Cocoa Dev Central: MyOneLineOfCodeBrowser using Cocoa and WebKit 1.0
One of the best features of Safari 1.0 is the Web Kit SDK (v1.0). This new Cocoa framework allows you to write a powerful browser with light and simple code. This easy tutorial will guide you in the making of a browser with only one line of Objective-C code.
I haven’t tried this so see if it’s really as easy as all that (if it works for me, it will work for anyone). But I like the idea of this: complete functions that anyone can use to build their own applications.
