Monotouch动画加速

Question

是否有可能以增加的速度创建动画？像加速动画。

我有一些代码，但找不到如何实现它的方法。谷歌搜索也没有帮助。

CABasicAnimation animation = CABasicAnimation.FromKeyPath("opacity"); 
animation.To = NSNumber.FromFloat(0.1f); 
animation.Duration = 1.4f; 
animation.Delegate = new ExponencialSpeedAnimationDelegate(); 
animation.RepeatCount = 3; 
this.Layer.AddAnimation(animation, "opacity"); 

Answer 1

尝试

animation.TimingFunction = CAMediaTimingFunction.FromName (CAMediaTimingFunction.EaseIn);
