Classes

UnrestrictedLayerView

By default, the layer property of an NSView has a number of restrictions. There are many properties that are owned and controlled by the AppKit, and are impossible to modify in a safe and predictable way. This class provides a single property unrestrictedLayer, which has no restrictions whatsoever.

This layer will just match the frame of the hosting view. This is is a great way to integrate a layer into the Auto Layout system. It’s also nice for applying transforms.

NoSelfHitTestingView

A really simple view that will never become first responder due to a mouse down event. This is handy for routing clicks down into other parts of the view hierarchy.

XiblessViewController

This is a very simple NSViewController subclass that eliminates some boilerplate for view controllers that always create their views programatically. This class is based on work on a blog post about view controllers without XIBs, and includes a lot of great discussion about the pros and cons of such an approach.
