推荐答案

全局声明这些变量

BOOL isSelectedAll;
NSMutableArray *arraySelectedRows;
int allDataCount; // this may be your arrayWithData.count

在viewDidLoad"中

in 'viewDidLoad'

isSelectedAll = NO;
allDataCount = 10;
arraySelectedRows = [[NSMutableArray alloc]init];

在'cellForRowAtIndexPath'中

in 'cellForRowAtIndexPath'

- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath {
//    UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:@"ce" forIndexPath:indexPath];
CustomTableViewCell *cell = [[CustomTableViewCell alloc]initWithStyle:UITableViewCellStyleDefault reuseIdentifier:@"cee"];
cell.textLabel.text = @"Test";
UIButton *buttonSelection = [[UIButton alloc]initWithFrame:CGRectMake(tableView.frame.size.width - 100, 8, 50, 50)];
buttonSelection.tag = indexPath.row;
if(isSelectedAll)
{
    [buttonSelection setImage:[UIImage imageNamed:@"tick"] forState:UIControlStateNormal];//Rename imageName as yours
}
else if([arraySelectedRows containsObject:indexPath]&&indexPath.row!=0)
{
    [buttonSelection setImage:[UIImage imageNamed:@"tick"] forState:UIControlStateNormal];//Rename imageName as yours
}
else
{
    [buttonSelection setImage:[UIImage imageNamed:@"untick"] forState:UIControlStateNormal];//Rename imageName as yours
}

[buttonSelection addTarget:self action:@selector(selectionButtonAction:) forControlEvents:UIControlEventTouchUpInside];
[cell addSubview:buttonSelection];
return cell;
}

在didSelectRowAtIndexPath"中

in 'didSelectRowAtIndexPath'

- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:     (NSIndexPath *)indexPath
{
if (indexPath.row == 0)
{
    //select all button
    if (isSelectedAll)
    {
        isSelectedAll = NO;
        [arraySelectedRows removeAllObjects];
    }
    else
    {
        [arraySelectedRows removeAllObjects];
        for (int i = 1; i<allDataCount; i++)
        {
            [arraySelectedRows addObject:[NSIndexPath indexPathForRow:i inSection:0]];//section number may be defer for you
        }
        isSelectedAll = YES;
    }
}
else
{
    if([arraySelectedRows containsObject:indexPath])
    {
        [arraySelectedRows removeObject:indexPath];

    }
    else
    {
        [arraySelectedRows addObject:indexPath];
    }
    if ((allDataCount - 1) == arraySelectedRows.count)
    {
        isSelectedAll = YES;
    }
    else
    {
        isSelectedAll = NO;
    }
}
[self.tableView reloadData];
}

如果你需要在按钮动作中做同样的事情

if you need to do the same thing in button action

-(void)selectionButtonAction:(UIButton*)button
{
if (button.tag == 0)
{
    //select all button
    if (isSelectedAll)
    {
        isSelectedAll = NO;
        [arraySelectedRows removeAllObjects];
    }
    else
    {
        [arraySelectedRows removeAllObjects];
        for (int i = 1; i<allDataCount; i++)
        {
            [arraySelectedRows addObject:[NSIndexPath indexPathForRow:i inSection:0]];//section number may be defer for you
        }
        isSelectedAll = YES;
    }
}
else
{
    NSIndexPath *buttonIndexPath = [NSIndexPath indexPathForRow:button.tag inSection:0];//section number may be defer for you
    if([arraySelectedRows containsObject:buttonIndexPath])
    {
        [arraySelectedRows removeObject:buttonIndexPath];

    }
    else
    {
        [arraySelectedRows addObject:buttonIndexPath];
    }
    if ((allDataCount - 1) == arraySelectedRows.count)
    {
        isSelectedAll = YES;
    }
    else
    {
        isSelectedAll = NO;
    }
}
[self.tableView reloadData];
}

'arraySelectedRows' 包含选定行的 indexPath

The 'arraySelectedRows' contain selected row's indexPath
