What happened?
In spite of plenty of advance warning from Twitter, we got caught by the Twitpocalypse bug.
For the 2.0.1 release, we had tested our software extensively. I actually wrote an emulation layer on top of the code that reads data from Twitter that added a large number to every ID read from Twitter. This testing [...]
The general consensus is that there will be a new iPhone announced next week. I, like others, think it’s going to have new features and capabilities. But how is Apple going to label this new device?
iPhone 3G?
It’s entirely possible that Apple will keep the same name as the previous version. There’s precedence in the Mac [...]
Another area where I find iPhone development to be a bit convoluted was with toolbars and action sheets. The sheets are conceptually tied to the toolbar, yet there is no glue to combine UIActionSheet with UIToolbar. It’s also fairly difficult to represent your application state in the toolbar—an example is the refresh button in Twitterrific [...]
Every once in awhile you read a blog post that completely changes the way you think about a problem. Matt Gallagher’s Cocoa With Love is one of those blogs where it happens often. If you’re not subscribing to his RSS feed, do it now.
In particular, this post addressed a problem that every iPhone developer has [...]
Assume the following:
You have an application that you’re selling on the App Store. This application, MyApp 1.0, works on both iPhones and iPod touches with the 2.2.1 firmware.
The compelling new APIs in iPhone SDK 3.0 allow you to implement a bunch of great new features in your product. Let’s say you add a Map View [...]
Everyone and his brother has a prediction about Apple and the mythical “netbook.” This is mine.
Before I get into the actual prediction, let me say that I’ve come to this conclusion by looking at Apple as a business, not as a supplier of shiny gadgets for our technolust. As much as we love the things [...]
If you’re reading my essays, it’s likely that you’re selling some kind of software on the Internet. (Or soon will be.)
To be successful at this endeavor, you need to monitor your sales and plan development around the revenue. Ask anyone who’s had success with a software product, and I can guarantee you that they have [...]
A lot of people stumble upon this website because they’re looking for information about developing applications for the iPhone. If this is your first time here, welcome!
I have been developing applications for the iPhone since it was released (using both the Jailbreak and official SDK.) My company is currently selling several applications in iTunes. I [...]
Many of you are starting to realize that a ringtone price point does not sustain a business. I’m with you.
Lately, I’ve been thinking about ways to make higher prices more palatable to customers. Several discussions at Macworld kicked off these thoughts, and a recent tweet by Justin Williams made me realize that a lot of you [...]
Dear Steve,
As an iPhone developer who’s been in the App Store since its launch, I’m starting to see a trend that concerns me: developers are lowering prices to the lowest possible level in order to get favorable placement in iTunes. This proliferation of 99¢ “ringtone apps” is affecting our product development.
Unlike a lot of other [...]
