No, that's not what I mean. You won't see multiple legacyScreenSaver processes,
but you should note that each time you start and stop your screensaver, you
should see the memory and cpu (depending on how much cpu your screensaver
actually uses) usage of legacyScreenSaver increase. You can easily illustrate
this by logging when your ScreenSaverView starts and stops.
-(void) startAnimation
{
[super startAnimation];
NSLog(@"XXXXXXXXXXXXXXXXXXXXXX start %@", self);
// Do whatever else you do in your screensaver.
}
-(void) stopAnimation
{
[super stopAnimation];
NSLog(@"XXXXXXXXXXXXXXXXXXXXXX stop %@", self);
// Do whatever else you do in your screensaver.
}
Using something like those XXXXXXXXXXX will make it easier to filter them in
Console.app. You should see the starts, but not the stops. And logging the
address of self shows you that there are instances of your ScreenSaverView for
every screen and for every launch.
A few minutes ago, legacyScreenSaver is using 1.29G. I then started and stopped
the screensaver twice, letting it run for a bit each time. It's now up to
1.95G. My code to force quit it doesn't always work, because legacyScreenSaver
is just weird.
