{
var _fromValue = layer.ValueForKeyPath ( new NSString ( key));
var _toValue = new NSNumber (toValue);
var _key = new NSString (key);
var barAnimation = CABasicAnimation.FromKeyPath (key);
var currentValue = _fromValue;
if (layer.PresentationLayer != null) {
currentValue = layer.PresentationLayer.ValueForKeyPath (_key);
}
barAnimation.From = currentValue;
barAnimation.To = _toValue;
