iOS/Cocoa/Android Development, App Store Releases, Random Diversions, &c
Some of you might remember my crazy idea of pledging to publish an app a week. I thought that this idea would be a good way to force myself to learn a lot about iOS development and actually get things done. And it has! But one thing I did not consider was how downloads of … Continue reading Do free apps increase sales of paid apps?
I’m putting this out here on the internets because I was pulling my hair out about this problem I had. Let me see if I can explain the problem and how I ended up solving it without turning this into a super long story. I’m working on a new app that is basically a brewer’s … Continue reading Possible bug in UITableViewCell didTransitionToState:(UITableViewCellStateMask)state
I have a new app on the iTunes App Store! Allow me to introduce The Beer Nerd’s Olde Volume Equivalence Calculator: It’s a handy little app that lets you compare equivalent prices for different volumes of beer. Interesting? Maybe. In all honesty, I whipped this app up real quick for the following reasons: It uses … Continue reading New app! Also: Xcode + iOS + iPhone 3G tip. Also: insane idea.
I’ve been working on subclassing and improving the venerable UISlider class in iOS’s UIKit framework. Here’s what I was thinking: UISlider is a great way for the user to enter numerical values within a certain range very quickly. It’s immediately responsive and by default gives continual updates as to its value. The problem is that … Continue reading How I Falsified My Most Cherished User Interface Hypothesis
I debated whether or not I should make this post. It seems like most software developers keep sales numbers close to their vests. I suppose I can see why this is (sales data being proprietary company information that might be used by competitors), but I finally decided that that rationale doesn’t really apply to me. … Continue reading iOS and Mac App Store Sales Data for Lens•Lab
So my beautiful and talented wife got an 11″, Core i7 variant of the mid-2011 MacBook Air to write her dissertation on. (The purchase timing was pretty good as her white MacBook’s hard drive just died.) I played around with the Air for a bit and holy moly, it’s FAST! To compare, the computer I … Continue reading 11″ MacBook Air, Core i7: FAST.
Hi, I haven’t updated in about a month. The reason why is that my 9 month old child is now crawling. This means I have far less time than I had before. (You may or may not know that my regular job is professional father.) 🙂 Anyway, I have plans for improving Lens•Lab and I also … Continue reading How I Learned Objective-C
I knew from when I started work on Lens•Lab that I wanted it to be a Universal iOS application, that is, a single binary that runs on the handheld iOS devices (iPhone, iPod Touch) as well as the iPad tablets. This is different from having two separate binaries targeting the two separate families of devices. … Continue reading Thoughts On Universal iOS Apps
The NSOperation class, an abstract class available in Mac OS X 10.5 and newer, is a fantastically simple class to use and makes it very easy to gain performance on Mac OS X computers with multiple processors. The iOS version of Lens•Lab did not have any multi-processor optimizations in it: the only iOS device with … Continue reading Using NSOperation to speed up compute-intensive tasks.
After seeing the sales data, I’m super glad I have this little thing before we set settings for the first time: if ([[[NSLocale currentLocale] objectForKey:NSLocaleCountryCode] isEqualToString:@”US”]) { [userDefaults setInteger:kImperialSegment forKey:@”units”]; } else { [userDefaults setInteger:kMetricSegment forKey:@”units”]; } Half the sales of Lens•Lab are from places outside the US where they use the much more intelligent … Continue reading International Support Quick Note
