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并在下次将其设置为true，则无法选择之前选择的行，但不会标记。

如何解决？ isEditing按按钮更改。 enter image description here ''' PermanentInternalViewController类：UIViewController，UITableViewDelegate，UITableViewDataSource，UITextFieldDelegate，UIGestureRecognizerDelegate {

已解决。问题出在cell.selectionStyle = .none 如果将其删除并为表视图使用清晰的背景色，则一切正常。

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