Introduction

DMSplitView is a revisited version of the standard OSX's NSSplitView control. The e problem with NSSplitView is that some things which should be simple require implementing unintuitive delegate methods, which gets to be pretty annoying. DMSplitView offer a powerful control over some important settings of NSSplitView such like:

• subview's size and constraint (Specificy uniform, proportional, or priority-based resizing, min/max sizes for subviews)
• dividers positions
• collapsible subviews (specify whether a subview can collapse)
• animatable transitions (both on dividers and subview's sizes)
• control over divider thickness and style
• save/restore state of dividers (using standard's OS X autosave feature)

Special thanks:

• CocoaWithLove blog for it's work on priority based NSSplitView implementation
• Seth Willits for it's AGNSSplitView implementation.
