Hi and thank you for the great job on that library,

I'm having an issue with what should be a default behavior of the index:

When I tap an item, tableViewIndex(tableViewIndex, didSelectItem, atIndex) is called, but not if I swipe through the index bar. It seems like touchesBegan is called, but not touchesMoved.

Most of my code is copied from the demo example which works perfectly fine, so I don't really know where to investigate.

Do you by any chance have an idea of what causes the issue?

Let me know if you need more info

Thanks!

Everything works fine if I call the following code for the first time:

self.tableView.reloadData()
self.tableIndexController.tableViewIndex.reloadData()

but after I update data source of the table view, that code makes the app freeze because layoutSubviews() gets called infinitely in TableViewIndex. But I need to update the index view, what should I do?

I'm seeing an issue where the labels sometimes disappear, have you seen that before?

It occurs for me in a few different scenarios, like when I bring up the keyboard on iPad in portrait (which doesn't cause the truncation to occur because they all fit on screen) then rotate to landscape (where not all fit on screen so it has to truncate). A lot of the labels disappear, but their frame is preserved so there's space for each but they're not all visible. When I then dismiss the keyboard it expands out to show all but a few labels are not visible. What's interesting is the View Debugger shows the missing labels don't exist as subviews, they're not there at all.

I've been trying to debug it but haven't been able to figure out why this is occurring. It seems to be an issue when the height changes, it calls layoutSubviews in the index view a few times with different heights, but the last one is always correct, yet it ends up not properly creating all the subviews it seems. Or maybe a race condition removing and re-adding? I'm not sure. Hoping you might know where the problem may lie.

This is a bit of a nit pick but in my case it had serious implications. In order to tap outside of the section index to hit a table view row, you have to tap pretty far to the left. You can compare this to the native Contacts app to see the difference. For example, it interferes with the X in the screen shotted view. I tried to handle this through the indexInset property but that did not work.

Hi,

Thanks for the nice library!

I would like to report one small issue that I found while integrating the lib into an Objective-C project. The problem is that indexInset, indexOffset and itemSpacing var-s are missing in auto-generated header and can not be accessed from Objective C. At the same time, when you edit library code and try to specify a different name for any of those properties via @objc(...), compiler starts showing "Property cannot be marked @objc because its type cannot be represented in Objective-C" error.

I made a small investigation and found that indexInset and indexOffset were visible correctly until 510e329ac18bba7c4900150aa2988f94ff1e3721. So, the problem appeared as soon as those struct-s became implicitly unwrapped optionals. If I now simply change them back in a way that they wouldn't be optionals anymore, the problem disappears. If on your opinion this is ok (maybe there is a better solution...), I'll do a merge request.

Here is a new one coming with iOS 13 - when a UITableView is being presented as a modal, the index can't be dragged because it causes rubber banding as that modal's dismissal takes priority.

Just starting to digging into this, but it looks like there's going to need to be some sort of callback to hook into to disable that gesture recognizer during MYTVI touches (see: https://stackoverflow.com/questions/56718552/disable-gesture-to-pull-down-form-page-sheet-modal-presentation).

The TableViewIndex is always displayed on the Right side of the tableView. Since I have Arabic text inside table view which has text from right to left it is so I need the TableViewIndex on the left side

On manual installation, XCode throws error: "Redeclaration of BackgroundView class" As it is declared in Examples.swift and also a separate file named BackgroundView.swift having BackgroundView

I am using this library and it's working great. But it's yet not build with Swift 4.3 as it's required for Xcode 10 now. Please add support for Swift 4.3 so that we can continue using it.

This PR adds configurable minWidth instead of hardcoded 44 points, and extends the TableViewIndexController constructor with styling options so that you don't have to do styling like this: tableViewIndexController.tableViewIndex.font = UIFont.boldSystemFont(ofSize: 12.0)

Hi, Sir! Thanks for such an awesome library.

The issue is basically described in title, so it looks like 0.2.0 version podspec is not pushed to CocoaPods master repo :)

Hi there, I have implement your library in a project and i need click even of tableview cell where listed country name. Can you please help from where i can find that.

It would be nice to have the built in feature described in the title. This is how I did it in the meantime, and here was the result. Result - TableViewIndex pinned to 3rd section

 func scrollViewDidScroll(_ scrollView: UIScrollView) {
        let contentOffsetY = scrollView.contentOffset.y
        if scrollView == tableView && searchBar.text == "" {
            if let visibleRows = tableView.indexPathsForVisibleRows {
                let visibleSections = visibleRows.map({$0.section})
                if let allStopsIndex = sections.index(where: {$0.type == SectionType.AllStops}), let firstAllStopCellIndexPath = visibleRows.filter({$0.section == allStopsIndex && $0.row == 1}).first {
                    let secondCell = tableView.cellForRow(at: firstAllStopCellIndexPath)
                    let newYPosition = view.convert(tableViewIndexController.tableViewIndex.indexRect(), from: tableView).minY
                    if ((newYPosition * -1.0) < (secondCell?.frame.minY)! - view.bounds.midY) {
                        let offset = (secondCell?.frame.minY)! - initialTableViewIndexMidY - contentOffsetY
                        tableViewIndexController.tableViewIndex.indexOffset = .init(horizontal: 0.0, vertical: offset)
                        tableViewIndexController.setHidden(!visibleSections.contains(allStopsIndex), animated: true)
                    }
                }
            }
        }
    }
