Question

我在每个单元格中有一个表格视图和两个按钮，名为广告编辑和取消。当用户同时点击编辑时，同一行取消按钮图像应该改变。代码工作正常，但当我点击第一个单元格编辑按钮第三个单元格图像的取消按钮正在更改insted od第一个单元格。我该怎么办？这样它就会改变同一个细胞中心按钮的图像..

这是我的代码!!

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

simpleTableIdentifier = @"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");
    // Setting Tag To UIButton
    _checkButton = (UIButton *)[cell.contentView viewWithTag:indexPath.row];
    _cancelButton = (UIButton *)[cell.contentView viewWithTag:indexPath.row];

}
// 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)];
_amountMenu.backgroundColor = [UIColor clearColor];
_amountMenu.text  = [[_hotel._menuPrices objectAtIndex:indexPath.row] stringValue];

// Creating Text Field For Order Quantity
_textFieldQuantity = [[UITextField alloc] initWithFrame:CGRectMake(125,14,42,21)];
_textFieldQuantity.userInteractionEnabled = NO;
_textFieldQuantity.text = [[_hotel._selectedQuantity objectAtIndex:indexPath.row] stringValue];

// Creating Button For Check Order
_checkButton  = [UIButton buttonWithType:UIButtonTypeCustom];
[_checkButton setFrame:CGRectMake(232, 13, 25, 28)];
[_checkButton setTag:indexPath.row];
_checkButton.titleLabel.tag = indexPath.row;
[_checkButton setBackgroundImage:[UIImage imageNamed:@"edit.png"]forState:UIControlStateNormal];
[_checkButton addTarget:self action:@selector(editQuantity:) forControlEvents:UIControlEventTouchUpInside];


// Creating Button For CANCEL Order
_cancelButton  = [UIButton buttonWithType:UIButtonTypeCustom];
[_cancelButton setFrame:CGRectMake(265, 13, 25, 28)];
[_cancelButton setBackgroundImage:[UIImage imageNamed:@"cancel.png"] forState:UIControlStateNormal];
[_cancelButton setTag:indexPath.row];
_cancelButton.titleLabel.tag = indexPath.row;
[_cancelButton addTarget:self  action:@selector(cancelOreder:) forControlEvents:UIControlEventTouchUpInside];


// Adding All To Content View
[cell.contentView addSubview:_nameLabel];
[cell.contentView addSubview:_amountMenu];
[cell.contentView addSubview:_textFieldQuantity];
[cell.contentView addSubview:_checkButton];
[cell.contentView addSubview:_cancelButton];


//objc_setAssociatedObject(_checkButton, iindex, indexPath,OBJC_ASSOCIATION_RETAIN );

return cell;

}

-(void)editQuantity:(id)sender{
button = (UIButton *)sender;
row = button.tag;
col = button.titleLabel.tag;
NSLog(@"Check Button index is %d",row);
NSLog(@"cehck title is %d",col);
_textFieldQuantity.userInteractionEnabled = YES;
 _textFieldQuantity.text = [[_hotel._selectedQuantity objectAtIndex:row] stringValue];

UIImage *buttonImage = [UIImage imageNamed:@"edit_over.png"];
[_checkButton setBackgroundImage:buttonImage forState:UIControlStateNormal];
UIImage *buttonImageCancel = [UIImage imageNamed:@"check.png"];
[_cancelButton setBackgroundImage:buttonImageCancel forState:UIControlStateNormal];
_cancelButton.tag =  0;

} - （无效）cancelOreder：（ID）发送方{

button = (UIButton *)sender;
row = button.tag;
NSLog(@"The Row Selected iS At Cancel Order ISSSS----%d", row);
if (_cancelButton.tag ==  0){
    _textFieldQuantity.userInteractionEnabled = NO;
    UIImage *buttonImageCancel = [UIImage imageNamed:@"check_over.png"];
    [_cancelButton setBackgroundImage:buttonImageCancel  forState:UIControlStateNormal];
    UIImage *buttonImageCancel1 = [UIImage imageNamed:@"cancel.png"];
    [_cancelButton setBackgroundImage:buttonImageCancel1 forState:UIControlStateNormal];
    UIImage *buttonImage = [UIImage imageNamed:@"edit.png"];
    [_checkButton setBackgroundImage:buttonImage forState:UIControlStateNormal];
    _cancelButton.tag = 1;
}
else
{
    UIAlertView *alert =  [[UIAlertView alloc] initWithTitle:@"iHomeDelivery" message:@"Do You Want To Cancel the Order" delegate:self cancelButtonTitle:@"Ok" otherButtonTitles:nil];
    [alert show];
    [alert release];
}

}

在editQuantity中，看起来您正在更改_checkButton和_cancelButton的背景图像，但您没有通过其标记指定特定实例。

您提到第三行的取消按钮正在更改。这是添加到表中的最后一行吗？

EDITED 在editQuantity方法中尝试这样的东西;

UIView *buttonToEdit;
buttonToEdit = [_cancelButton viewWithTag:row];
[buttonToEdit setBackgroundImage:buttonImageCancel forState:UIControlStateNormal];

我还没有测试过，但在这种情况下，buttonToEdit应指向您单击的行中的按钮。因此，您将在同一行的按钮上设置背景图像。

希望它适合你。
