Swift isEditing 模式下的 Tableview 不会取消选择单元格

Question

我尝试在 isEditing 模式下使用标准选择。 当我第一次按下时它被选中，但是当我第二次按下时它在视觉上保持选中状态。 如果我将 isEditing 更改为 false 并且下次将其设置为 true 我不能 select 之前选择但它们没有标记的行。

如何解决？ isEditing 通过按钮更改。 在此处输入图像描述''' class PermanentInternalViewController：UIViewController，UITableViewDelegate，UITableViewDataSource，UITextFieldDelegate，UIGestureRecognizerDelegate {

var index = 0
var test = ["dghffhfh",
            "sadasdsa",

解决了。 问题出在 cell.selectionStyle =.none 如果删除它并为 tableview 使用清晰的背景颜色，一切正常。
