swift 3 ios tableview scroll by cell

问题

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..

This is an example: http://imgur.com/ffmk0jP

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..

Is there a way?

回答1:

how about this ?

1. scrollToNearestSelectedRowAtScrollPosition:animated:?

2. tableview scrollRectToVisible:CGRectMake(0, 0, 1, 1) animated:NO];

回答2:

you can use viewWillTransition function for that to stop that issue..

verride func viewWillTransition(to size: CGSize, with coordinator: UIViewControllerTransitionCoordinator){}
