iphone - このコードでクラッシュするエラーは何ですか?

Question

カスタムセルで10行のテーブルを表示し、1つは通常のセルで表示するテーブルビューを使用しています。私はこのコードを使用しています...

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


    static NSString *CellIdentifier=@"Cell";
    UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier];
    if (indexPath.row == [listofBusiness count]) {

        if (cell == nil) {
            cell = [[[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:CellIdentifier] autorelease];
            }

    cell.textLabel.text= @"Show more...";
    //cell = self.tvcell;
    return cell;

}

else if(indexPath.row==[appDelegate.busines_Aray count])
{

    if (cell == nil) {
        cell = [[[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:CellIdentifier] autorelease];
    }

    return cell;

}

if(customCell == nil) {
    [[NSBundle mainBundle] loadNibNamed:@"Place_cell" owner:self options:nil];
}


// Configure the cell...


    cell.backgroundColor=[UIColor colorWithRed:0.92 green:0.92 blue:0.92 alpha:1];
    cell.accessoryType = UITableViewCellAccessoryNone;
    cell.selectionStyle=UITableViewCellSelectionStyleNone;
    BusinessData *business_datas = [appDelegate.busines_Aray objectAtIndex:indexPath.row];  
    UITextField *tmptxt;
    tmptxt = (UITextField *)[cell viewWithTag:1];
    tmptxt.backgroundColor=[UIColor clearColor];
    tmptxt.text = [NSString stringWithFormat:@"%@",business_datas.name_business ];
    tmptxt = (UITextField *)[cell viewWithTag:2];
    tmptxt.text = [NSString stringWithFormat:@"%@", business_datas.cat_business];

Answer 1

2 つの異なるタイプのセルを使用している場合は、2 つの再利用識別子を使用する必要があります。

それが何でcustomCellあるか、またはいつそれが何かに設定されるかは明らかではありません。

常に新しいイメージ ビューをインスタンス化して追加する必要はありません。これにより、互いの上に複数の画像ビューを持つ再利用セルが作成されます。イメージ ビューは、最初にセルをインスタンス化するときに追加し、再利用するときに構成する必要があります。星の評価を表示するために 5 つの画像ビューを使用しているように見えますが、Unicode の星の文字を使用すると思われるテキストでこれを実現できます。

コードのセクションに到達しているため、コードがクラッシュしています//Configure the cell...。この時点cellではnilです。オブジェクトnilを返す必要があるため、例外が発生する原因となっています。UITableViewCell

ドキュメントでセル再利用機能を調べて、そこにパターンを適用します。それは非常に簡単です：

• に基づいて再利用識別子を決定しますindexPath
• その識別子でセルのデキューを試みます
• 何も返されない場合は、セルを作成するか、ペン先からロードして、この時点でサブビューを作成します
• デキューされたセルまたは新しく作成されたセルのセルとサブビューを構成します
• 完成したセルを返す
