Ios XCode-如何停止CAKeyframeAnimation

ios xcode animation

Ios XCode-如何停止CAKeyframeAnimation,ios,xcode,animation,Ios,Xcode,Animation,我的应用程序中有一个关键帧动画。我想在圆环中移动一个图像，这就是为什么我要使用CAKeyframeAnimation。这是我目前的代码： CAKeyframeAnimation *pathAnimation = [CAKeyframeAnimation animationWithKeyPath:@"position"]; pathAnimation.calculationMode = kCAAnimationPaced; pathAnimation.fillMode = k

我的应用程序中有一个关键帧动画。我想在圆环中移动一个图像，这就是为什么我要使用CAKeyframeAnimation。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"];
现在我想知道，如果用户点击显示器，动画停止，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 RemoveAllianimations]
是，但随后图像视图移回动画（情节提要）之前的位置。我希望它停止在动画中的当前位置
