让cell分割线(separatorLine)补全方法。

###Swift:

1 实现代码:

override func viewDidLayoutSubviews() {
        if tableView!.respondsToSelector("setSeparatorInset:") {
            tableView!.separatorInset = UIEdgeInsetsZero
        }
//
        if tableView!.respondsToSelector("setLayoutMargins:") {
            tableView!.layoutMargins = UIEdgeInsetsZero
        }
    }

2 实现代理方法:

func tableView(tableView: UITableView, willDisplayCell cell: UITableViewCell, forRowAtIndexPath indexPath: NSIndexPath) {
        if cell.respondsToSelector("setSeparatorInset:") {
            cell.separatorInset = UIEdgeInsetsZero
        }
        
        if cell.respondsToSelector("setLayoutMargins:") {
            cell.layoutMargins = UIEdgeInsetsZero
        }
    }

###Objective-C:

1 实现代码:

- (void)viewDidLayoutSubviews {
    
    if ([_tableView respondsToSelector:@selector(setSeparatorInset:)]) {
        _tableView.separatorInset = UIEdgeInsetsZero;
    }
    
    if ([_tableView respondsToSelector:@selector(setLayoutMargins:)]) {
        _tableView.layoutMargins = UIEdgeInsetsZero;
    }
}

2 实现代理方法:

- (void)tableView:(UITableView *)tableView
                                willDisplayCell:(UITableViewCell *)cell
                                forRowAtIndexPath:(NSIndexPath *)indexPath {
    
    if ([cell respondsToSelector:@selector(setSeparatorInset:)]) {
        cell.separatorInset = UIEdgeInsetsZero;
    }

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