Dimitri Hi
using CAAnimation this is what I was doing:
-(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) {
NSLog(@"%@",[nLayer name]);
CAAnimation* rotateAnimation = [self animateForRotating];
[rotateAnimation setValue:nLayer forKey:@"rotatedLayer"];
[rotateAnimation setDelegate:self];
[nLayer addAnimation:rotateAnimation forKey:@"whatever"];
}
}
-(CAAnimation *)animateForRotating
{
float radians = 90 * M_PI / 180;
CATransform3D transform;
transform = CATransform3DMakeRotation(radians, 0, 0, 1.0);
CABasicAnimation* animation;
animation = [CABasicAnimation animationWithKeyPath:@"transform"];
animation.toValue = [NSValue valueWithCATransform3D:transform];
animation.duration = 0.4;
animation.cumulative = NO;
return animation;
}
but hte animation once finished returned the layer to the initial
position something undesirable, I then set up a animation.autoreverse
= NO; but that didn't help either. I can see here, somehow using
CAAnimation its better, I can have more control on how the rotation
should look.
What do you think?
Thanks tons for your help

As for using CABasicAnimation so you could use the delegate calls,
set the property (or key path) to the final value before adding the
animation to the layer, and you should get more appropriate results
as the animation ends. Additionally, you might need to wrap the
property call in a CATransaction to disable actions, but I don't
know if it's absolutely necessary.
