1、swift实现分割线补全
swift一个大进步，只要设置tableView.separatorInset = UIEdgeInsets.zero即可补全分割线，
2、OC实现分割线补全
而在OC中，我们要实现UITableViewDelegate的两个代理方法才能得到想要的效果。OC实现代码如下
- (void)viewDidLayoutSubviews
{
if ([self.tableView respondsToSelector:@selector(setSeparatorInset:)]) {
[self.tableView setSeparatorInset:UIEdgeInsetsMake(0,0,0,0)];
}
if ([self.tableView respondsToSelector:@selector(setLayoutMargins:)]) {
[self.tableView setLayoutMargins:UIEdgeInsetsMake(0,0,0,0)];
}
}
- (void)tableView:(UITableView *)tableView willDisplayCell:(UITableViewCell *)cell
forRowAtIndexPath:(NSIndexPath *)indexPath
{
if ([cell respondsToSelector:@selector(setSeparatorInset:)]) {
[cell setSeparatorInset:UIEdgeInsetsZero];
}
if ([cell respondsToSelector:@selector(setLayoutMargins:)]) {
[cell setLayoutMargins:UIEdgeInsetsZero];
}
}
