在我的应用中，我使用了splitView。有3个不同的表。
当我从第一张表中选择任何一行时，详细视图中的显示和＆amp;在左侧菜单中保持选中行。但是，当我从第2或第3表中选择任何一行时，该行仅用蓝色和＆amp;快速消失选定的蓝色（即它不会保持突出显示）。
帮我解决这个问题。
我的代码如下：
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
static NSString *CellIdentifier=@"CellIdentifier";
UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier];
cell = [[[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:CellIdentifier] autorelease];
if (cell == nil) {
cell = [[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:CellIdentifier];
}
if(tableView == tbl_class)
{
btnEdit1 = [UIButton buttonWithType:UIButtonTypeCustom];
[btnEdit1 setFrame:CGRectMake(220, 15, 20, 20)];
[btnEdit1 addTarget:self action:@selector(btnEditPressed:) forControlEvents:UIControlEventTouchUpInside];
[btnEdit1 setImage:[UIImage imageNamed:@"edit-3-black.png"] forState:UIControlStateNormal];
UIButton *btnDelete = [UIButton buttonWithType:UIButtonTypeCustom];
[btnDelete setFrame:CGRectMake(260, 15, 20, 20)];
[btnDelete addTarget:self action:@selector(btnDelete:) forControlEvents:UIControlEventTouchUpInside];
[btnDelete setImage:[UIImage imageNamed:@"recycle-bin2.png"] forState:UIControlStateNormal];
[btnEdit1 setTag:indexPath.row];
[btnDelete setTag:indexPath.row];
cell.textLabel.text=[NSString stringWithFormat:@"%@",[[classNames objectAtIndex:indexPath.row]valueForKey:@"class_name"]];
if(! isEditing)
{
[cell.contentView addSubview:btnEdit1];
[cell.contentView addSubview:btnDelete];
}
}
if(tableView==tbl_assessment)
{
if (classNames.count > 0)
{
[btnAddAssesst setHidden:NO];
}
else
{
[btnAddAssesst setHidden:YES];
}
cell.textLabel.text=[NSString stringWithFormat:@"%@",[[assessment_list objectAtIndex:indexPath.row]valueForKey:@"assessment_name"]];
}
if (tableView==tbl3)
{
cell.textLabel.text=[arr_result objectAtIndex:indexPath.row];
}
cell.textLabel.font=[UIFont fontWithName:@"Trebuchet MS" size:17.0f];
cell.textLabel.textColor=[UIColor grayColor];
return cell;
}

答案 0 :(得分：1)
将行保持为选中状态要做两件事
deselectRowAtIndexpath不应该在didselectRowAtIndexpath -cellForRowAtIndexpath方法中检查索引路径是否在单元格中，如果在那里，则生成[tablecell setSelected:YES];否则没有
