Show stories with specific snap

[vBoykoGit]

I want to start IGStoryPreviewCell from specific start index, myStartIndex for example:

  func collectionView(_ collectionView: UICollectionView, cellForItemAt indexPath: IndexPath) -> UICollectionViewCell {
        guard let cell = collectionView.dequeueReusableCell(withReuseIdentifier: IGStoryPreviewCell.reuseIdentifier, for: indexPath) as? IGStoryPreviewCell else {
            fatalError()
        }
        let story = viewModel?.cellForItemAtIndexPath(indexPath)
        cell.story = story
        cell.delegate = self
       cell.STARTINDEX = myStartIndex // how can i do that?
        nStoryIndex = indexPath.item
        return cell
    }

I have read this issue but still don't understand what property I must set to change start index

Hi @vBoykoGit.

Go to IGStoryPreviewController, willDisplayCell method, you can find the below code,

func collectionView(_ collectionView: UICollectionView, willDisplay cell: UICollectionViewCell, forItemAt indexPath: IndexPath) {
        guard let cell = cell as? IGStoryPreviewCell else {
            return
        }

        //Taking Previous(Visible) cell to store previous story
        let visibleCells = collectionView.visibleCells.sortedArrayByPosition()
        let visibleCell = visibleCells.first as? IGStoryPreviewCell
        if let vCell = visibleCell {
            vCell.story?.isCompletelyVisible = false
            vCell.pauseSnapProgressors(with: (vCell.story?.lastPlayedSnapIndex)!)
            story_copy = vCell.story
        }
        //Prepare the setup for first time story launch
        if story_copy == nil {
            cell.willDisplayCellForZerothIndex(with: cell.story?.lastPlayedSnapIndex ?? 0)
            return
        }
        if indexPath.item == nStoryIndex {
            let s = stories.stories[nStoryIndex+handPickedStoryIndex]
            cell.willDisplayCell(with: s.lastPlayedSnapIndex)
        }
    }

In that, in the below line instead of cell.story?.lastPlayedSnapIndex in cell.willDisplayCellForZerothIndex(with: cell.story?.lastPlayedSnapIndex ?? 0), you can pass your own index like cell.willDisplayCellForZerothIndex(with: 2) or cell.willDisplayCellForZerothIndex(with: 3) like this.

if story_copy == nil {
            cell.willDisplayCellForZerothIndex(with: cell.story?.lastPlayedSnapIndex ?? 0)
            return
        }

Let us know, if you are still unable to fix the issue.

Thanks for your answer. I have changed willDisplay method as following:

if story_copy == nil {
            cell.willDisplayCellForZerothIndex(with: 1)
            return
 }

And now I'm getting this bug:

Hi @vBoykoGit

Can you please tell us, on what scenario you want to open like this?

[vBoykoGit]

I want to open each story separately like following:

So, when I press on the story IGStoryPreviewController should show it.

[boominadhaprakash]

Hi @vBoykoGit

If you are opening each story separately, once that story over, should it move to next story or it should dismiss?

[vBoykoGit]

It should move to the next story
