UITableView separator lines disappear between cells on scroll

separatoruitableview

Problem: The separator between cells in a table view appear only for those cells shown when the view loads, and only at load time. When the tableview is scrolled down, the cells scrolled into view show no separator between them, then when the tableview is scrolled back up, the initial cells show no separator.

Details: I've got a UITableView to which I'm adding standard UITableViewCells. These cells are created with initWithFrame, frame height = 90px. I'm adding a custom view created from a nib to this cell's view, height = 90px. The cell height is specified at 90px in tableView:heightForRowAtIndexPath:.

Has anyone experienced this behavior?

I had a feeling the solution to this would be simple... I made the height of my cells 91px and the separator lines appear as they should on scroll.

UITableView is a subclass of UIScrollView, so you can also use:

[mainTableView scrollRectToVisible:CGRectMake(0, 0, 1, 1) animated:YES];

[mainTableView setContentOffset:CGPointZero animated:YES];

And in Swift:

mainTableView.setContentOffset(CGPointZero, animated:true)

And in Swift 3 & above:

mainTableView.setContentOffset(.zero, animated: true)

UITableView separator line disappears when selecting cells in iOS7

I haven't gotten to the bottom of it yet (at first glance it seems like an iOS 7 bug..), but I have found a workaround. In tableView:didSelectRowAtIndexPath, if you send both messages below, the issue is visually resolved (with the probable performance cost).

[tableView deselectRowAtIndexPath:indexPath animated:YES];
[tableView reloadRowsAtIndexPaths:@[indexPath] withRowAnimation:UITableViewRowAnimationAutomatic];

For this to work (for me), deselectRowAtIndexPath:animated: must contain animated:YES. The animation used for reloadRowsAtIndexPaths:withRowAnimation: doesn't matter.
