Do i need to copy the Animator folder or did i do something wrong that the code can not recognized the animator? Even though i see in your commit message that you fixed the issue the pod didn't include the animator? Thank @KelvinJin

The firstly, sorry for title :)

Can we make like this?

Where would I alter the code to allow fast scrolling? By fast scrolling, I am referring to the fact that the current animations allow "one cell at a time" scrolling, rather than the typical UIScrollView scrolling.

In particular, what I think would be useful would be to allow for fast scrolling and then upon stopping (either manually, or once the animation finishes), snapping to the closest cell.

I know the author of this is busy, but if someone could point me in the right direction, perhaps I can create a pull request and work on it myself.

I try to swipe continue card layout I found some cell disappear on the left like this https://imgur.com/a/s11ec
*** it not the first cell

how can I fix It

There is a problem scrolling 1-st and 2-nd pages. Pages are blinking during slow scrolling. For pages number higher than 3 it works fine. Reproduced on iPhone 8 plus so far for example app.

I'm using your current projects master branch. When I run the project the Parallax Collection view in portrait it looks great. The issue is when I turn it landscape the cells do not resize property( The experience should be the same as portrait - only one cell showing). Could you please fix this issue on a separate branch? Thank you!

Here is an image illustrating the issue:

Thanks to your nice library.

But cannot use with Cocoapods...

is it a temporary problem or not use with Cocoapods?

Hi,

When I install the library with CocoaPods the Animators folder is missing.

I tried pod deintegrate, pod update and pod install many times but nothing works.

Thanks!

Hi,
I'm working with an autoplay feature and have two questions.

First one is that to go to next indexPath, I'm using the scrollToItem function, but is not always working as expected, sometimes it scrolls and sometimes not.

collectionView.scrollToItem(at: nextIndexPath, at: UICollectionViewScrollPosition.left, animated: true)

Maybe I'm missing something here..

And second, there's a way to change the speed of the animation of scrollToItem? Looks it's fixed by the system..

Thanks!

If I set the width and spacing of the CollectionItem, then how do I calculate the position parameter in the Delegate I need to modify the original code logic if there is a better way to deal with this ?

Is it possible to override this layout, and make the cells wrap? IE: when the collection view gets to the last index, it animates back to the first.

The CubeAttributesAnimator animation does not display correctly in Right-to-Left layouts, e.g. for Arabic language.
When setting the flipsHorizontallyInOppositeLayoutDirection = true, the animation is not displayed correctly.

I tried 0.1.2 on Swift 2.3 and apparently I get errors. Is there a version supported by Swift 2.3?

So as you swipe out the current cell, the next cell zooms into place. Is something like this possible?

Hi.
I trying to add the possibility for scroll left/right by a button tap.
It is possible? Please help someone.

In "#selector" i put code below, but it not work :

mainCollection.scrollToItem(at: IndexPath(item: item, section: 0), at: .centeredHorizontally, animated: true)

Thanks

As the title says. If not, could there be in the future?

Thanks :)

after i followed the thing, i got this as result.

It doesnt seem like it working right. Just a normal CollectionView and even the snap is not on point. Can you help me with this? I am newbie.

the following code

super.viewDidLoad()

        animator = (ParallaxAttributesAnimator(), true)
        // Uncomment the following line to preserve selection between presentations
        // self.clearsSelectionOnViewWillAppear = false

        // Register cell classes
//        self.collectionView!.register(SimpleCollectionViewCell.self, forCellWithReuseIdentifier: "CollectionCell")
//        
//        self.collectionView?.register(<#T##cellClass: AnyClass?##AnyClass?#>, forCellWithReuseIdentifier: <#T##String#>)

        // Do any additional setup after loading the view, typically from a nib.
        
        // Must turn paging on.
        collectionView?.isPagingEnabled = true
        
        if let layout = collectionView?.collectionViewLayout as? AnimatedCollectionViewLayout {
            layout.animator = animator?.0
        }

AnimatedCollectionViewLayout.swift:78:33: 'UICollectionViewScrollDirection' has been renamed to 'UICollectionView.ScrollDirection'

when i scroll i need index path. how can i get that indexpath.??

Hi,
Does the collectionView has to be full screen?
What if I want to pin my collectionView to the 1/3 top ?
Is it possible ?

thanks :)

I can't use any property in objective-c (eg: layout.animator), none of them are visible.

