In your initWithFrame: method you need to retain the layer object or
the autorelease pool may deallocate it. Also, where do you set the
layer to a view to be displayed?

I think I'm doing those things, see below:
//Setting object as delegate for CALayer
- (id) initWithFrame:(NSRect) frame {
if (self = [super initWithFrame: frame]) {
animateLayer = [CALayer layer];
[animateLayer setDelegate:self];
}
return self;
}
//drawing the view and setting setNeedsDisplay of CALayer to YES
- (void)drawRect:(NSRect)rect {
[self drawBoardBackgroundInRect:rect];
//whenever this next line is not commented out, the program
crashes
//when I try to resize the window
[animateLayer setNeedsDisplay];
}
//Implementation of drawLayer: inContext:
- (void)drawLayer:(CALayer *)theLayer
inContext:(CGContextRef)theContext {
CGRect theRect = CGRectMake(0.5, 0.5, 1, 1);
CGContextSetRGBFillColor(theContext, 1, 0, 1, 1);
CGContextFillEllipseInRect(theContext, theRect );
}
Thanks for your help, you guys are awesome!
