Dear Steve,
First, let me congratulate you and everyone at Apple on the release of the iPad. From my dealings with your company, I know it wasn’t easy. Thanks to everyone for busting their asses: a lot of very complex puzzle pieces came together during those last 60 days!
I recently had an encounter with Bill Atkinson. [...]
Here we are on the brink of a new iPhone OS product introduction and developers are facing yet another crunch with device IDs for Ad Hoc testing.
Apple currently lets each iPhone developer, whether a company or an individual account, assign 100 devices for testing purposes. A large chunk of those available devices get used by [...]
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 [...]
