当我点击我的表格视图中的第一个单元格时didSelectRowAtIndexPath没有触发......有没有人看起来和/或对为什么会发生这种情况有任何线索?我表中的所有其他单元格都可以正常工作,如果点击第一个单元格,我在didSelectRowAtIndexPath应用程序的代码中设置断点不会进入该代码,但如果点击任何其他单元格,则会进入代码。这是一些代码:

    - (NSInteger)tableView:(UITableView *)tableView indentationLevelForRowAtIndexPath:(NSIndexPath *)indexPath
{
    NSInteger row = 0;
    return row;
}

- (NSIndexPath *)tableView:(UITableView *)tableView willSelectRowAtIndexPath:(NSIndexPath *)indexPath
{
    NSInteger row = [indexPath row];
    if (row == 0)
        return nil;

    return indexPath;
}

- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath
{
    //NSUInteger row = [indexPath row];
    //NSString *rowValue = [poolListData objectAtIndex:row];

    int newRow = [indexPath row];
    int oldRow = [lastIndexPathForPoolList row];

    if (newRow != oldRow)
    {
        UITableViewCell *newCell = [tableView cellForRowAtIndexPath:indexPath];
        newCell.accessoryType = UITableViewCellAccessoryCheckmark;

        UITableViewCell *oldCell = [tableView cellForRowAtIndexPath: lastIndexPathForPoolList]; 
        oldCell.accessoryType = UITableViewCellAccessoryNone;

        lastIndexPathForPoolList = indexPath;   
    }

    [tableView deselectRowAtIndexPath:indexPath animated:YES];
}

- (NSInteger)tableViewForDelete:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section
{
    return [poolListData count];
}

- (UITableViewCell *)tableViewtableViewForDelete:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{

    static NSString *DeleteMeCellIdentifier = @"DeleteMeCellIdentifier";

    UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:DeleteMeCellIdentifier];
    if (cell == nil)
    {
        cell = [[[UITableViewCell alloc] initWithFrame:CGRectZero reuseIdentifier:DeleteMeCellIdentifier] autorelease];
    }

    NSInteger row = [indexPath row];
    cell.text = [self.poolListData objectAtIndex:row];
    return cell;
}

- (CGFloat)tableView:(UITableView *)tableView heightForRowAtIndexPath:(NSIndexPath *)indexPath
{
    return 50;
}

- (void)tableView:(UITableView *)tableView commitEditingStyle:(UITableViewCellEditingStyle)editingStyle forRowAtIndexPath:(NSIndexPath *)indexPath
{   
    NSUInteger row = [indexPath row];
    [self.poolListData removeObjectAtIndex:row];
    [tableView deleteRowsAtIndexPaths:[NSArray arrayWithObject:indexPath] withRowAnimation:UITableViewRowAnimationFade];
}

感谢您的宝贵时间和您能给我的任何帮助!

我认为您在第一行的 willSelectRowForIndexPath 中返回 nil。这将防止该行被选中。
