👋 Ritesh -

I'm having trouble setting the insets for my CollectionView programmatically (I'm not using a story board). Right now it's taking up the entire view, but I need it to appear below some text and above a button at the bottom of the view.

For a typical UICollectionView I've used sectionInset to set it in the proper position:

let layout: UICollectionViewFlowLayout = UICollectionViewFlowLayout()
layout.sectionInset = UIEdgeInsets(top: 178, left: 10, bottom: 40, right: 10)
collectionView = UICollectionView(frame: self.view.frame, collectionViewLayout: layout)

This doesn't seem to work for tagCellLayout. Any ideas?

Thanks for the help 😊

I've noticed that when there are wide cells (max possible width) there's a bug with calculating lineNumber.

Let's say my collectionView has 320 px width and I try to put 320 px cell (tag). Problem persists because you call createLayoutAttributes which moves currentTagPosition to (320.0, 0.0) and then call configureWhiteSpace which checks if we should move tag to next row. This method takes currentTagPosition which is 320 px already and adds current tag width again (which is also 320 px).

My suggestion is to create layout attributes for all tags first and then configure white space checking next tag instead of current tag. I've tested it for left alignment and it worked fine.

When i install this wonderful tools with cocoapods, there is an exception saying "TagCellLayout (~> 0.2)required byPodfile". But if i try to use 0.1 version, it could not find the 0.1 branch. "Remote branch 0.1.0 not found in upstream origin" thank you!

Hi, I am trying to fetch the size of collection view height from the override method collectionViewContentSize in TagCellLayout, which is total height of tag cells in the collection view, that might be incorrect in the case of multiple cells in a row. Currently I am using the latest version 1.0.

Prior to the latest version, I was using 0.3, in which the collectionViewContentSize is calculated from the number of lines property and that was returning correct value. Does anyone get similar kind of issue.

Hey @riteshhgupta I just want to make TagCellLayout horizontally and want to reduce vertically space between two items. Please let me know the correct way.

Thanks in advance.

Add a variable called "lineNumber" to record how many lines of tags view. So that users can calculate the contentSize of UICollectionView dynamically and change the constraints of UICollectionView. (In the case of this UICollectionView is embeded in other views or animationing)

Hi @riteshhgupta ,

Related to your last commit , you've updated the ReadMe according to a new 0.2.0 version of TagCellLayout.

When it will be released and available on Cocoapods ?

Thanks

It would be nice to have properties like delegate and tagAlignmentType as IBInspectible. It will be helpful in setting these values by storyboard without having to write a single line of code for initialization.

Pull request contains:

1. Update an example project:

• I made a small correct of example cell so there is no white rectangle out of shape
• I enabled a selection in example as the purpose of tags is to be able to select them

2. I added 2 methods to delegate:

func tagCellLayoutInteritemHorizontalSpacing(layout: TagCellLayout) -> CGFloat func tagCellLayoutInteritemVerticalSpacing(layout: TagCellLayout) -> CGFloat

I'm not sure that values these methods provide are used in correct places of layout calculating but it seems to work.

As using this we set Cell's width through its delegate method.but the cell configuration like corner radius and shadow are done on cell's initialization so how to update UI on getting new sizes from delegate.

Implement a function like from UICollectionViewFlowLayoutDelegate

- (CGFloat)collectionView:(UICollectionView *)collectionView layout:(UICollectionView *)collectionViewLayout minimumInteritemSpacingForSectionAtIndex:(NSInteger)section  
  {
    return 10; // This is the minimum inter item spacing, can be more
  }

Hello,

I have a problem with your class TagCelLayout, in iPhone 5S, the multiline not working.

I see that the collection view width is not representative to the reality with iPhone 5s in the function shouldMoveTagToNextRow. It work perfectly on iPhone 6s.

If you need more informations, please contact me :)
