当我 uitableviewcell 滑动时调用 didSelectRowAtIndexPath

Question

我在我的应用程序中使用 ABMenuTableViewCell tableview controller。我想在滑动单元格时调用 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];
   }

这些是单元格 class 中的方法 - (BOOL)gestureRecognizerShouldBegin:(UIGestureRecognizer *)gestureRecognizer 和 - (void)swipeGesture:(UIPanGestureRecognizer *)gesture 和 UIPanGestureRecognizer *_swipeGesture;

Answer 1

您需要在 UITableView 上应用手势并使用 indexPathForRowAtPoint 找出单元格。

Answer 2

您需要添加 UISwipeGesture。你可以通过两种方式实现。将 UISwipeGesture 添加到 UITableViewCell 或 UITableView。在这里我只解释在 UITableView 上添加 UISwipeGesture 因为在这种情况下你需要添加 UISwipeGesture 一次。

如何在UITableView中添加UISwipeGesture。

//Add a left swipe gesture recognizer
    UISwipeGestureRecognizer *recognizer = [[UISwipeGestureRecognizer alloc] initWithTarget:self
                                                                                  action:@selector(didSwipe:)];
    [recognizer setDirection:(UISwipeGestureRecognizerDirectionLeft)];
    [self.tableView addGestureRecognizer:recognizer];
    [recognizer release];

    //Add a right swipe gesture recognizer
    recognizer = [[UISwipeGestureRecognizer alloc] initWithTarget:self
                                                        action:@selector(didSwipe:)];
    recognizer.delegate = self;
    [recognizer setDirection:(UISwipeGestureRecognizerDirectionRight)];
    [self.tableView addGestureRecognizer:recognizer];
    [recognizer release];

这里是UISwipeGestureRecognizer的选择器方法。你有 indexPath 的地方会给你 index 的 Image Array.

-(void)didSwipe:(UIGestureRecognizer *)gestureRecognizer {

  if (gestureRecognizer.state == UIGestureRecognizerStateEnded) {
        CGPoint swipeLocation = [gestureRecognizer locationInView:self.tableView];
        NSIndexPath *swipedIndexPath = [self.tableView indexPathForRowAtPoint:swipeLocation];


        [imageArray removedObjectAtIndexPath:swipedIndexPath.row];
        [tableView reloadData];
  }

这里我认为 imageArray 是你的 array of images.

希望对您有所帮助。
