Question

我已经制作了一个表格和内容的一些值，我有一个像

这样的按钮

cell.textLabel.textColor = [UIColor whiteColor];

UIButton *btn=[UIButton  buttonWithType:UIButtonTypeCustom];
[btn setBackgroundColor:[UIColor clearColor]];
[btn setBackgroundImage:[UIImage imageNamed:@"edit_button.png"] forState:UIControlStateNormal];
[btn setFrame:CGRectMake(290, 15, 15, 15)];
[btn addTarget:self action:@selector(editTable:) 
       forControlEvents:UIControlEventTouchUpInside];
[cell.contentView addSubview:btn];

NSString *cellValue = [myArrayNew objectAtIndex:indexPath.row];
cell.textLabel.text = cellValue;

return cell;

我想点击该按钮并从该特定索引中获取值

像

阿里（这里按钮）--------索引0 Sajid（这里按钮）--------索引1 罗伯特（按钮在这里）--------索引2 RaM（此处按钮）--------索引3

Theser是表格的单元格，现在如何点击该按钮获取索引？

如果你没有得到我的问题，你可以再问我一次......

Answer 1

我找到了答案，

只需在按钮目标方法中编写以下编码，然后使用clickButtonPath作为索引路径。它工作得很好，只是

UITableViewCell *clickedCell = (UITableViewCell *)[[sender superview] superview];
NSIndexPath *clickedButtonPath = [self.tableView indexPathForCell:clickedCell];

Answer 2

btn.tag = indexPath.row;

然后在(void)editTable:(id)sender：

int row = (UIButton *)btn.tag;

Answer 3

你会用这样的东西。

- (IBAction)editTable:(UIButton *)sender {
   UIView *contentView = [sender superView];
   UITableViewCell *cell = [contentView superView];
   NSIndexPath *indexPath = [self.tableView indexPathForCell:cell];
}

但首先你应该确保正确地重复使用你的细胞。通过这样更改您的代码：

cell = ... dequeue cell ...
if (cell == nil) {
    cell = ... create new cell ...
    UIButton *btn=[UIButton  buttonWithType:UIButtonTypeCustom];
    btn.tag = 194;
    [btn setBackgroundColor:[UIColor clearColor]];
    [btn setBackgroundImage:[UIImage imageNamed:@"edit_button.png"] forState:UIControlStateNormal];
    [btn setFrame:CGRectMake(290, 15, 15, 15)];
    [btn addTarget:self action:@selector(editTable:) 
       forControlEvents:UIControlEventTouchUpInside];
    [cell.contentView addSubview:btn];
}
// if you need to change something for this button you can get it like this:
//UIButton *btn= [cell.contentView viewWithTag:194];
NSString *cellValue = [myArrayNew objectAtIndex:indexPath.row];
cell.textLabel.text = cellValue;

return cell;

如何通过单击按钮（以方法为目标）获取特定行的索引？
