Newer models of the iPad, iPhone, and iPod touch use the Lightning connector instead of the old 30-pin dock connectors. The Lightning connector is smaller and you don't have to worry about inserting it upside-down, so on the whole this is a good change. However, the connector plug is not …

What I've Learned about iOS Development
I've been playing around with development for Mac OS X and iOS for a few years. I've had a pretty good grasp of how Cocoa and UIKit worked, and I've written some simple apps, but for the past month I've been working on my first Real iOS Application. I've had …
Find-My-iPhone Success Story
My wife, stepson, and I carpooled today. I picked them up at school and we made the 45-minute drive back home. As we parked the car, my wife noticed that she didn't have her iPhone.

A common problem for iPhone developers is demonstrating the apps they've developed to others. Showing it on an actual device only works well if you are showing it to one or two people. Showing it in the iPhone Simulator running on a Mac takes a lot of setup, and may …
Native Apps vs. Web Apps
This week, there was a lot of chatter in the blogosphere about the prospect of writing web apps for the iPhone instead of developing native apps.
The furor started with Peter-Paul Koch's profanity-laden rant entitled "Apple is not evil. iPhone developers are stupid.". In this post, PPK asserts that most …
iPhone OS Filename Case Sensitivity
I hit a little snag while adding a feature to an iPhone app today. I added this code to load a logo to be displayed in a view:
UIImage *logoImage = [UIImage imageNamed:@"Icon.png"];This worked fine in the iPhone Simulator, so I thought I was done. I loaded the …
Authenticating with Google App Engine
I've finally got around to doing some work on that iPhone application that I've committed to finishing this month.
On days I do a lot of work on the app, I don't feel obligated to work too hard on the blog, but I will post a little something about whatever …
