Question

我是iphone开发新手。我有一个tableview控制器我想在其他视图中显示所选（多个）单元格（选中标记）值作为标签，我怎么能实现这个？这是我用来检查标记的代码tableview单元格

- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath
{

UITableViewCell *thisCell = [tableView cellForRowAtIndexPath:indexPath];
if (thisCell.accessoryType == UITableViewCellAccessoryNone) {
    thisCell.accessoryType = UITableViewCellAccessoryCheckmark;

}else
{
    thisCell.accessoryType = UITableViewCellAccessoryNone;
}
}
- (UITableViewCellAccessoryType)tableView:(UITableView *)tableView accessoryTypeForRowWithIndexPath:(NSIndexPath *)indexPath {
return UITableViewCellAccessoryNone;
}

Answer 1

在数组中添加Checkmarked Cell的索引，并在Label

中显示该索引处的值

- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath
{
    UITableViewCell *thisCell = [tableView cellForRowAtIndexPath:indexPath];
    if (thisCell.accessoryType == UITableViewCellAccessoryNone) {
        thisCell.accessoryType = UITableViewCellAccessoryCheckmark;
        [myIndexArray addObject:[NSString stringWithFormat:@"%d",indexPath.row]];
    }
    else
    {
        thisCell.accessoryType = UITableViewCellAccessoryNone;
        for(int i=0; i<myIndexArray.count; i++)
        {
            if([[myIndexArray objectAtIndex:i]intValue]== indexPath.row)
            {
                [myIndexArray removeObjectAtIndex:i];
                 break;
            }
        }
    }
}
