示例1: CornerOfRect
ControlCorner CornerOfRect (CGRect rect, CGPoint point)
{
var closestDistance = nfloat.MaxValue;
var closestCorner = ControlCorner.None;
Tuple<ControlCorner, CGPoint> [] corners = {
Tuple (ControlCorner.TopLeft, rect.CornerTopLeft()),
Tuple (ControlCorner.TopRight, rect.CornerTopRight ()),
Tuple (ControlCorner.BottomLeft, rect.CornerBottomLeft ()),
Tuple (ControlCorner.BottomRight, rect.CornerBottomRight())
};
// corner, cornerPoint
foreach (var tpl in corners) {
var corner = tpl.Item1;
var cornerPoint = tpl.Item2;
var dX = point.X - cornerPoint.X;
var dY = point.Y - cornerPoint.Y;
var distance = NMath.Sqrt ((dX * dX) + (dY * dY));
if (distance < closestDistance) {
closestDistance = distance;
closestCorner = corner;
}
}
