Monotouch動畫加速

Question

是否有可能以增加的速度創建動畫？像加速動畫。

我有一些代碼，但找不到如何實現它的方法。谷歌搜索也沒有幫助。

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

嘗試

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