ios - 自定义单元格按钮标签始终返回零

Question

几天来我遇到了一个问题。问题是我有一个包含多个自定义表格单元格的表格，每个单元格都有多个按钮。但我总是将标签值设为零。下面是我的代码

- (UITableViewCell *)tableView:(UITableView *)table cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
    CuatomCell_Contacts *cell    =   (CuatomCell_Contacts *) [tableView dequeueReusableCellWithIdentifier:@"cellA"];
    if  (cell == nil)
    {
        NSArray *topLevelObjects            =   [[NSBundle mainBundle] loadNibNamed:@"CuatomCell_Contacts" owner:Nil options:nil];

        for (id currentObject in topLevelObjects)
        {
            if  ([currentObject isKindOfClass:[UITableViewCell class]])
            {
                cell =  (CuatomCell_Contacts *) currentObject;

                break;
            }
        }
    }
    cell.selectionStyle=UITableViewCellSelectionStyleNone;
    cell.accessoryType = UITableViewCellAccessoryNone;
    IstructContacts *ObjIstructContacts = nil;
    if (table == self.searchDisplayController.searchResultsTableView)
    {
        ObjIstructContacts = [self.filteredListContent objectAtIndex:indexPath.row];
    }
    else
    {
        ObjIstructContacts = [self.sectionedListContent objectAtIndexPath:indexPath];
    }

    cell.m_CtrlLblName.text = ObjIstructContacts.m_strName;
    //cell.m_CtrlLblContact_Id.text=ObjIstructContacts.m_strContact_Id;
    NSLog(@"%@",ObjIstructContacts.m_strImageUrl);
    if ([ObjIstructContacts.m_strImageUrl isEqualToString:@"No_image"])
    {
        cell.m_CtrlImgImage.image=[UIImage imageNamed:@"Person_Dumy.jpeg"];
    }
    else
    {
        NSData * imageData = [[NSData alloc] initWithContentsOfURL: [NSURL URLWithString: ObjIstructContacts.m_strImageUrl]];

        cell.m_CtrlImgImage.image=[UIImage imageWithData: imageData];
    }
    cell.M_CtrlBtnChat.tag=indexPath.row;
    [cell.M_CtrlBtnChat addTarget:self action:@selector(MoveToNextView:) forControlEvents:UIControlEventTouchUpInside];
    UIButton *button = [UIButton buttonWithType:UIButtonTypeRoundedRect];
    [button addTarget:self
               action:@selector(MoveToNextView:)
     forControlEvents:UIControlEventTouchDown];
    [button setTitle:@"Custom Action" forState:UIControlStateNormal];
    button.frame = CGRectMake(150.0f, 5.0f, 150.0f, 30.0f);
    button.tag=indexPath.row;
    [cell.contentView addSubview:button];

    return cell;
}



-(void)MoveToNextView:(id)sender
{
    UIButton *button = (UIButton *)sender;

    NSLog(@"Tag Value = %d",button.tag);
}

标记值始终返回零。在静态和动态按钮操作中。

试试这个方法，更简洁的方法来查找 View 的封闭行。

 -(IBAction)cellButtonTapped:(id)sender {
    UIButton *button = sender;
    CGPoint correctedPoint = [button convertPoint:button.bounds.origin toView:self.tableview];
    NSIndexPath *indexPath = [self.tableView indexPathForRowAtPoint:correctedPoint];
    NSLog(@"Button tapped in row %d",indexPath.row);
    }
