c# - Monotouch中UIPanGestureRecognizer的速度如何减慢

Question

当我在手势识别器的单次触摸上平移图像时，它移动图像非常快我如何减慢 UIPanGestureRecognizer 的速度我的代码是

void PanImage (UIPanGestureRecognizer gestureRecognizer)
{
var image = gestureRecognizer.View;
if (gestureRecognizer.State == UIGestureRecognizerState.Began || gestureRecognizer.State == UIGestureRecognizerState.Changed)
{
var translation = gestureRecognizer.TranslationInView (window);
gestureRecognizer.View.Center = new PointF (gestureRecognizer.View.Center.X + translation.X, gestureRecognizer.View.Center.Y + translation.Y);
gestureRecognizer.SetTranslation (PointF.Empty, image);
}
}

您从识别器计算的平移可以除以一个因子以减慢平移效果。

它可以像这样很容易地完成：

var factor =2;

gestureRecognizer.View.Center = new PointF (gestureRecognizer.View.Center.X + (translation.X/factor), gestureRecognizer.View.Center.Y + (translation.Y/factor));
