カスタム テーブル ビュー セルがあり、2 つの UIButton と、edit および cancel という名前の 1 つのテキスト フィールドと、1 つの textField があります。同時に編集をクリックすると、TextFeild インタラクションが有効になり、キャンセル ボタンの画像が変更されます。私にとってはうまくいきます!!

しかし、編集ボタンをクリックすると、別のセルがキャンセルされます bitton 画像IDが自動的に変更されました! セルを再利用しているので、これが起こっていることを知っています!! しかし、私は解決策を見つけることができません...

次のコードを使用して、古いセルを再利用せずに新しいセルを直接作成します。

cell = [[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:simpleTableIdentifier];

それ以外の

cell = (MenuNameCell *)[tableView dequeueReusableCellWithIdentifier:simpleTableIdentifier];

おい、これはとにかくセルを再利用するためではないと思います。もしあなたが思うなら、すべてのコードをifに保管してください。ただし、クリックイベントでIDを変更するものを確認する必要があります。

もう 1 つ、一般的にこの目的でタグを使用するのが私たちの習慣になっています。ここで、試してみてください：-

* objc_setAssociatedObject*

これにより、常にセルまたは関連するものを参照できます。グーグルだけで、一見すると、下にコードを貼り付けているだけです。チェックしてください:(ただし、要件に従って作業する必要があります)

Now, access your association as :-

    {
        [popTbl isHidden]?[popTbl setHidden:NO]:[popTbl setHidden:YES];
        [popTbl setHidden:NO];
        NSIndexPath* iPath =  nil;
        iPath = objc_getAssociatedObject(sender, SMALL_BTN_REF);
        NSIndexPath* iPathNew = nil;
        iPathNew = objc_getAssociatedObject(sender, SMALL_BTN_REF_1);
        (iPath)?(associateIndex = iPath.row):(associateIndex = iPathNew.row);
        UITextField* tempField = nil;
        tempField = objc_getAssociatedObject(sender, LARGE_BTN_REF);
        UITextField* tempMField = nil;
        tempMField = objc_getAssociatedObject(sender, CELL_TO_CELL_REF);
        if(tempField)
        {
            tempTxtField = tempField;
            tempMField = nil;
        }
        else
        {
            tempTxtField = tempMField;
            tempField = nil;
        }
        [popTbl setFrame:[(NatolliAppDelegate*)[[UIApplication sharedApplication] delegate] GetTheCordinateFromTextFieldDynamically:tempTxtField WithButton:sender isAssociativeRefAvailable:YES IfAvailableThenIndex:associateIndex]];
        [popTbl isHidden]?[popTbl setHidden:NO]:[popTbl setHidden:YES];
        [popTbl setHidden:NO];

        switch (iPath.row || iPathNew.row)
        {
            case 0:
                tempOfArr = quantArr;
                [popTbl reloadData];
                break;
            case 1:
                tempOfArr = conditionArr;

    }
