iOS-UITableView 设置分割线长度和颜色

在ios7以前的代码

// 设置距离左右各10的距离

• (void)tableView:(UITableView *)tableView willDisplayCell:(UITableViewCell *)cell forRowAtIndexPath:(NSIndexPath *)indexPath{
  if ([cell respondsToSelector:@selector(setSeparatorInset:)]) {
  [self.myTable setSeparatorInset:UIEdgeInsetsMake(0, 10, 0, 10)];
  }

  if ([cell respondsToSelector:@selector(setLayoutMargins:)]) {
  [cell setLayoutMargins:UIEdgeInsetsZero];
  }
  }

• (void)viewDidLayoutSubviews{
  [super viewDidLayoutSubviews];

  if ([self.myTable respondsToSelector:@selector(setSeparatorInset:)]) {
  [self.myTable setSeparatorInset:UIEdgeInsetsMake(0, 10, 0, 10)];
  }

  if ([self.myTable respondsToSelector:@selector(setLayoutMargins:)]) {
  [self.myTable setLayoutMargins:UIEdgeInsetsZero];
  }
  }

在ios7以后的代码
tableView.separatorInset=UIEdgeInsetsMake(0,10, 0, 10); //top left bottom right 左右边距相同
tableView.separatorStyle=UITableViewCellSeparatorStyleSingleLine

设置分隔线的颜色
self.tableView.separatorColor = rgb();
