Piechart animation completed event

CGFloat radius = 100;
CAShapeLayer *pieShape = [CAShapeLayer layer];
pieShape.path = [UIBezierPath bezierPathWithRoundedRect:CGRectMake(100, 300, radius, radius)
                                           cornerRadius:radius].CGPath;

pieShape.fillColor   = [UIColor clearColor].CGColor;
pieShape.strokeColor = [UIColor orangeColor].CGColor;
pieShape.lineWidth   = 100;

CABasicAnimation *pathAnimation = [CABasicAnimation animationWithKeyPath:@"strokeEnd"];
pathAnimation.duration = 15.0;
pathAnimation.fromValue = [NSNumber numberWithFloat:0.0f];
pathAnimation.toValue = [NSNumber numberWithFloat:1.0f];
pathAnimation.removedOnCompletion = NO;
pathAnimation.fillMode = kCAFillModeForwards;
[pieShape addAnimation:pathAnimation forKey:@"strokeEndAnimation"];

Above code is working fine. But my problem is how can know that the duration 15 second is completed.

You can tell the animation has completed using the superclass CAAnimation delegate method:

- (void)animationDidStop:(CAAnimation *)theAnimation finished:(BOOL)flag

If the duration is specified as 15.0 seconds and the animationDidStop has been invoked with finished set to YES, the you know that the time has elapsed.
