我想访问获取某个时间点的变换比例的值.这是动画创作:

    CABasicAnimation *grow = [CABasicAnimation animationWithKeyPath:@"transform.scale"];
    grow.toValue = @1.5f;
    grow.duration = 1;
    grow.autoreverses = YES;
    grow.repeatCount = HUGE_VALF;
    [view.layer addAnimation:grow forKey:@"growAnimation"];

我希望,例如当用户按下按钮时,视图的当前大小.记录帧或边界始终返回常量值.任何帮助将非常感激 !