I have installed as mentationed by assigning the animation layout to collection view but not able to see the full width animation.
See the Atachment

Can I use the animations for vertical scroll ( I need "Page" animation ) ??

hey! well this works well while we have UICollectionViewCtr when we try to Customize it to ViewController By just setting flowLayout of CollectionView.

Now i have left and right button and i want the same Procedure of scroll animation on the click of these two button Action.

if any one have performed this then please help.

Firstly thank you for this library, exactly what i need is the library :) I tried all of Attributes Animators, they all working well but CubeAttributesAnimator not working.

This will give you an intuition of the problem. Thank you

Description

Hi,

I use this library and choose CubeAttributesAnimator in my iOS app, but screen display is strange. When I implement photo gallery with full screen, I can only see half photo.
I think it seems to be caused by a bug of internal animation logics.

thanks :)

Environments

AnimatedCollectionViewLayout Version: 1.0.0
Xcode version: 11.1
Swift version: 5.1
Platform(s) running AnimatedCollectionViewLayout: iOS
macOS version running Xcode: 10.15.1

ScreenShots

Strange Finished Pagination:

Expected Collect State Finished Pagination:

When I run the app the collectionView shrinks each cell and displays them all at once on the screen.

I followed readme and added this to my viewDidLoad()

let layout = AnimatedCollectionViewLayout()
layout.animator = ParallaxAttributesAnimator()
collectionView.collectionViewLayout = layout 

is it possible to make card layout size smaller. i mean to display two cell in one screen?if its possible how can i achieve that ?

I'm currently trying to set spacing between my collection view cells. The issue is every time I scroll horizontally the cell does not reset back to where is should be.

Please Look at image bellow!

Here is my code:

extension ImageCollectionViewController: UICollectionViewDelegateFlowLayout {
override func numberOfSections(in collectionView: UICollectionView) -> Int {
    return 1
}

override func collectionView(_ collectionView: UICollectionView, numberOfItemsInSection section: Int) -> Int {
    return Int(Int16.max)
}

override func collectionView(_ collectionView: UICollectionView, cellForItemAt indexPath: IndexPath) -> UICollectionViewCell {
    let c = collectionView.dequeueReusableCell(withReuseIdentifier: cellIdentifier, for: indexPath)

    if let cell = c as? SimpleCollectionViewCell {
        let i = indexPath.row % vcs.count
        let v = vcs[i]
        cell.bind(color: v.0, imageName: v.1)
        cell.clipsToBounds = animator?.1 ?? true
    }

    return c
}

func collectionView(_ collectionView: UICollectionView, layout collectionViewLayout: UICollectionViewLayout, sizeForItemAt indexPath: IndexPath) -> CGSize {
    guard let animator = animator else { return view.bounds.size }
    return CGSize(width: view.bounds.width / CGFloat(animator.2), height: view.bounds.height / CGFloat(animator.3))
}

func collectionView(_ collectionView: UICollectionView, layout collectionViewLayout: UICollectionViewLayout, insetForSectionAt section: Int) -> UIEdgeInsets {
    return .zero
}

func collectionView(_ collectionView: UICollectionView, layout collectionViewLayout: UICollectionViewLayout, minimumLineSpacingForSectionAt section: Int) -> CGFloat {
    return 10
}

func collectionView(_ collectionView: UICollectionView, layout collectionViewLayout: UICollectionViewLayout, minimumInteritemSpacingForSectionAt section: Int) -> CGFloat {
    return 0
}
}

Also here are images showing what happens:

Hello,
How can I make the paging cards vertical instead of moving horizontal when swiping.
This is in the demo.

How to customize item size？（eg: LinearCardAttributesAnimator）

How can this be implemented in a table view instead of container view?
Thanks!

I am wondering why the status bar not visible in the collection view. would you mind helping me make it visible?

I like LinearCardAttributesAnimator() but I need to customize it. Is it possible to make it more linear, without zoom effect and place cells very close to each other?

Right not it seems like the Parallax effects the background of the cell and what's in front. I was wondering if there is a way to change this so the text on the cell is not effected by Parallax? Therefore the "Text/UILabel" does not move with the Parallax as you scroll?

Where is this error coming from? I'm using a UICollectionViewController, and have initialized the AnimatedCollectionViewLayout in viewDidLoad, but it still doesn't work..

