示例1: TouchesMoved
public override void TouchesMoved (NSSet touches, UIEvent evt)
{
CanvasView.DrawTouches (touches, evt);
var touch = (UITouch)touches.FirstOrDefault ();
if (touch == null)
return;
UpdateReticleView (touch);
// Use the last predicted touch to update the reticle.
UITouch[] predictedTouches = evt?.GetPredictedTouches (touch);
UITouch predictedTouch = predictedTouches?.LastOrDefault ();
if (predictedTouch != null)
UpdateReticleView (predictedTouch, true);
}示例2: TouchesBegan

{
if (trackedTouch == null) {
trackedTouch = (UITouch)touches.FirstOrDefault ();
initialTimestamp = trackedTouch.Timestamp;
if (!IsForPencil)
BeginIfNeeded (null);
fingerStartTimer = NSTimer.CreateScheduledTimer (cancellationTimeInterval, BeginIfNeeded);
}
if (Append (Touches(touches), evt)) {
if (IsForPencil)
State = Began;
}
