Edit: The image view now has a dedicated page, and also is available in binary format (you can just drop in your Application’s folder, no need to recompile ^^) The page is : http://blog.pcitron.fr/tools/macosx-imageviewer/

I’ve been learning Objective-C and Cocoa development since a few months now, and after I had followed a few tutorials, I decided to start a little image viewer project : it’s fun to do, and cover a lot of interesting areas of Cocoa programming.

Now I think I’ve reached the first usable version of the software, and I thought I might release it. It’s really really simple. It allows you to browse through your computer, the images contained in a browser are shown as thumbnails, and when clicking on them, you have a bigger preview. If you double click a thumbnail (or press Enter when one is selected) you enter a fullscreen mode. That’s all (the menu options are not implemented yet)

But the source code might interest a few beginners since it covers a few points I found hard to learn :

• custom cells in the NSOutlineView (it allows to display the folder icons next to the name)
• use of the user defaults to remember the size and position of the window between each run, and save other stuff
• programmatically bind the background color of an IKImageBrowserView to the user defaults
• how to use the fullscreen mode of an NSView

Bellow is a screenshot of the application, and here is the link to the XCode sources : ImageViewer v0.1