Hello! I want to do an animation for one element, for example if the user has one item in the collection, so that he can at least scroll to the left or right (as with default behavior). What is the best way to implement this? Thanks.

Hi,
I use CubeAttributesAnimator and setup in viewDidLoad
layout.animator = CubeAttributesAnimator(perspective: -1 / 800, totalAngle: .pi / 4) layout.scrollDirection = .horizontal layout.invalidateLayout()
but layout broken on CollectionView,
`func collectionView(_ collectionView: UICollectionView, layout collectionViewLayout: UICollectionViewLayout, sizeForItemAt indexPath: IndexPath) -> CGSize {
return CGSize(width: UIScreen.main.bounds.width, height: UIScreen.main.bounds.height)
}

func collectionView(_ collectionView: UICollectionView, layout collectionViewLayout: UICollectionViewLayout, insetForSectionAt section: Int) -> UIEdgeInsets {
    return .zero
}

func collectionView(_ collectionView: UICollectionView, layout collectionViewLayout: UICollectionViewLayout, minimumLineSpacingForSectionAt section: Int) -> CGFloat {
    return 0
}

func collectionView(_ collectionView: UICollectionView, layout collectionViewLayout: UICollectionViewLayout, minimumInteritemSpacingForSectionAt section: Int) -> CGFloat {
    return 0
}`

In addition to CocoaPods it would be great to be able to include this project via Carthage.

I'm seeing that cells are not centered in RotateInOut (and other animators) - meaning at the center position of the scroll - using isPagingEnabled - the cell is rotated.

let layout = AnimatedCollectionViewLayout()
layout.animator = RotateInOutAttributesAnimator(minAlpha: 1)
myChartCollectionView.collectionViewLayout = layout
myChartCollectionView.frame = CGRect(x: 0, y: 144, width: 414, height: 718)
layout.itemSize = CGSize(width: 384, height: 624)
layout.minimumLineSpacing = 0
layout.minimumInteritemSpacing = 0
layout.sectionInset = UIEdgeInsets(top: 0, left: 0, bottom: 0, right: 0)
myChartCollectionView.isPagingEnabled = true
layout.scrollDirection = .horizontal

myChartCollectionView.dataSource = self
myChartCollectionView.delegate = self

Is this a bug in the center/rotation calculator AnimatedCollectionViewLayout or a setting/config I'm missing? TY!

Is it possible to have this kind of collectionView UI with 5 cells with infinite scrolling with this repo?

I use AnimatedCollectionViewLayout a bit differently by storing UITableViews and UITableViewCells in them with the parent UIViewController referenced with a protocol. In other words, it's architected like so:

UITableViewCell --> UITableView --> UICollectionViewCell --> UICollectionView --> UIViewController (using AnimatedCollectionViewLayout)

The parent class using this framework may or may not return a UICollectionViewCell with a UITableView init, and all the UITableViewDataSource and Delegate methods are managed in the parent class (we used our own protocol to do this). BUT, when I updated to version 0.3.0, the frames are frozen when the transition occurs. The animator used is the

ParallaxAttributesAnimator

I think the error occurs because of one of the return values in the animations. Please take a look when you can, and if you need help feel free to reach out!

How to achieve equal spacing between items?

private func configureAttributes(for attributes: UICollectionViewLayoutAttributes) {
    guard let collection = collectionView else { return }
    var visibleRect = CGRect()
    visibleRect.origin = collection.contentOffset
    visibleRect.size = collection.bounds.size
    let collectionLeft =  itemSize.width / 2
    let offset = collection.contentOffset.x
    let normalizedLeft =  attributes.center.x  - offset

    let maxDistance =  self.itemSize.width
    let distance = min(abs(collectionLeft - normalizedLeft), maxDistance)
    let ratio = (maxDistance - distance)/maxDistance
    let scale = ratio * (1 - sideItemScale) + sideItemScale

    var t = CATransform3DIdentity
    t = CATransform3DScale(t,  scale, scale, 1.0)
    attributes.zIndex = Int(scale * 10)
    attributes.transform3D = t

}

is it still not supporting rtl language ?
when making "flipsHorizontallyInOppositeLayoutDirection" true
the animation is very corrupted

Hello! Thanks for this framework! I use the Cube, I have a UIViewController that is completely filled with UICollecitonView, I want to achieve this result when the user swiping away on the last page (to the left) and first page (to the right) then hide the UIViewController with this animation. Tell me how best to do this?
