iOS 11 Inverted Mode Problem

[luzianscherrer]

Description

In iOS 11 (beta 5) in inverted mode the action buttons are displayed upside down.

Reproducible in:

SlackTextViewController version: 1.9.5
iOS version(s): iOS 11 beta 5 / Xcode 9 beta 5
Device(s): any

Steps to reproduce:

1. Create SLKTextViewController in inverted mode (default)
2. Add action buttons to UITableViewCell

I have the same issue

@dzenbot maybe something you could have a look at since you have been so gracious fixing the iOS 11 issue in #624

cheers

It’s in the list of things to fix but I encourage everyone to help out. We’re all devs after all.

My current workaround is using https://github.com/benguild/BGTableViewRowActionWithImage and then adding images instead of text labels like this:

UIImage *buttonImage = [UIImage imageNamed:@"CellButtonTrash"];
if([UIDevice currentDevice].systemVersion.floatValue >= 11) {
    buttonImage = [UIImage imageWithCGImage:buttonImage.CGImage
                                      scale:buttonImage.scale
                                orientation:UIImageOrientationDown];
}

Not that great, but it works.

Are you inverting the entire table view cell btw?

[luzianscherrer]

Yes, I'm doing cell.transform = self.tableView.transform in tableview:cellForRowAtIndexPath:. It's funny that the order of the buttons is not inverted (which means the buttons are not rotate) but just the labels on them.

I'm looking for ways to get the default UISwipeActionView(?) looks like there is is a way in iOS 11 tableView:trailingSwipeActionsConfigurationForRowAtIndexPath. See docs.

We also see the same issue, I'll continue the search for a solution.

Here's workaround , until we find better option
if floatVersion >= 11 { for view in tableView.subviews { if view.isKind(of: NSClassFromString("UISwipeActionPullView")! ) == true { for subview in view.subviews { subview.transform = tableView.transform } break } } }

This code has to be called on this function
func tableView(_ tableView: UITableView, editActionsForRowAt indexPath: IndexPath) -> [UITableViewRowAction]?

[dzenbot]

What doesn't make sense is that the tableView is already inverted with a transform, which means its subviews should inherit the transformation.

[dKasabwala]

not sure why but this code seems to fix it

[dKasabwala]

Actually that subview added when you try to swipe on cell

[dzenbot]

That would explain it. It’s created lazily sincd iOS 11, added to the tableview as subview without inheriting the transformation. Tricky.

[dzenbot]

I wonder if we should just deprecate the inverted mode altogether. It was a hacky approach to start with, plus the non-inverted mode has gotten pretty good since the latest releases.

@dzenbot is it possible to achieve the inverted effect (cells sticking to the bottom) without using inverted mode?
