隐藏UIMenuController显示“粘贴”，“选择”，“全选”

Question

I am developing an app that supports IM. Below is a UITextField , up is a UITableView displaying historial messages in bubbles（ UIView ）. Bubble has add longPressGesture , UIMenuController is called by the longPressGesture. My problem is when the textField is firstResponder ,the keyboad is showing, then UIMenuController is called by longPressGesture, normally it works fine. But if there is text in the textField,the menuController show more items than I expected,like "select","selectAll".

Here belows is my code:

-(BOOL)canPerformAction:(SEL)action withSender:(id)sender {
    if (action == @selector(copyMenuAction:)||
        action == @selector(deleteMenuAction:)||
        action == @selector(resendMenuAction:)||
        action == @selector(forwardMenuAction:))
    {
        return YES;
    }
   //    else if (action == @selector(cut:)||
   //             action == @selector(copy:)||
   //             action == @selector(paste:))
   //    {
   //        return NO;
   //    }
    else
        return [super canPerformAction:action withSender:sender];

    return  NO;
   }

  -(BOOL) canBecomeFirstResponder{
    return YES;
   }

Answer 1

Try to add gesture recogniser only in UITableView .

UILongPressGestureRecognizer *longGes = [[UILongPressGestureRecognizer alloc] 
  initWithTarget:self action:@selector(handleLongPress:)];
longGes.minimumPressDuration = 2.0; //seconds
longGes.delegate = self;
[self.tableView addGestureRecognizer: longGes];

Then in the gesture handler:

-(void)handleLongPress:(UILongPressGestureRecognizer *)gestureRecognizer
{
    CGPoint p = [gestureRecognizer locationInView:self.tableView];

    NSIndexPath *indexPath = [self.myTableView indexPathForRowAtPoint:p];
    if (indexPath == nil) {
        NSLog(@"long press on table view but not on a row");
    }
    else { 
        if (gestureRecognizer.state == UIGestureRecognizerStateBegan) {
            NSLog(@"long press on table view at row %d", indexPath.row);
        }
        else {
            NSLog(@"gestureRecognizer.state = %d", gestureRecognizer.state);
        }
    }
}

Hope this helps.. :)
