sizeForItem delegate function is not called when peek behavior is configured about mspeekcollectionviewdelegateimplementation HOT 6 CLOSED

Hello @johnCbogil ! Thanks for contributing to this repository by opening this issue!
After the last major update, this library started using a custom layout to position its cells. Since the sizeForItem function is only defined for the UICollectionViewDelegateFlowLayout protocol, technically it doesn't exist from this library's perspective.
The reason why this is done this way is because it's not feasible to let the developer change the size of each item manually. The idea of it is for the developer to specify the peeking and it will automatically calculate the cell sizes and display them.
The init for the behavior has a bunch of attributes you can set to make the library do what you want it to do:

init(cellSpacing: CGFloat = 20, cellPeekWidth: CGFloat = 20, minimumItemsToScroll: Int? = nil, maximumItemsToScroll: Int? = nil, numberOfItemsToShow: Int = 1, scrollDirection: UICollectionView.ScrollDirection = .horizontal, velocityThreshold: CGFloat = 0.2)

You can check the comments in the MSCollectionViewPeekingBehavior class to have more insights on each variable.
If this is not enough for you to be able to move forward happy to discuss with you here what you need to achieve and if it makes sense to add it to the library I'll work on it

Have a great day!

Ok that makes sense, I appreciate your speedy and thorough response @MaherKSantina!

If I understand you correctly, I should attempt to get my desired itemSize via the behavior's initializer? I only need 1 item size so I think this could work.

Thank you!

As far as I remember you can't get the item size from the library, it calculates it internally and updates the cells to be of that size, so you don't have to worry about you setting it. But do you want the item size to drive something outside the collection view? I'm still a bit confused on why you need the item size 😕

Sorry for the confusion. I understand now that I can't use the itemSize delegate function with the library. That makes sense.

My goal is for my items to be square (equal height and width). I believe that I can configure this via the behavior's initialization parameters.

I have solved my issue by doing a bit of math to determine the necessary cellSpacing to create square items.

Thank you @MaherKSantin !

Hahah I was just writing a comment about how to calculate it using spacing and peeking width 😆 I'm glad you were able to solve it on your own! Thank you so much for contributing and feel free to close this issue if your issue is resolved 👍

Have a wonderful day!
