ios - How do you REALLY remove Copy from UIMenuController

Question

There apparently used to be an easy way to prevent the "More..." label from appearing in UIMenuController when you added more than one custom menu item. You just had to remove all of the system menu items. There was even a workaround here for still having copy work. You just had to implement a custom copy command using a different selector and then override canPerformAction:withSender: to not show the system copy:

-(BOOL)canPerformAction:(SEL)action withSender:(id)sender 
{
    if (action == @selector(copy:))
       return NO;
    else
       // logic to show or hide other things
}

Unfortunately this method no longer works (at least in a UIWebView subclass). canPerformAction:withSender: is called for every system menu item except copy: so the result is that the system copy menu item is always displayed. This means that if you have more than one custom menu item, they are always hidden behind "More..."

So, is there a way to really remove the system's copy item or some alternate way to prevent menu items from hiding behind "More..."?

Update

This is the output I get when I override canPerformAction:withSender: notice that the method is never called for the "copy:" action:

Answer 1

The technique you linked to still seems to work. I implemented a UIWebView subclass with these methods, and only the A and B items appeared.

+ (void)initialize
{
    UIMenuItem *itemA = [[UIMenuItem alloc] initWithTitle:@"A" action:@selector(a:)];
    UIMenuItem *itemB = [[UIMenuItem alloc] initWithTitle:@"B" action:@selector(b:)];
    [[UIMenuController sharedMenuController] setMenuItems:[NSArray arrayWithObjects:itemA, itemB, nil]];
    [itemA release];
    [itemB release];
}

- (BOOL)canPerformAction:(SEL)action withSender:(id)sender
{
    BOOL can = [super canPerformAction:action withSender:sender];
    if (action == @selector(a:) || action == @selector(b:))
    {
        can = YES;
    }
    if (action == @selector(copy:))
    {
        can = NO;
    }
    NSLog(@"%@ perform action %@ with sender %@.", can ? @"can" : @"cannot", NSStringFromSelector(action), sender);
    return can;
}
