swift 3 ios tableview 按单元滚动 [英] swift 3 ios tableview scroll by cell

问题描述

我创建了一个 tableview，它按预期正常工作.但是，我想改变滚动方式，用户一次只能滚动一个单元格，这样，单元格永远不会被切成两半.

I created a tableview and it works normally as intended. However, I would like to change the scrolling such a way where the user can only scroll one cell at a time so that, there is never a time where the cell is cut in half..

这是一个例子:http://imgur.com/ffmk0jP

所以基本上我不希望默认滚动..我希望它一次滚动一个单元格以始终保持原始状态的视图..

So basically i do not want the default scrolling.. i would like it to be scrolled one cell at a time to constantly remain with the view of the original state..

有办法吗?
