推荐答案

您引用的弹出窗口称为 UIMenuController .您可以访问 [UIMenuController sharedMenuController] 方法以获取菜单控制器.然后，您可以将自己的 UIMenuItems 添加到菜单控制器.

The popup you refer to is called a UIMenuController. You can access the [UIMenuController sharedMenuController] method to get the menu controller. You can then add your own UIMenuItems to the menu controller.

UIMenuItem* myBtn1 = [[[UIMenuItem alloc] initWithTitle: @"Button 1" action:@selector( onButton1: )] autorelease];
UIMenuItem* myBtn2 = [[[UIMenuItem alloc] initWithTitle: @"Button 2" action:@selector( onButton2: )] autorelease];
UIMenuController* mc = [UIMenuController sharedMenuController];
mc.menuItems = [NSArray arrayWithObjects: myBtn1, myBtn2, nil];

现在实现方法

- (void) onButton1: (UIMenuController*) sender
{
}

- (void) onButton2: (UIMenuController*) sender
{
}

修改

您可以实施长手势"

UILongPressGestureRecognizer* gr = [[[UILongPressGestureRecognizer alloc] initWithTarget: self action: @selector( onShowMenu: ) ] autorelease];
   [_myview addGestureRecognizer: gr];



- (void) onShowMenu: (UIGestureRecognizer*) sender
{
    [sender.view becomeFirstResponder];

    UIMenuController* mc = [UIMenuController sharedMenuController];

    CGRect bounds = sender.view.bounds;

    [mc setTargetRect: sender.view.frame inView: sender.view.superview];
    [mc setMenuVisible: YES animated: YES];
}
