由于这个原因,应用程序崩溃 -[NSConcreteValue doubleValue]: unrecognized selector sent to

以下代码在我的项目中使用,我搜索非常,我得到原因,因为转换,但如果我将transform.scale替换为它,那么动画改变帮助我!

[viewContent.layer addAnimation:[self getShakeAnimation] forKey:@"transform.scale"];

- (CAAnimation*)getShakeAnimation 
{ 
    CAKeyframeAnimation *animation = [CAKeyframeAnimation animation];

    animation.values = [NSArray arrayWithObjects:
                        [NSValue valueWithCATransform3D:CATransform3DMakeRotation(M_PI_2, 0.0f, 1.0f, 0.0f)],
                        [NSValue valueWithCATransform3D:CATransform3DMakeRotation(M_PI, 0.0f, 0.0f, 0.0f)],
                        [NSValue valueWithCATransform3D:CATransform3DMakeRotation(M_PI * 2, 0.0f, 1.0f, 0.0f)],nil];

 animation.duration = 0.8f;
 animation.delegate = self;


    return animation;
}
