You might want to look at SpriteKit.

Everyone, if it will be helpful I offer my solution: I just created a delayed
task that would begin the play of the music a fraction of a second after
requesting the draw of the newly loaded composition. This is pretty clean; the
view does all it wants to do in much less time than I'm giving it,
Jeff,
AV sync issues are definitely tricky. I would be interested in hearing opinions
from others on how they deal with these sync issues.
I think you’re on the right track, in that you’re trying to use messages to
determine when your visual state will match the audio state. As you’re seeing,

Agreed :)

Yes, that would be better. I think even better though would be to design the
app so that the ‘need to know when the view is done’ is not a requirem
That's a bad idea.
Use viewWillDraw for this approach

Jeff,
I was wondering, are you attempting to sync the drawing with the music, or is
this a performance issue you’re seeing?

Noah, yes, thanks, I think that is it. I spoke too soon in my
that-works-perfectly announcement, but this must be the right track to follow.
It's not clear to me when needsDisplay is being cleared in the view; I need to
look into this a little more. So far, needsDisplay is sticking on, or appears

And bingo, that works perfectly. Looks like needsDisplay is exactly what I
wanted. It's easy to check for the one view involved, but I hadn't noticed that
property. So maybe it really was a dumb question.
Thanks, Jeff

Clark, you've got a great idea there. The notification method is perhaps not
the one, because there are circumstances in which a draw method will conclude
that further adjustment is going to be needed and will ask for other sections
to adjust, etc. But the view that matters here is just a single

Instead of looking to the view system to know when your code is done laying
things out, why not ask you
Clark, it's a music app; a piece is composed and placed on the screen; there's
a lot of massaging going on as the music adjusts visually. I want the play of
the example to begin once there are no more updates remaining. That is no
noticeable delay in terms of human time, but makes a difference i

Suppose one wants to do a task in an NSView only once it has no drawRect calls
pending. Is there any way to tell, for a particular NSView, if there are any
drawing events coming up? Whether, that is, the view is up to date?
I've tried counting my explicit uses of setNeedsDisplay and decrementing
