Have you tried to add the following line?

[nLayer setValue:[NSNumber numberWithFloat:.9999] forKeyPath:@"transform.scale"];

Hello well finally I manage to rotate the CALayer each time I click on it. what I did was the following:

-(void)mouseDown:(NSEvent *)event
{
	[event retain];
	[mouseDownEvent  release];
	mouseDownEvent = event;
	NSPoint p2 = [event locationInWindow];
	NSPoint p3 = [self convertPoint:p2 fromView:nil];
	CGPoint p = NSPointToCGPoint(p3);
	CALayer * nLayer = [_gameboardLayer hitTest:p];

if (nLayer.name != nil) {

NSNumber* value = [NSNumber numberWithFloat:PERP()];
value = [NSNumber numberWithFloat:[value floatValue] + [[nLayer valueForKeyPath:@"transform.rotation.z"] floatValue]];
[nLayer setValue:value forKeyPath:@"transform.rotation.z"];

}

}


#define PERP () (90 * M_PI / 180)

but I realize that each time the images its perpendicular its kinda blurry I dunno how to rotate the layer without loosing quality.

the contents of the layer its .png


Thanks
