TGLStackedViewController

A stack layout with gesture-based reordering using UICollectionView -- inspired by Passbook and Reminders apps.

What's new in 2.2

  • Reimplementation of item reordering using UIKit drag and drop on iOS 11.0

What's new in 2.0

  • Uses iOS 9 collection view reordering API instead of own implementation, therefore minimum deployment target is iOS 9.0
  • Unexposed items are pinned to bottom by default, now
  • The exposed item can be collapsed interactively in addition to tapping it
    • When pinning (the default) pan item down to switch back to stacked layout
    • When just pushing cards aside use pinch gesture instead
  • Improved sample project w/ lots of settings to tweak interactively

TGLStackedViewExample

Getting Started

Take a look at sample project TGLStackedViewExample.xcodeproj. You may use sample class TGLViewController as a starting point for your own implementation.

Usage

Via CocoaPods:

  • Add pod 'TGLStackedViewController', '~> 2.2' to your project's Podfile

Via Carthage:

  • Add github "gleue/TGLStackedViewController", ~> 2.2 to your project's Cartfile

Or the "classic" way:

  • Add files in folder TGLStackedViewController to your project

Then in your project:

  • Create a subclass derived from TGLStackedViewController
  • Implement the UICollectionViewDataSource protocol in your subclass
    • Currently only 1 section is supported therefore your implementation of -numberOfSectionsInCollectionView has to return 1. TGLStackedViewController provides a suitable implementation for you -- no need to overwrite.
    • Implement methods -numberOfSectionsInCollectionView: and -collectionView:cellForItemAtIndexPath as usual.
    • New in 2.0: TGLStackedViewController's implementation of method -collectionView:canMoveItemAtIndexPath: checks for stacked layout and a minimum number of 2 items before allowing reordering. Make sure to call super in your implementation and honor it's result.
    • New in 2.0: Implement method -collectionView:moveItemAtIndexPath:toIndexPath: to update your data model after items have been reordered
  • Implement the UICollectionViewDelegate protocol in your subclass
    • TGLStackedViewController already implements methods -collectionView:shouldHighlightItemAtIndexPath:, -collectionView:didDeselectItemAtIndexPath, and -collectionView:didSelectItemAtIndexPath: internally, so make sure to call super in your implementation.
    • Method -collectionView:targetContentOffsetForProposedContentOffset: is crucuial for properly transitioning betwenn exposed and stacked layout, so make sure to call super in your implementation.
  • Place UICollectionViewController in your storyboard and set its class to your derived class
    • Make sure to set up the collection view's delegate and dataSource connections properly
  • New in 2.0: TGLStackedViewController does no longer create a layout object internally.
    • Set the collection view controller's layout class to TGLStackedLayout or your own subclass of TGLStackedLayout in the inspector in Interface Builder.
    • When creating a TGLStackedViewController in code you have to set the collection view's layout before presenting the view controller.

Requirements

  • ARC
  • iOS >= 9.0
  • Xcode 9.0
