I don't think it has to do with layer release.
If I run it without the animation (commented out the timer creation), the
memory usage in Object Alloc is constant (as expected) at 1.8MB
When I add the timer, the memory usage starts at 1.8MB and goes up to 3MB
after 1 minute, 5MB after 2 minutes, and so on.
The only difference between these 2 cases is "[NSTimer
scheduledTimerWithTimeInterval:0.4 target:self selector:@selector(fromTimer:)
userInfo:nil repeats:YES];" being commented out.
Thanks
