Alex, nice work firstly. I had been searching for this topic for a while and your post solved my problem finally.

A little question though. Is there any reason why you don’t declare the -visibleCellForRow in the header? I assume you don’t want it to be ‘public’ however in my application, I kinda need that. I want to change the height of the cell according to the text view’s height inside it, without the cell in – (CGFloat)listView:(PXListView*)aListView heightOfRow:(NSUInteger)row, this looks impossible to me.

@Michael: Perhaps; although NSScrollView lets you set custom horizontal and vertical scrollers through public methods.

My guess would be that it does something interesting in -setBackgroundABColor: or something with scrolling as -contentViewBoundsDidChangeNotification: is implemented. It also implements -scrollToRect:animated: and -scrollToPoint:animated: which are custom (presumably convenience) methods.

FYI : I think the ABScrollView exists because of the custom NSScroller

@James: That would make a lot of sense – as you can see the class-dumped ABTableView and ABTableViewCell classes are very similar to UITableView and Cell; FastTableView and Cell are pretty similar but look less cloned.

From what I understand, and have heard from colleagues is that Loren Brichter used to work at Apple and worked on UIKit. I imagine he’s just used what he knows from the UITableView and UITableViewCell implementations and reimplemented them for AppKit.

Very interesting! Tweetie probably uses that optimization combined with CoreGraphics pre-blending to achieve such smooth scrolling: http://blog.atebits.com/2008/12/fast-scrolling-in-tweetie-with-uitableview/.
