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;</span>

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];

// Customize the appearance of table view cells.
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
  if(0 == indexPath.row)
  {
    cell.textLabel.textColor = ...;
    cell.textLabel.highlightedTextColor = ...;
  }
  ...
}

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 ]];

// Customize the appearance of table view cells.
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
  if(0 == indexPath.row)
  {
    cell.textLabel.textColor = ...;
    cell.textLabel.highlightedTextColor = ...;
  }
  ...
}
