I have a custom view which may have animation. I use an NSTimer to
fire periodically and I check to see if anything is animating in my
view. If so, I call setNeedsDisplay:YES.
If I minimize or hide the application, I notice that drawRect: stops
being called by the system (which I consider good). But if my
view/window is completely obscured by another window (say another
window from my app or from another application such as Safari) , I
noticed that drawRect: is still being called.
As far as a solution goes? You could check to see if the window
containing the view is frontmost, and slow down the drawing timer
if it isn't. This probably isn't ideal (some users may want it to
update normally in the background!), so you may want to make it
optional, and configurable in the preferences. _______________________________________________
