ios – 如何删除UITableViewCell,使用淡入淡出效果并且没有红色删除按钮？

概述在查看了无数的StackOverflow帖子后,没有什么能真正回答如何在淡入淡出和没有红色删除按钮的情况下删除UITableViewCell时使用滑动到关闭. 我的Tableviewcell看起来像一张卡片,因此删除按钮的红色框架打破了卡片形状的这些细胞的连续性和高度感. 这是我目前用来删除的代码,尽管UITableViewRowAnimation上有.fade,但它不会消失. func tabl 在查看了无数的StackOverflow帖子后,没有什么能真正回答如何在淡入淡出和没有红色删除按钮的情况下删除UItableVIEwCell时使用滑动到关闭.

我的tablevIEwcell看起来像一张卡片,因此删除按钮的红色框架打破了卡片形状的这些细胞的连续性和高度感.@H_419_3@

这是我目前用来删除的代码,尽管UItableVIEwRowAnimation上有.fade,但它不会消失.@H_419_3@

func tableVIEw(_ tableVIEw: UItableVIEw,shouldindentWhileEditingRowAt indexPath: IndexPath) -> Bool {    return false}func tableVIEw(_ tableVIEw: UItableVIEw,editingStyleForRowAt indexPath: IndexPath) -> UItableVIEwCellEditingStyle {    return .none}func tableVIEw(_ tableVIEw: UItableVIEw,commit editingStyle: UItableVIEwCellEditingStyle,forRowAt indexPath: IndexPath) {    if editingStyle == .delete {        self.pastOrders.remove(at: indexPath.row)        tableVIEw.deleteRows(at: [indexPath],with: .fade)    }}

这是我试图实现的行为的屏幕截图：@H_419_3@
