Scale Transform,” rewritten […]

  • iPhone Development: Game Kit, and What is a Picker?

    So as usual, I wish someone had written this in a blog post. And now that I’ve figured it out, I’m paying it forward, so to speak. The big revelation here is: if you’re using Game Kit (GK) foundation from Apple, iPhone development 3.x SDK, then you may encounter a networking object called “PeerPickerController”. It […]

  • iPadDevCamp New Developer Award. Wow.

    I can’t think of a title for this post- there’s so much to say. The short version: I attended an intense 2-day hackfest for the iPad down at the eBay offices in San Jose, called iPadDevCamp (used to be iPhoneDevCamp). We were hesitant app developers, we made a tiny little dice throwing app – connecting […]

  • iPhone Dev: Troubleshooting NavigationControllers in Interface Builder

    In the simple example explained in this tutorial, and others, there are a few key points that I wish I’d seen in a blog somewhere, ha. It’s best to deal with literals, so I am recreating the example quickly, with notes on what aspects to check. If you have a complex or already created app, […]
