VPAccordionAnimation

This is a custom class that provides Accordion Animation for cells expanding and collapsing. i.e., expanding or collapsing of cells with auto adjust to center of view. The expanded cell can contain views data or a complete view controller's data.

IMP

Now VPAccordionAnimation supports Swift 4.0. It now needs XCode 9 or later to build.

Requirements

1. iOS 9.0 or later.
2. ARC memory management.

Usage

Source Code

1. Add the VPAccordionAnimation folder inside your project folder (Contains 4 files. Cell nib file only if customization is not needed. If you have a cell, which is a subclass of VPAccordionAnimationCell, then this file is not needed.)

Using cocoapods

1. Add the pod using pod 'VPAccordionAnimation' in Podfile and use pod install or pod update.
2. Add import VPAccordionAnimation wherever VPAccordionAnimation or it's properties will be used.

Setup procedure

1. Change the parent class of the view controller containing tableView to VPAccordionAnimationViewController. If there is a BaseVC, then change the parent of VPAccordionAnimationViewController to BaseVC
2. Set the isAccordionAnimationEnabled property to true.
3. Call function -

createAccordionDataForIndexPaths(withViewOrControllerData viewData: [AnyObject], forTableView tableView : UITableView)

OR

createAccordionDataForIndexPaths(indexPaths: [NSIndexPath], withViewOrControllerData viewData: [AnyObject], forTableView tableView : UITableView)

for populating the view or viewController data in viewDidLoad().

4. Change the parent class of tableView cell to VPAccordionTableViewCell
5. Add a container view inside the tableView cell and connect the outlet to VPAccordionTableViewCell’s infoView outlet
6. Add all the necessary views that are needed inside the tableViewCells, inside the infoView (as subViews to infoView)
7. Add Constraints to infoView - Leading, Trailing, Top and Height - Do not add bottom constraint
8. If an animation is required for arrow view, then connect it to the arrowView outlet in VPAccordionTableViewCell. Set the arrowImageInitialDirection and arrowImageFinalDirection in subclass
9. You can specify the other optional variables for adding extra functionalities like animation duration, arrowView rotation direction, etc.

VPAccordionAnimationOptions properties

All these options are available inside accordionDataSource property of VPAccordionAnimationController which is a instance of VPAccordionAnimationOptions structure.

You can define the close and open duration speed using the below properties -

var closeAnimationDuration : TimeInterval {get set} var openAnimationDuration : TimeInterval {get set}

You can create the load state for cell on loading using below property - You can either set expanded all or collapsed all. Defaults to collapsed all

var cellDefaultState : DefaultState {get set}

If multiple cell expansion is needed, then set below variable to true

var multipleCellExpansionEnabled : Bool {get set}

When a cell is expanded, if scrolling of tableView has to be enabled, then use the below property.

var tableViewScrollEnabledWhenExpanded : Bool {get set}

You can specify the rotation direction for arrow view (if present, clockwise or anti-clockwise) using the below property

var arrowRotationDirection : ArrowRotation {get set}

AccordionAnimationTableViewCell subclassed properties

If there is an arrow view, you can specify start and end direction of arrow so as to handle the animation by Accordion Animation protocol

var arrowImageInitialDirection : ArrowDirection = .right var arrowImageFinalDirection : ArrowDirection = .down

History

Version 3.0.1

Fixed the Bundle issue due to pods

Version 3.0.0

Now the VPAccordionAnimation supports pods as well. Also it has been migrated to Swift 4 as well.

Version 2.1.1

Fixed the offset issue which causes slight flicking when collapsing the cells

Version 2.1.0

Fixed layout issue when using UITablewViewAutomaticDimension for cells

Version 2.0.0

This version now support Swift 3.0. If you're using XCode lesser than 8, please use the Version 1.3.0 release since this now needs XCode 8 to build and run.

Version 1.3.0

Removed common code facilitating easier integration of AccordionAnimation. Default cells will be added if no customization is needed. Override UITableViewDataSource or UITableViewDelegate methods if needed (like specifying different cell height while expanded, cells content etc.). Default height is entire view height when expanded.

Version 1.2.2

Added support for shadow for bottom screenshot, if needed, and code cleaning.

Version 1.2.1

Code cleaning and added support for disabling cell selection when expanded, if needed.

Version 1.2.0

Added support for expanding or collapsing of view or view controller's view as needed and code cleaning.

Version 1.1.0

Added support for multiple cell expansion and enabled scrolling if variable is set.

Version 1.0.0

Basic Accordion animation classes added and handled arrow view animation.
