ios - 单击按钮时在 tableViewCell 中配置数据

Question

我正在使用 coreData 属性配置 UITableViewCell。我能够显示文本。但我想在单击按钮时使用其他数据重新加载单元格。

-(void)configureCell:(UITableViewCell *)cell atIndexPath:(NSIndexPath *)indexPath
{
  Book *entity = [self.fetchedResultsController objectAtIndexPath:indexPath];
  firstLabel = [[UILabel alloc]initWithFrame:CGRectMake(0, 10, 120, 21)];
  secondLabel = [[UILabel alloc]initWithFrame:CGRectMake(120, 10, 120, 21)];

  firstLabel.text = entity.title;
  secondLabel.text = entity.author;

  [cell.contentView addSubview:firstLabel];
  [cell.contentView addSubview:secondLabel];

  //On button Click i want to change firstLabel.text = entity.date and secondlabel.text =   entity.details

}

试试这个代码..

设置全局变量

int buttonCliked;

设置按钮的操作

- (IBAction)aaaa:(id)sender
{
    buttonCliked =1;
    [_myTable reloadData];
}

用数据加载tableviewCell

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

UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier];
if (cell == nil) {
    cell = [[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:CellIdentifier];

Book *entity = [self.fetchedResultsController objectAtIndexPath:indexPath];

firstLabel = [[UILabel alloc]initWithFrame:CGRectMake(0, 10, 120, 21)];
secondLabel = [[UILabel alloc]initWithFrame:CGRectMake(120, 10, 120, 21)];

if(!buttonClicked)
{
    firstLabel.text = entity.title;
    secondLabel.text = entity.author;
}
else
{
    firstLabel.text =  entity.date;
    secondLabel.text = entity.details;

    if(indexPath.row >= [tableView numberOfRowsInSection:indexPath.section] && indexPath.section >= [tableView numberOfSections])
    {
        buttonCliked =0;
    }

}

[cell.contentView addSubview:firstLabel];
[cell.contentView addSubview:secondLabel];

return cell;


}
