ios - iphone - 动画跳回原始状态

Question

下面是我使用的代码。动画有效。然而，它在它之后又跳回了原来的状态。我的代码有什么问题吗？谢谢。

-(void)touchesEnded:(NSSet *)touches withEvent:(UIEvent *)event{
    CABasicAnimation *expand=[CABasicAnimation animationWithKeyPath:@"transform"];
    expand.toValue=[NSValue valueWithCATransform3D:CATransform3DMakeScale(1.2, 1.2, 1.0)];
    expand.autoreverses=NO;
    expand.removedOnCompletion=YES;  

    CABasicAnimation *opacityAnimation = [CABasicAnimation animationWithKeyPath:@"opacity"];
    opacityAnimation.toValue  = [NSNumber numberWithFloat:0.0f];
    opacityAnimation.autoreverses=NO;
    opacityAnimation.removedOnCompletion=YES;

    CAAnimationGroup *group=[CAAnimationGroup animation];
    group.animations=[[NSArray alloc] initWithObjects:expand,opacityAnimation, nil];
    group.duration=1.0;
    group.fillMode=kCAFillModeForwards;
    group.timingFunction=[CAMediaTimingFunction functionWithName:kCAMediaTimingFunctionEaseOut];
    [view1.layer addAnimation:group forKey:@"expand"];

}

您正在将 removedOnCompletion 设置为 YES，这指定动画完成后将被删除。请尝试使用 NO。
