DetailTextLabelがUITableViewCellで変更を続ける

Question

各セクションのキーを含む3つのNSArraysから3つのセクションを取り出すUITableViewをセットアップしました。各セルのdetailTextLabelsとアクセサリビューを手動で設定するswitch文を設定しようとしましたが、テーブルビューをスクロールするたびにセルが一見して変わってしまいます。これを行うより効率的な方法はありますか？

これは私が使用してみました一つの方法である：

switch (indexPath.section) 
{ 
    // info 
    case 0:{ 
     cell.textLabel.text = [infoKeysArray objectAtIndex:indexPath.row]; 
     if ([cell.textLabel.text isEqualToString:@"Duration"]) 
     { 
      cell.detailTextLabel.text = [task stringForDuration]; 
     } 
     if ([cell.textLabel.text isEqualToString:@"Elapsed"]) 
     { 
      // elapsed time 
     } 
     if ([cell.textLabel.text isEqualToString:@"Today"]) 
     { 
      UISwitch *todaySwitch = [[UISwitch alloc] initWithFrame:CGRectZero]; 
      [todaySwitch addTarget:self action:@selector(todaySwitchValueChanged:) forControlEvents:UIControlEventValueChanged]; 
      [todaySwitch setOn:task.isToday]; 
      cell.accessoryView = todaySwitch; 
      [todaySwitch release]; 
     } 
    } 
     break; 
    // actions 
    case 1:{ 
     cell.textLabel.text = [actionsKeysArray objectAtIndex:indexPath.row]; 
     if ([cell.textLabel.text isEqualToString:@"Priority"]) 
     { 
      // priority 
      [cell setAccessoryType:UITableViewCellAccessoryDisclosureIndicator]; 
     } 
     if ([cell.textLabel.text isEqualToString:@"Finish Early"]) 
     { 
      // finish early 
     } 
     if ([cell.textLabel.text isEqualToString:@"Set New Time"]) 
     { 
      [cell setAccessoryType:UITableViewCellAccessoryDisclosureIndicator]; 
     } 
     if ([cell.textLabel.text isEqualToString:@"Repeating"]) 
     { 
      UISwitch *repeatingSwitch = [[UISwitch alloc] initWithFrame:CGRectZero]; 
      [repeatingSwitch addTarget:self action:@selector(repeatingSwitchValueChanged:) forControlEvents:UIControlEventValueChanged]; 
      [repeatingSwitch setOn:task.isRepeating]; 
      cell.accessoryView = repeatingSwitch; 
      [repeatingSwitch release]; 
      //cell.detailTextLabel.text = nil; 
     } 
    } 
     break; 
    // details 
    case 2:{ 
     cell.textLabel.text = [detailsKeysArray objectAtIndex:indexPath.row]; 
     if ([cell.textLabel.text isEqualToString:@"Specifics"]) 
     { 
      cell.detailTextLabel.text = task.specifics; 
      [cell setAccessoryType:UITableViewCellAccessoryDisclosureIndicator]; 
     } 
     if ([cell.textLabel.text isEqualToString:@"Repeated"]) 
     { 
      // times repeated 
     } 
    } 
     break; 
    default: 
     break; 
} 

そして、これは別です：

// Info section 
if ([indexPath section] == 0) 
{ 
    // duration 
    cell.textLabel.text = [infoKeysArray objectAtIndex:indexPath.row]; 
    if (indexPath.row == 0) 
    { 
     cell.detailTextLabel.text = [task stringForDuration]; 
    } 
    // elapsed time 
    if (indexPath.row == 1) 
    { 
     //cell.detailTextLabel.text = [task stringForTotalElapsedTime]; 
    } 
    // today status 
    if (indexPath.row == 2) 
    { 
     UISwitch *todaySwitch = [[UISwitch alloc] initWithFrame:CGRectZero]; 
     [todaySwitch addTarget:self action:@selector(todaySwitchValueChanged:) forControlEvents:UIControlEventValueChanged]; 
     [todaySwitch setOn:task.isToday]; 
     cell.accessoryView = todaySwitch; 
     [todaySwitch release]; 

