Formed in 2009, the Archive Team (not to be confused with the archive.org Archive-It Team) is a rogue archivist collective dedicated to saving copies of rapidly dying or deleted websites for the sake of history and digital heritage. The group is 100% composed of volunteers and interested parties, and has expanded into a large amount of related projects for saving online and digital history.
DynamicHeightFlowLayout
What does it do ?
This project contains a simple flow layout class that allows you to fill the screen with cells of varying height in multiple columns.
All you have to do is set the class in the flow layout section of the collectionview ,number of columns and the padding in the IBInspector, required section insets and your good to go.
In my project i have set a top/left/bottom/right section inset of 20 and a padding of 20.
Oh ya , one more thing implement the DynamicHeightFlowLayoutDelegate as so
guard let feedLayout = self.collectionView.collectionViewLayout as? DynamicHeightFlowLayout else{
assertionFailure("could not get feed layout")
return
}
feedLayout.delegate = selfand then provide the height for each item in the method
func heightForItem(at indexPath: IndexPath) -> CGFloat {
var height:CGFloat = 0
switch indexPath.item {
case 0 :
height = 170
case 1 :
height = 150
case 2 :
height = 179
case 3 :
height = 350
case 4 :
height = 379
case 5 :
height = 300
case 6 :
height = 192
default :
height = 100
}
return height
}Note :
This repo also contains the drag-drop feature for UICollectionView , have a look at the implementation if needed.
