Should be something like:

A mosaic collection view layout inspired by Lightbox's Algorithm, written in Swift 🔶

layout loses bounds and thumbnails overlay each other after upgrading to iOS 14

Hi there,

I am sorry, to maybe ask a stupid question.

I've installed all proberly. The demo is running nicely with the Asset book images. (y)

Now my problem:

I installed TRMosaikLayout by cocoapods. I am using XCode8 beta6.
I copied the TRCollectionViewController code into an empty UICollectionViewController class.
I added a UICollectionViewController onto my storyboard
I changed the reuseIdentifier to the proberly name
Added the Assets you provide in your example
I changed the cell color to any color (for testing)
Run the project, but cellForItemAt indexPathwas never called.

After a few hours of doom, I commented out the

   ` // self.collectionView!.collectionViewLayout = mosaicLayout`

Now it shows me the cells regularly. But not as Mosaiks. When I comment in this line, the mosaiklayout stays empty.

The cellForItemAt indexPath function don't get called.

What I am missing, what should I do?

Many thanks in advance

Hi, I have a bug when I configure a grid with only small items. Somehow the end of the collectionview is not calculated correctly.

This is the grid scrolled down:

But there are 3 items incorrectly still below the fold. I can see them when I pull the CollectionView up:

My grid has 15 cells and it behaves like this with every number that can be divided by 3. When I add 1 big cell it works. The ViewController is a loaded from a Storyboard.

Any ideas what is wrong?

Hello, found that problem, what is this? my mistake? Scrolling just stop, if there big one cell without 2 small, but i can see it while bouncing collectionview
I like your job, and want to implement in my project, but does it work only with even counts of items?

Hi,

Your library is great! Just found out that collection view isn't scrolling to the last item if the item count is not divisible by 3..it happens in your example code too..
Could you please fix it?

Thanks

Hey, I'd love to see this lib available in Swift 3 so I can implement it in my project.

Thanks 😄

Does this support horizontal scrolling? I tried to set this in the CollectionView in Storyboard but no luck. Thanks.

Anyone else have trouble adding collectionview headers with the Mosaic Layout?

I was watching the latest WWDC and they had a section called "A Tour of UICollectionView". In this section, the instructor creates a mosaic layout like yours by creating a subclass of UICollectionViewLayout just like TRMosaicLayout. Yet the instructor optimizes the layout for scrolling within the layoutAttributesForElements by changing the method from a linear search to a binary. Binary searches are somewhat new to me, so after rewatching the video and doing some research, I found the collection needs to be sorted to be able to run a binary search. My problem is I get a bit confused on how to create the binary search and if your cachedCellLayoutAttributes are sorted already. In the video the instructor says the cachedCallLayoutAttributes are sorted by there frames minimum y value, yet when i debug cachedCellLayoutAttributes it seems that the there frames minimum y value isn't sorted. If you have any ideas or if its even worth doing in the first place let me know. I'll add video link and specific time of video below.

Specific time about optimization within layoutAttributesForElements: 25:40 -> 28:00

I try to make a layout like snapchat gif that you attached with code but there is no any way to set layout pattern like this.

Can you please help me to do i am working with swift 2.2

It seems the right inset is not as large as what it should be.
I set the same value as the left and right insets. But the right displayed inset is smaller than the left.

I am adding images but I can not scroll till the bottom cell,

it says delegeate not found on my class.
i am using objective-c.

Layout works fine when it is initialised in viewDidLoad() but after pull to refresh collectionview lags and becomes very slow on scrolling.

• Does not taking Header/Footer into account
• Does not take into account if we end on a Big cell

The following delegate should be weak: open var delegate: TRMosaicLayoutDelegate!
Being a strong reference lead to a retain cycle on any controller using this delegate.

I will propose a PR soon to fix this if you don't mind.
