Question

我使用以下代码获取被点击的tablecell的索引。

- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath;
{
    tabBar = [self.storyboard instantiateViewControllerWithIdentifier:@"TabBarController"];
    [self.navigationController pushViewController:tabBar animated:YES];
    [tableView deselectRowAtIndexPath:indexPath animated:YES];
    [tableView setAllowsSelection:YES];

    NSLog(@"you have selected %d",indexPath.row);
}

此代码的问题是它只打印一次row的索引值。如果我再次点击tableviews，它不会打印索引值。如何知道我点击了哪个索引？

Answer 1

试试这个

- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath;
{
     NSLog(@"you have selected %d",indexPath.row);
      [tableView deselectRowAtIndexPath:indexPath animated:YES];
    [tableView setAllowsSelection:YES];
    tabBar = [self.storyboard instantiateViewControllerWithIdentifier:@"TabBarController"];
    [self.navigationController pushViewController:tabBar animated:YES];

}

Answer 2

-(void) tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath
{
    [tableView deselectRowAtIndexPath:indexPath animated:YES];
    UITableViewCell * tableCell = [tableView cellForRowAtIndexPath:indexPath];
    BOOL isSelected = (tableCell.accessoryType == UITableViewCellAccessoryCheckmark);
    if (isSelected)
    {
        tableCell.accessoryType = UITableViewCellAccessoryNone;

    }
    else
    {
        tableCell.accessoryType = UITableViewCellAccessoryCheckmark;
    }
}

现在检查附件检查标记何时出现它是否会打印索引路径??

uitableview不会为每次点击
