I’ve been on the hunt for an open source screen cature tool for the Mac. I finally found what I was looking for, a tool that in which you can specify the exact size of the capture window. Let me explain…

In the process of creating screenshots to accompany applications submitted to the App Store, you can include up to 5 images. Although the images can be anything you like, typically the images consist of screenshots of an application running in the iPhone simulator.

Sometimes all you’re really looking for is a basic chunk of code to get something done. For example, I was working on an application yesterday and needed to display the current date in text format: October 29, 2008. A simple concept for sure, however, with the many nuances of date formatters, it takes some time to pull together the “right” code.

In a previous post I introduced how to use #pragma mark to help navigate source files within Xcode. There are several additional tags that can be used within a source file to call out specific code or content.
