标题: ios - UItableView 用 UIButton 替换复选标记

我只想使用 UIButton 而不是选中标记我成功添加按钮并使其在选择行时作为复选标记但只有行选择是工作按钮不明智不是我想让它工作按钮以及单元格选择截图:

Best Answer-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

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

在'cellForRowAtIndexPath'中

- (UITableViewCell *)tableViewUITableView *)tableView cellForRowAtIndexPathNSIndexPath *)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

- (void)tableViewUITableView *)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];
}

如果你需要在按钮操作中做同样的事情

-(void)selectionButtonActionUIButton*)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”包含选定行的索引路径
