我正在制作像whatsApp这样的应用程序请检查whatsApp调用选项卡。当我们点击时，点击编辑当tableview处于编辑模式时我应该如何向左移动单元格。请忽略Ancher函数，我创建了一个单独的函数来处理锚定。 ScreenShot 1 ScreenShot 2

答案 0 :(得分：0)
您的图片看起来好像已将子视图添加到单元格view属性而不是contentView属性。要在编辑期间重新调整内容的大小，您必须将新的UIView添加到contentView属性。
示例：
func setupViews() {
self.contentView.addSubview(frameview)
self.contentView.addSubview(Calltype)
self.contentView.addSubview(Name)
self.contentView.addSubview(Description)
self.contentView.addSubview(infoBtn)
self.contentView.addSubview(TimeLabel)
}
