ios - 点击单元格时从 uitableviewcell 类调用 uipangesture

Question

我正在使用 ABMenuTableViewCell我的应用程序中的 TableView Controller 。我想在滑动 UITableViewCell 时调用 didSelectRowAtIndexPath。

现在 didSelectRowAtIndexPath 只在我点击一个单元格时执行，即使我滑动它我也想调用它。这是我的 didSelectRowAtIndexPath 和 cellforRowAtIndexPath 方法代码。

- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
        UILabel *likes;
        UILabel *downloads;
        static NSString *CellIdentifier = @"Cell";
        ABMenuTableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier];

        if (cell == nil)
        {
            cell = [[ABMenuTableViewCell alloc] initWithStyle:UITableViewCellStyleSubtitle reuseIdentifier:CellIdentifier];
            arrow = [[UIImageView alloc] initWithImage:[UIImage imageNamed:@"acc_arrow_back.png"]];
            arrow.frame = CGRectMake(300, 50, 5, 12);
            arrow.image = [arrow.image imageWithRenderingMode:UIImageRenderingModeAlwaysTemplate];
            [arrow setTintColor:[UIColor colorWithRed:(191/255.0) green:(2/255.0) blue:(6/255.0) alpha:1]];
            [cell.contentView addSubview:arrow];

UIImageView *likes_img = [[UIImageView alloc] initWithImage:[UIImage imageNamed:@"social.png"]];
            likes_img.frame = CGRectMake(15, 80, 15, 15);
            likes_img.image = [likes_img.image imageWithRenderingMode:UIImageRenderingModeAlwaysTemplate];
            [likes_img setTintColor:[UIColor colorWithRed:(191/255.0) green:(2/255.0) blue:(6/255.0) alpha:1]];
            [cell.contentView addSubview:likes_img];

            likes =[[UILabel alloc]initWithFrame:CGRectMake(33, 78, 80, 20)];
            likes.tag = 1001;    // set a tag for this View so you can get at it later
            likes.textColor=[UIColor darkGrayColor];
            likes.font=[UIFont fontWithName:@"Helvetica" size:10.0f];
            likes.text=[[rssOutputData objectAtIndex:indexPath.row]xmllikes];
            [cell.contentView addSubview:likes];
            cell.detailTextLabel.textColor = [UIColor darkGrayColor];

            UIImageView *downloads_img = [[UIImageView alloc] initWithImage:[UIImage imageNamed:@"download.png"]];
            downloads_img.frame = CGRectMake(55, 79, 15, 15);
            downloads_img.image = [downloads_img.image imageWithRenderingMode:UIImageRenderingModeAlwaysTemplate];
            [downloads_img setTintColor:[UIColor colorWithRed:(191/255.0) green:(2/255.0) blue:(6/255.0) alpha:1]];
            [cell.contentView addSubview:downloads_img];

            downloads =[[UILabel alloc]initWithFrame:CGRectMake(73, 78, 80, 20)];
            downloads.tag = 1002;    // set a tag for this View so you can get at it later
            downloads.textColor=[UIColor darkGrayColor];
            downloads.font=[UIFont fontWithName:@"Helvetica" size:10.0f];
            downloads.text=[[rssOutputData objectAtIndex:indexPath.row]xmldownloads];
            [cell.contentView addSubview:downloads];
            cell.detailTextLabel.textColor = [UIColor darkGrayColor];
        }
        else
        {
            // use viewWithTag to find lblNombre in the re-usable cell.contentView
            likes = (UILabel *)[cell.contentView viewWithTag:1001];
            downloads = (UILabel *)[cell.contentView viewWithTag:1002];

        }
        cell.textLabel.text = [[rssOutputData objectAtIndex:indexPath.row]xmlsinger];
        cell.detailTextLabel.text = [[rssOutputData objectAtIndex:indexPath.row]xmltitle];
        // custom menu view
        NSString *nibName = @"ABCellMailStyleMenuView";
        ABCellMenuView *menuView = [ABCellMenuView initWithNib:nibName bundle:nil];
        menuView.delegate = self;
        menuView.indexPath = indexPath;
        cell.rightMenuView = menuView;
        return cell;
}


   - (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath
   {
            [tableView deselectRowAtIndexPath:indexPath animated:YES];
   }

这些是单元类 中的方法
- (BOOL)gestureRecognizerShouldBegin:(UIGestureRecognizer *)gestureRecognizer 和- (void)swipeGesture:(UIPanGestureRecognizer *)gesture这是我滑动的时候

Answer 1

您可以修改 swipeGesture 方法将跟随代码。执行滑动操作后，它会将 UITableViewCell 显示为 selected。

- (void)swipeGesture:(UIPanGestureRecognizer *)gesture {
    if (gesture.state == UIGestureRecognizerStateBegan) {
        NSInteger direction;

        // find swipe direction
        CGPoint velocity = [gesture velocityInView:self];
        if (velocity.x > 0) {
            // towards right - hide menu view
            direction = ABMenuUpdateHideAction;
        }
        else {
            // towards left - show menu view
            direction = ABMenuUpdateShowAction;
        }


        UITableView* tableView = (UITableView*)self.superview.superview;

        CGPoint swipeLocation = [gesture locationInView:tableView];
        NSIndexPath *swipedIndexPath = [tableView indexPathForRowAtPoint:swipeLocation];

        [tableView selectRowAtIndexPath:swipedIndexPath animated:NO scrollPosition:UITableViewScrollPositionNone];


        [self updateMenuView:direction animated:YES];
    }
}

希望对你有帮助。
