Adam, I noticed some leaks in FVColorMenuView, basically anytime a view was created it was leaked, because you did not take into account the initial retain top-level nib objects get. I also improved the archiving so your awakeFromCoder hack is no longer necessary.
Thanks; IIRC I thought NSNib didn't have that issue, although Apple's example demonstrates it pretty clearly. Oops.
In case anyone's interested, I created a project for FileView last year on googlecode [1]. I no longer recall everything that's changed, but here's a rough summary:
- Rewrite of all image scaling (now uses vImage) and caching (no longer uses DTSource). This reduced memory footprint, but may be slower in terms of clock time.
- There's also a caching malloc zone that fixes some instrumentation issues with using vm_allocate directly, and avoids a lot of the heap overhead inherent in >16K allocations with OS X's malloc.
- In the view itself, I rewrote the grid layout and fixed some major consistency problems (and drawRect: no longer causes layout changes). I also factored a bunch of the controller logic out, fixed the bindings support, and added an IB3 palette. AFAIK this all works, although there's an occasional scroller hiding issue I haven't been motivated to track down.
