4.2.0

Dependency changelog -> DTModelStorage 2.1 and higher

This release aims to improve storage updates and UI animation with UICollectionView. To make this happen, DTModelStorage classes were rewritten and rearchitectured, allowing finally to remove truly historic workaround. This code was initially written to fix first item insertion and deletion of items in UICollectionView. Somewhere between iOS 6 and iOS 8 Apple has fixed bugs, that caused this behaviour to happen. This is not documented, and was not mentioned anywhere, and i was very lucky to find this out by accident. So finally, I was able to remove these workarounds (which by the way are almost two years old), and UICollectionView UI updates code is as clean as UITableView UI updates code.

There are some backwards-incompatible changes in this release, however Xcode quick-fix tips should guide you through what needs to be changed.

Added

• registerNiblessCellClass and registerNiblessSupplementaryClass methods to support creating cells and supplementary views from code

Bugfixes

• Fixed cellConfiguration method, that was working incorrectly
• Fixed retain cycles in event blocks

4.1.0

Features

New events registration system with method pointers, that automatically breaks retain cycles.

For example, cell selection:

manager.cellSelection(PostsViewController.selectedCell)

func selectedCell(cell: PostCell, post: Post, indexPath: NSIndexPath) {
    // Do something, push controller probably?
}

Alternatively, you can use dynamicType to register method pointer:

manager.cellSelection(self.dynamicType.selectedCell)

Other available events:

• cellConfiguration
• headerConfiguration
• footerConfiguration
• supplementaryConfiguration

Breaking changes

beforeContentUpdate and afterContentUpdate closures were replaced with DTCollectionViewContentUpdatable protocol, that can be adopted by your DTCollectionViewManageable class, for example:

extension PostsViewController: DTCollectionViewContentUpdatable {
    func afterContentUpdate() {
        // Do something
    }
}
