我有一个应用程序,其中UITableView的分隔符插入设置为自定义值-右0,左0。这在iOS 7中非常有效。x,但是在iOS 8.0中,我看到右边的分隔符被设置为默认值15。即使在xib文件中它设置为0,它仍然不正确地显示。

如何删除UITableViewCell分隔符边距?

在3楼看到答案后,我试图弄清楚设置TableView和TableViewCell之间的分隔符是什么关系,并做了一些测试。以下是我的结论:

we can consider that setting the cell's separator to zero has to move the separator in two steps: first step is to set cell's separatorinset to zero. second step is to set cell's marginlayout to zero. set the TableView's separatorinset and marginlayout can affect the Cell's separatorinset. However, from the test, I find that the TableView's separatorinset seem to be useless, TableView's marginlayout can actually affect cell's marginlayout. set Cell's PreservesSuperviewLayoutMargins = false, can cut off TableView's marginlayout effect on Cells. one of the solutions: func tableView(tableView: UITableView, cellForRowAtIndexPath indexPath: NSIndexPath) -> UITableViewCell { var cell = UITableViewCell() cell.preservesSuperviewLayoutMargins = false cell.separatorInset = UIEdgeInsetsZero cell.layoutMargins = UIEdgeInsetsZero return cell }

XCode 7.1 iOS 7,8,9:

把这两行放到你的TabelViewCell中:

    self.layoutMargins = UIEdgeInsetsZero;
    self.preservesSuperviewLayoutMargins = false;

这对我很有用

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
}

使用storyboard更改分隔符插入自定义左0和右0, 如果你想隐藏分隔符为None 见上图

Lukasz用Swift回答:

    // iOS 7:
    UITableView.appearance().separatorStyle = .SingleLine
    UITableView.appearance().separatorInset = UIEdgeInsetsZero
    UITableViewCell.appearance().separatorInset = UIEdgeInsetsZero

    // iOS 8:
    if UITableView.instancesRespondToSelector("setLayoutMargins:") {
        UITableView.appearance().layoutMargins = UIEdgeInsetsZero
        UITableViewCell.appearance().layoutMargins = UIEdgeInsetsZero
        UITableViewCell.appearance().preservesSuperviewLayoutMargins = false
    }

而不是每次单元格滚动时更新preservessuperviewlayoutmargin和layoutmargin(使用willDisplayCell),我建议在cellForRowAtIndexPath::

override func tableView(tableView: UITableView, cellForRowAtIndexPath indexPath: NSIndexPath) -> UITableViewCell {

    let cell = super.tableView(tableView, cellForRowAtIndexPath: indexPath)

    cell.preservesSuperviewLayoutMargins = false
    cell.layoutMargins = UIEdgeInsetsZero

    return cell

}
