如图  添加如下代码

sTableView.separatorInset = UIEdgeInsetsZero;

sTableView.layoutMargins = UIEdgeInsetsZero;

cell.layoutMargins = UIEdgeInsetsZero;

第二种方法如下图

-(void)viewDidLayoutSubviews

{

[super viewDidLayoutSubviews];

if ([_moreTableView respondsToSelector:@selector(setSeparatorInset:)]) {

[_moreTableView setSeparatorInset:UIEdgeInsetsMake(0,0,0,0)];

}

if ([_moreTableView respondsToSelector:@selector(setLayoutMargins:)]) {

[_moreTableView 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];

}

}
