Remarks
The UIMenuController is a singleton object, accessed by SharedMenuController. It manages the editng menu, which provides options for Cut, Copy, Paste, Select, Select All, and Delete commands. The menu is visually associated with a target rectangle specified by SetTargetRect(CGRect, UIView). It is the application developer's responsibility to set this target rectangle appropriately before displaying the UIMenuController.
The application can add or delete additional menu items using the MenuItems. The following code, taken from the "Touches Gesture Recognizers" sample shows the code necessary to create a modified context menu:
void Setup ()
{
var menuController = UIMenuController.SharedMenuController;
var resetMenuItem = new UIMenuItem ("Reset", new Selector ("ResetImage"));
var location = gestureRecognizer.LocationInView (gestureRecognizer.View);
BecomeFirstResponder ();
menuController.MenuItems = new [] { resetMenuItem };
menuController.SetTargetRect (new CGRect (location.X, location.Y, 0, 0), gestureRecognizer.View);
menuController.MenuVisible = true;
menuController.Animated = true;
imageForReset = gestureRecognizer.View;
}
...
[Export("ResetImage")]
void ResetImage (UIMenuController controller)
{
var mid = new CGPoint ((imageForReset.Bounds.Left + imageForReset.Bounds.Right) / 2, (imageForReset.Bounds.Top + imageForReset.Bounds.Bottom) / 2);
var locationInSuperview = imageForReset.ConvertPointToView (mid, imageForReset.Superview);
imageForReset.Layer.AnchorPoint = new CGPoint (0.5f, 0.5f);
imageForReset.Center =locationInSuperview;
UIView.BeginAnimations (null, IntPtr.Zero);
imageForReset.Transform = MonoTouch.CoreGraphics.CGAffineTransform.MakeIdentity ();
UIView.CommitAnimations ();
}
