1.系统默认的颜色设置

//无色
cell.selectionStyle = UITableViewCellSelectionStyleNone;
//蓝色
cell.selectionStyle = UITableViewCellSelectionStyleBlue;
//灰色
cell.selectionStyle = UITableViewCellSelectionStyleGray;

2.自定义颜色和背景设置
** 改变UITableViewCell选中时背景色：**
UIColor color = [[UIColoralloc]initWithRed:0.0green:0.0blue:0.0alpha:1];//通过RGB来定义自己的颜色*

   cell.selectedBackgroundView = [[[UIView alloc] initWithFrame:cell.frame] autorelease];
   cell.selectedBackgroundView.backgroundColor = [UIColor xxxxxx];

3自定义UITableViewCell选中时背景

    cell.selectedBackgroundView = [[[UIImageView alloc] initWithImage:[UIImage imageNamed:@"cellart.png"]] autorelease]; 
    还有字体颜色 
    cell.textLabel.highlightedTextColor = [UIColor xxxcolor];  
    [cell.textLabel setTextColor:color];//设置cell的字体的颜色

4.设置tableViewCell间的分割线的颜色

  [theTableView setSeparatorColor:[UIColor xxxx ]];

5、设置cell中字体的颜色

// Customize the appearance of table view cells.
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{  
    if( !indexPath.row )  {
        cell.textLabel.textColor = ...; 
        cell.textLabel.highlightedTextColor = ...;
    }
    ...
}
