各セルに1つのテーブルビューがあり、編集とキャンセルとして2つのボタンがあります。同じセル番号で編集ボタンを同時にクリックすると、キャンセル ボタンの画像が変わるはずです。例えば。ユーザーが 2 番目のセルの編集ボタンを選択すると、2 番目のセルのキャンセル ボタンのみがそのイメージを変更する必要があります。

私の問題は、セルの編集ボタンをクリックすると、別のセルのキャンセルボタンの画像が自動的に変更されることです。

ユーザーが最初のセルをクリックしたときに、他のセルではなく最初のセルのキャンセルボタンのみが変更されるようにしたいですか? どうすればこれを行うことができるかサンプルを教えてください。私が知っているように、セルを再利用するためのこのハプニングcozは？

 - (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
     simpleTableIdentifier = @"MenuNameCell";
     MenuNameCell *cell = (MenuNameCell *)[tableView    dequeueReusableCellWithIdentifier:simpleTableIdentifier];

      if (cell== nil) {
        NSArray *nib = [[NSBundle mainBundle] loadNibNamed:@"MenuNameCell" owner:self options:nil];
        cell = [nib objectAtIndex:0];
        NSLog(@"---------new cell agin");   
    }
       else
    {
        NSArray *arrayView = [cell.contentView subviews];
        for (UIView *vTemp in arrayView)
        {
            [vTemp removeFromSuperview];
        }

        NSLog(@"---No New Cell hiiii");

    }
    // Creating Label Menu Name
    _nameLabel = [[UILabel alloc] initWithFrame:CGRectMake(8, 11, 82, 21)];
    _nameLabel.backgroundColor = [UIColor clearColor];
    _nameLabel.text =  [_hotel._orderedMenus objectAtIndex:indexPath.row];

    // Creating Label Menu Cost
    _amountMenu   = [[UILabel alloc] initWithFrame:CGRectMake(167, 13, 44, 21)];

カスタムセルを使用してから、このコードをカスタムクラスに右挿入し、特定のセルの特定の送信者を取得します

-(IBAction)yourButtonMehod:(id)sender
{
    UIView *senderButton = (UIView*) sender;
    NSIndexPath *indexPath = [(UITableView *)self.superView indexPathForCell: (UITableViewCell*)[[senderButton superView]superView]];
}

これで、送信者を取得でき、 indexpath.row を使用して何でもできます

ボタンアクションメソッドで

-(IBAction)cellButtonPressed:(id)sender withEvent:(UIEvent *)event
{
    UITouch * touch = [[event allTouches] anyObject];
    CGPoint location = [touch locationInView: bulletinTable];
    NSIndexPath * indexPath = [bulletinTable indexPathForRowAtPoint: location];
}

そしてあなたの cellForRowAtIndexPath メソッド

[cell.accessory addTarget:self action:@selector(cellButtonPressed:withEvent:) forControlEvents:UIControlEventTouchUpInside];

これはうまくいくはずです。
