UITableView didSelectRowAtIndexPath ，与部分行中显示的值不同！

Question

- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath {

Directory *aDirectory = [appDelegate.directories objectAtIndex:indexPath.row];
    _XMLDetailsView.aDirectory = aDirectory;

if (indexPath.section == 0) // First section
{
    _XMLDetailsView.aDirectory = aDirectory;
}
else if(indexPath.section == 1) // Second Section
{
    Directory *aDirectory = [appDelegate.directories objectAtIndex:indexPath.row +[listOfItems count]];
    _XMLDetailsView.aDirectory = aDirectory;

}
else if(indexPath.section == 2) // Third Section
{
    Directory *aDirectory = [appDelegate.directories objectAtIndex:indexPath.row +[listOfItems count] +3];
    _XMLDetailsView.aDirectory = aDirectory;

}
else if(indexPath.section == 3) // Fourth Section
{
    Directory *aDirectory = [appDelegate.directories objectAtIndex:indexPath.row +[listOfItems count] +9];
    _XMLDetailsView.aDirectory = aDirectory;

}

？

这是从特定部分选择特定行值的正确方法吗 因为当我为例如“C”部分执行SelectRowAtIndexpath时，它应该显示从数组 (4) 开始的值。但在“C”部分，它再次显示 array(0) 中的值。我在这件事上坚持了很长时间，有人有任何建议或帮助吗？

Answer 1

else if(indexPath.section == 2) // Third Section
{

    if(indexPath.row >4)
    {
        Directory *aDirectory = [appDelegate.directories objectAtIndex:indexPath.row +[listOfItems count] +3];
       _XMLDetailsView.aDirectory = aDirectory;
    }
}

试试这个，我想这对你有帮助。

Answer 2

Directory *aDirectory = [appDelegate.directories objectAtIndex:indexPath.row];

该方法开头的语句使用 indexPath.row 选择目录，该目录不会来自正确的部分。尝试使用 indexPath.section 来实现这一点。

 Directory *aDirectory = [appDelegate.directories objectAtIndex:indexPath.section];
