具体的效果可以参考微信ios7版的UITableview 它最后一行cell的separator是顶到最左边的

首先设置tableFooterView

[objc] view plaincopy

1. _messageTableview.tableFooterView = [[UIView alloc] initWithFrame:CGRectZero];  

然后在willDisplayCell上增加如下代码 控制最后一行separatorInset位置

[objc] view plaincopy

1. - (void)tableView:(UITableView *)tableView willDisplayCell:(UITableViewCell *)cell forRowAtIndexPath:(NSIndexPath *)indexPath{  
2.         NSMutableDictionary *dic = [typeArray objectAtIndex:indexPath.section];  
3.         NSMutableDictionary *infoDic = [dic objectForKey:@"dic"];  
4.         if (indexPath.row==[infoDic count]-1) {  
5.             NSLog(@"indexPath.row===%d",indexPath.row);  
6.             cell.separatorInset = UIEdgeInsetsMake(10, 0, 0, 0);  
7.         }  
8. }
