我在 xcode 4.6 中遇到问题。

MainStoryboard 包含一个 Button 和 TableView。显然，当我运行应用程序并单击按钮时，表格视图仅显示第一列和最后一列数据。

我正在使用 sqlite3，我在其中创建了一个数据库和表，该表当前具有一行由 14 列组成的数据。第一列是您信息的主键。

下面是我的 UITableViewCell 代码 * 操作按钮。

任何见解将不胜感激。

谢谢。

-(UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath { static NSString *CellIdentifier = @"Cell"; UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier];

if (!cell) {
    cell = [[UITableViewCell alloc]initWithStyle:UITableViewCellStyleSubtitle reuseIdentifier:CellIdentifier];
}

DefenseStats *aDefenseStats = [arrayOfDefenseStats objectAtIndex:indexPath.row];

cell.textLabel.text = aDefenseStats.defense_team_name_mp;
cell.detailTextLabel.text = [NSString stringWithFormat:@"%d",aDefenseStats.defense_games_mp];
cell.detailTextLabel.text = [NSString stringWithFormat:@"%.2f",aDefenseStats.defense_points_per_game_mp];
cell.detailTextLabel.text = [NSString stringWithFormat:@"%.2f",aDefenseStats.defense_yards_per_game_mp];
cell.detailTextLabel.text = [NSString stringWithFormat:@"%.2f",aDefenseStats.defense_rushing_yards_per_game_mp];
cell.detailTextLabel.text = [NSString stringWithFormat:@"%.2f",aDefenseStats.defense_passing_yards_per_game_mp];
cell.detailTextLabel.text = [NSString stringWithFormat:@"%d",aDefenseStats.defense_interception_mp];
cell.detailTextLabel.text = [NSString stringWithFormat:@"%d",aDefenseStats.defense_interception_touchdown_mp];
cell.detailTextLabel.text = [NSString stringWithFormat:@"%d",aDefenseStats.defense_forced_fumble_mp];
cell.detailTextLabel.text = [NSString stringWithFormat:@"%d",aDefenseStats.defense_defensive_touchdown_mp];
cell.detailTextLabel.text = [NSString stringWithFormat:@"%d",aDefenseStats.defense_tackle_mp];
cell.detailTextLabel.text = [NSString stringWithFormat:@"%d",aDefenseStats.defense_pass_deflection_mp];
cell.detailTextLabel.text = [NSString stringWithFormat:@"%d",aDefenseStats.defense_sack_mp];

return cell;

由于您cell.detailTextLabel.text一遍又一遍地分配到同一个位置 ( )，因此只有最后一个会计算在内。这就是为什么您只看到最后一列的原因。

cell.detailTextLabel.text = [NSString stringWithFormat:@"%d",aDefenseStats.defense_sack_mp];

我认为您真正想要的是每列的一个单元格。您将通过以下方式获得：

- (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section
{
  return 14;
}

然后更新您的tableView:cellForRowAtIndexPath:方法以选择适当的列值，可能使用 14-caseswitch语句并将值分配给cell.textLabel.text：

NSString *defenseStatValue;
switch (indexPath.row)
{
  case (0):
    defenseStatValue = aDefenseStats.defense_team_name_mp;
    break;
  case (1):
    defenseStatValue = [NSString stringWithFormat:@"%d",aDefenseStats.defense_games_mp];
    break;
  /* Add a case for each column index possible. */
}
cell.textLabel.text = defenseStatValue;

另外，不要将任何内容分配给cell.detailTextLabel.text.
