ios – 选中时向表格单元格添加滑动视图

概述我有一个动态表视图,其中包含从db填充的单元格. 选择单元格后,用户应该可以选择其他几个选项. 我知道如何在选择单元格时推送另一个视图但我不喜欢这种方法. 例如,如果相同的单元格可以翻转并显示选项(然后翻转)可能会更轻松,这可能会更好. 或者整个单元格可以从屏幕滑出显示选项,或者另一个视图可以从单元格向下滑动然后向上滑动. 哪种解决方案最容易做到？ 有人能指出我正确的方向吗？我当然不需要代码,我在 我有一个动态表视图,其中包含从db填充的单元格.

或者整个单元格可以从屏幕滑出显示选项,或者另一个视图可以从单元格向下滑动然后向上滑动.

哪种解决方案最容易做到？
有人能指出我正确的方向吗？我当然不需要代码,我在这里学习,我只需要知道要看什么.
到目前为止,我已经阅读了关于UItableVIEwCell的子类化的内容,但老实说,我还没有得到它.
任何输入将不胜感激.

解决方法 您将使用具有前景和背景视图的UItableVIEwCell子类以及UIPanGestureRecognizer.此识别器将触发滑动并处理前景视图的移动.

那说,你会在这里找到一个实现：https://github.com/spilliams/sparrowlike

重要的一点：
