October 20, 2008 A quick look at three different approaches for implementing touch detection using the Cocos2d iPhone library. There are a number of snippets here, and I imagine it would be rather confusing to approach without a basic understanding of ObjC and Cocos2d iPhone.
February 24, 2008 A few brief code snippets on how to add an instance of an entity to another entity's one-to-many relationship.
February 16, 2008 A quick look at how to filter NSArrays in Objective C.
August 7, 2008 I spent much too long today trying to figure out how to implementing drag and droping selected text onto an application's Dock icon (and its Finder icon as well), and will proceed to share this knowledge with you in the hopes that related searches will not leave their queriers quite as lost as I was.
April 5, 2008 Recently I spent a while trying to figure out how to open files in my Cocoa app. Not just open them, but have the correct application launch with that file as an argument. I knew that Carbon achieved this with LaunchServices, but was unsure about the Cocoa equivalent to LaunchServices. But, it turns out to be quite easy to use. (Hint: its NSWorkspace.)

This post looks at the small shoves that finally got me over the edge.
November 30, 2008 Loading data from XML files can really clean up your iPhone applications, and the Objective-C code to do so is pretty easy once you figure out a couple of tricks and gotchas. This entry takes a look at how it's done.
