cell分割线左对齐，不起作用？用下边的方法

ios7下

//ios8下的新方法

-(void)viewDidLayoutSubviews

{

    if ([_iCoureseTabelViewrespondsToSelector:@selector(setSeparatorInset:)]) {

        [_iCoureseTabelViewsetSeparatorInset:UIEdgeInsetsZero];

        

    }

    if ([_iCoureseTabelViewrespondsToSelector:@selector(setLayoutMargins:)])  {

        [_iCoureseTabelViewsetLayoutMargins:UIEdgeInsetsZero];

    }

}

-(void)tableView:(UITableView *)tableView willDisplayCell:(UITableViewCell *)cell forRowAtIndexPath:(NSIndexPath *)indexPath

{

    

    if ([cellrespondsToSelector:@selector(setLayoutMargins:)]) {

        [cell setLayoutMargins:UIEdgeInsetsZero];

    }

    if ([cellrespondsToSelector:@selector(setSeparatorInset:)]){

        [cell setSeparatorInset:UIEdgeInsetsZero];

    }

}

另外一种方法是

在cell init方法里加 


        if ([self respondsToSelector:@selector(setLayoutMargins:)])
        {
            self.preservesSuperviewLayoutMargins = NO;
            self.layoutMargins = UIEdgeInsetsZero;
        }
        if ([self respondsToSelector:@selector(setSeparatorInset:)])
        {
            self.separatorInset = UIEdgeInsetsZero;
        }
