Hero: Swift 4 - iOS 11 - Cascade transitions doesn't work

[morgan-legal]

Hi,

I'm using Hero in my application and it was working perfectly until iOS 11, I only have one issue though, I'm applying a cascade modifier on the tableView to display the each cells with a delay. I case see the cascade when I build the app on iOS 9 and 10 but not on iOS 11.

Is that a known issue ? Or many something that i'm missing ?

Thanks !
Morgan

this work for me :

        self.tableView.heroModifiers = [.cascade(delta: 2.0, direction: .bottomToTop, delayMatchedViews: true)]

        var i  = 1.0
        for cell in (self.tableView.visibleCells) {

            cell.heroModifiers = [.duration(0.125 * i),.translate(CGPoint.init(x: 0, y: 120))]
            i += 1
        }

Hi @taiphamtiki,

Thank you for your reply. I'm basically doing the same thing but it does not work. Are you testing on iOS 11 ? Which device ?

Thanks,
Morgan

cascade is working for me only when I leave the view controller. I'm setting the hero modifiers into cellForRowAt method of a collectionview... Any help?

[morgan-legal]

Hmm... I will give it a shot with a collectionView. Have you tried using a tableView ? I'm still trying to figure out why this was working on iOS 10 and not iOS 11 anymore...

[morgan-legal]

I can confirm that the cascading effect does not work on a UITableView but it does on a UICollectionView.
The only way to have that effect on tableView cells would be to apply a modifier on each one of them with a delayed ( delta * index ) translate.

I don´t understand why this is closed. I can reproduce the error with iOS 11 and a UITableView.
Or in other words: What is needed to reopen this :-)

@lkzhao can this issue be re-opened ?

[lkzhao]

Yea, definitely. I will take a look this week.

[morgan-legal]

Any updates on this issue @lkzhao ?

i know this is not an answer but try version 0.3.6
I had weird rendering problems in v1.0.0 (and up) when i was linking cell view's with VC's view's so ive decided to stick with 0.3.6

PS. 0.3.6 works fine with Xcode9.4 and iOS11

[morgan-legal]

Yes the issue comes from the 1.0.0 release. I'd rather not roll back to previous versions but find a fix for current one :)

[KonsoltCorp]

Has a fix for this been made yet?

[morgan-legal]

Not that I'm aware of...

I'm unable to use cascate too, but i think that is because the tableView cell are not loaded on the moment that the transition animation occurs, and maybe that moment have changed on iOS 11+

There is not a single cell rendered in viewDidLoad, even you scroll to the position. Try accessing visibleCellson viewDidLayoutSubviews.

Strangely enough, I have set them in almost everywhere in the view lifecycle, but I can only get the cascade animation to work when leaving the view. It seems like the animations are running in viewWillDisappear, but I can't get them to run after populating the datasource and reloading the collectionview. I even tried this hard coding in cells so the view wasn't waiting for a network call to finish. :(
