我的应用程序中有一个CAKeyframeAnimation。我想在cirlce中移动图像,这就是我使用CAKeyframeAnimation的原因。这是我目前的代码:
CAKeyframeAnimation *pathAnimation = [CAKeyframeAnimation animationWithKeyPath:@"position"];
pathAnimation.calculationMode = kCAAnimationPaced;
pathAnimation.fillMode = kCAFillModeForwards;
pathAnimation.removedOnCompletion = NO;
pathAnimation.duration = 5.0;
pathAnimation.repeatCount = 0;
CGMutablePathRef curvedPath = CGPathCreateMutable();
CGPathMoveToPoint(curvedPath, NULL, 10, 10);
CGRect rectangle = CGRectMake(69,211,239,243);
CGPathAddEllipseInRect(curvedPath, NULL, rectangle);
pathAnimation.path = curvedPath;
CGPathRelease(curvedPath);
[imgView.layer addAnimation:pathAnimation forKey:@"moveTheObject"];
现在我希望如果用户点击显示动画停止并且图像是当前位置。
我该怎么做?
非常感谢

使用[imgView.layer removeAnimationForKey:@"moveTheObject"];
或[imgView.layer removeAllAnimations];

是,但随后ImageView移回动画前的位置(故事板)。我希望它停在动画中的当前位置。
