Estou usando umUIMenuItem para executar uma ação personalizada emUICollectionView imprensa longa da pilha. isso funcionou perfeitamente com o iOS 6, mas agora estou convertendo meu aplicativo para iOS 7 e Xcode 5 e não funciona. O item personalizado não é mostrado.

UIMenuItem *menuItem = [[UIMenuItem alloc] initWithTitle:@"Unfavorite"
                                                  action:@selector(unFavorite:)];
[[UIMenuController sharedMenuController] setMenuItems:[NSArray arrayWithObject:menuItem]];
[UIMenuController sharedMenuController].menuVisible = YES;

- (BOOL)collectionView:(UICollectionView *)collectionView canPerformAction:(SEL)action forItemAtIndexPath:(NSIndexPath *)indexPath withSender:(id)sender;
{
    //do not show default itens like copy, paste....
    [self becomeFirstResponder];
    return NO;
}


- (BOOL)canPerformAction:(SEL)action withSender:(id)sender {
// The selector(s) should match your UIMenuItem selector
    if (action == @selector(unFavorite:)) {
         return YES;
    }
    return NO;
}

- (void)collectionView:(UICollectionView *)collectionView
     performAction:(SEL)action
forItemAtIndexPath:(NSIndexPath *)indexPath
        withSender:(id)sender {

}

 - (BOOL)collectionView:(UICollectionView *)collectionView
 shouldShowMenuForItemAtIndexPath:(NSIndexPath *)indexPath {

    myIndexPath = indexPath;
    return YES;
}