    } 
} 
// actions section 
if ([indexPath section] == 1) 
{ 
    cell.textLabel.text = [actionsKeysArray objectAtIndex:indexPath.row]; 
    // priority 
    if (indexPath.row == 0) 
    { 
     [cell setAccessoryType:UITableViewCellAccessoryDisclosureIndicator]; 
    } 
    // finish early 
    if (indexPath.row == 1) 
    { 
     //[cell setAccessoryType:UITableViewCellAccessoryDisclosureIndicator]; 
    } 
    // set new time 
    if (indexPath.row == 2) 
    { 
     //cell.accessoryView = repeatingSwitch; 
     [cell setAccessoryType:UITableViewCellAccessoryDisclosureIndicator]; 
    } 
    // repeating 
    if (indexPath.row == 3) 
    { 
     UISwitch *repeatingSwitch = [[UISwitch alloc] initWithFrame:CGRectZero]; 
     [repeatingSwitch addTarget:self action:@selector(repeatingSwitchValueChanged:) forControlEvents:UIControlEventValueChanged]; 
     [repeatingSwitch setOn:task.isRepeating]; 
     cell.accessoryView = repeatingSwitch; 
     [repeatingSwitch release]; 
     cell.detailTextLabel.text = nil; 
    } 
} 
// details section 
if ([indexPath section] == 2) 
{ 
    cell.textLabel.text = [detailsKeysArray objectAtIndex:indexPath.row]; 
    // specifics 
    if (indexPath.row == 0) 
    { 
     //cell.detailTextLabel.text = taskDetails.specifics; 
     cell.detailTextLabel.text = task.specifics; 
     [cell setAccessoryType:UITableViewCellAccessoryDisclosureIndicator]; 
    } 
    // repeated 
    if (indexPath.row == 1) 
    { 
     [cell setAccessoryView:nil]; 
    } 
} 

これらの試みの両方が、私はこの質問を自分で解決することになったcellForRowAtIndexPath

の内側にあったが、 @ Tillのコメントに全面的に感謝します。すでに存在するセルを再利用することにより、UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier]の作業が行われるようです。したがって、テーブル内で複数のセルタイプを使用するには、異なる再利用識別子を使用する必要があります。それとも、私が唯一の7つのまたは8テーブルビューセルを持っているので、私はちょうど私がUISwitchを含まないようにしたいすべてのセルのnilにセルアクセサリビューを設定し、そのよう：

[cell setAccessoryType:UITableViewCellAccessoryNone]; 

switch ([indexPath section]) 
{ 
    case 0: 
    { 
     cell.textLabel.text = [infoKeysArray objectAtIndex:indexPath.row]; 
     switch (indexPath.row) { 
      case 0: 
      { 
       cell.detailTextLabel.text = task.stringForDuration; 
       [cell setAccessoryType:UITableViewCellAccessoryDisclosureIndicator]; 
       cell.accessoryView = nil; 
      } 
       break; 
      case 1: 
      { 
       cell.detailTextLabel.text = @"00:00"; 
       [cell setAccessoryType:UITableViewCellAccessoryNone]; 
       cell.accessoryView = nil; 
      } 
       break; 
      case 2: 
      { 
       UISwitch *todaySwitch = [[UISwitch alloc] initWithFrame:CGRectZero]; 
       [todaySwitch addTarget:self action:@selector(todaySwitchValueChanged:) forControlEvents:UIControlEventValueChanged]; 
       [todaySwitch setOn:task.isToday]; 
       cell.accessoryView = todaySwitch; 
       [todaySwitch release]; 
       [cell setAccessoryType:UITableViewCellAccessoryNone]; 
       cell.detailTextLabel.text = @""; 
      } 
       break; 
      default: 
       break; 
     } 
    } 
     break; 
    case 1: 
    { 
     cell.textLabel.text = [actionsKeysArray objectAtIndex:indexPath.row]; 
     switch (indexPath.row) { 
      case 0: 
      { 
       cell.detailTextLabel.text = @"Low"; 
       [cell setAccessoryType:UITableViewCellAccessoryDisclosureIndicator]; 
       cell.accessoryView = nil; 
      } 
       break; 
      case 1: 
      { 
       cell.detailTextLabel.text = @""; 
       [cell setAccessoryType:UITableViewCellAccessoryDisclosureIndicator]; 
       cell.accessoryView = nil; 
      } 
       break; 
      case 2: 
      { 
       UISwitch *repeatingSwitch = [[UISwitch alloc] initWithFrame:CGRectZero]; 
       [repeatingSwitch addTarget:self action:@selector(repeatingSwitchValueChanged:) forControlEvents:UIControlEventValueChanged]; 
       [repeatingSwitch setOn:task.isRepeating]; 
       cell.accessoryView = repeatingSwitch; 
       [repeatingSwitch release]; 
       cell.detailTextLabel.text = @""; 
       [cell setAccessoryType:UITableViewCellAccessoryNone]; 
      } 
       break; 
      default: 
       break; 
     } 
    } 
     break; 
    case 2: 
    { 
     cell.textLabel.text = [detailsKeysArray objectAtIndex:indexPath.row]; 
     switch (indexPath.row) { 
      case 0: 
      { 
       cell.detailTextLabel.text = task.specifics; 
       [cell setAccessoryType:UITableViewCellAccessoryDisclosureIndicator]; 
       cell.accessoryView = nil; 
      } 
       break; 
      case 1: 
      { 
       cell.detailTextLabel.text = @"0"; 
       [cell setAccessoryType:UITableViewCellAccessoryNone]; 
       cell.accessoryView = nil; 
      } 
       break; 
      default: 
       break; 
     } 
     break; 
    } 
    default: 
     break; 
}
