这就是我的解。这适用于自定义单元格子类，只需将它们都添加到子类。

- （UIEdgeInset）layoutMargins { 返回 UIEdgeInsetsMake（0， 10， 0， 10）; }

2.

self.separatorInset = UIEdgeInsetsMake(0, 10, 0, 10);

而且很方便，你可以自定义分隔符的位置，而不需要你的设计师为你画一个..........

Swift 2.0扩展

我只是想分享一个扩展，我做了删除边缘从tableview单元格分隔符。

extension UITableViewCell {
    func removeMargins() {

        if self.respondsToSelector("setSeparatorInset:") {
            self.separatorInset = UIEdgeInsetsZero
        }

        if self.respondsToSelector("setPreservesSuperviewLayoutMargins:") {
            self.preservesSuperviewLayoutMargins = false
        }

        if self.respondsToSelector("setLayoutMargins:") {
            self.layoutMargins = UIEdgeInsetsZero
        }
    }
}

用于上下文中:

    let cell = tableView.dequeueReusableCellWithIdentifier("Cell", forIndexPath: indexPath) as! CustomCell

    cell.removeMargins()
    return cell

在Swift中你可以使用这个

    cell.selectionStyle = UITableViewCellSelectionStyle.None
    cell.preservesSuperviewLayoutMargins = false
    cell.separatorInset = UIEdgeInsetsZero
    cell.layoutMargins = UIEdgeInsetsZero

使用下面的代码片段避免不必要的填充问题UITableView在IOS 8和7。

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

    if ([tableView respondsToSelector:@selector(setSeparatorInset:)])
    {
        [tableView setSeparatorInset:UIEdgeInsetsZero];
    }

    if ([tableView respondsToSelector:@selector(setLayoutMargins:)])
    {
        [tableView setLayoutMargins:UIEdgeInsetsZero];
    }

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

只需重写cellForRowAtIndexPath并设置cell。preservessuperviewlayoutmargin = false" and "cell。separatorInset = UIEdgeInsets。零”和“单元格”。layoutmargin = uiedgeinsets . 0 "

override func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {

    let cell: LayoutTableViewCell! = tableView.dequeueReusableCell(withIdentifier: "LayoutCell") as? LayoutTableViewCell



    let currentLayout = OrderLayouts()[indexPath.row]

    cell.NameLabel?.text = currentLayout.name
    cell.DescrLabel?.text = currentLayout.descr

    if(GlobalVariables.debug){

        cell.DescrLabel?.text = "\(currentLayout.id) \n \(currentLayout.descr)"

    }

    cell.preservesSuperviewLayoutMargins = false
    cell.separatorInset = UIEdgeInsets.zero
    cell.layoutMargins = UIEdgeInsets.zero


    return cell

}

添加这个片段，简单优雅的Swift适用于我在iOS8:)

    // tableview single line
func tableView(tableView: UITableView, willDisplayCell cell: UITableViewCell, forRowAtIndexPath indexPath: NSIndexPath) {
    cell.preservesSuperviewLayoutMargins = false
    cell.layoutMargins = UIEdgeInsetsZero
}
