About

This project is maintained by Ramotion, Inc.
We specialize in the designing and coding of custom UI for Mobile Apps and Websites.

Try this UI control in action

Requirements

  • iOS 8.0+
  • Xcode 7.3

Installation

Just add the FoldingCell.swift file to your project.

or use CocoaPods with Podfile:

pod 'FoldingCell', '~> 2.0.3' 

or Carthage users can simply add Mantle to their Cartfile:

github "Ramotion/folding-cell"

or just drag and drop FoldingCell.swift file to your project

Solution

Usage

1) Create a new cell inheriting from FoldingCell

2) Add a UIView to your cell in your storyboard or nib file, inheriting from RotatedView. Connect the outlet from this view to the cell property foregroundView. Add constraints from this view to the superview, as in this picture:

1.1

(constants of constraints may be different). Connect the outlet from this top constraint to the cell property foregroundViewTop . (This view will be shown when the cell is in its normal state).

3) Add other UIViews to your cell, connect the outlet from this view to the cell property containerView. Add constraints from this view to the superview like in the picture:

1.2

(constants of constraints may be different). Connect the outlet from this top constraint to the cell property containerViewTop. (This view will be shown when the cell is opened)

Your result should be something like this picture:

1.3

Demonstration adding constraints for foregroundView, containerView

4) Set @IBInspectable var itemCount: NSInteger property is a count of folding (it IBInspectable you can set in storyboard). range 2 or greater. Default value is 2

Ok, we've finished configuring the cell.

5) Adding code to your UITableViewController

5.1) Add constants:

fileprivate struct C {
  struct CellHeight {
    static let close: CGFloat = *** // equal or greater foregroundView height
    static let open: CGFloat = *** // equal or greater containerView height
  }
}

5.2) Add property for calculate cells height

     var cellHeights = (0..<CELLCOUNT).map { _ in C.CellHeight.close }

5.3) Override method:

    override func tableView(tableView: UITableView, heightForRowAtIndexPath indexPath: NSIndexPath) -> CGFloat {
        return cellHeights[indexPath.row]
    }

5.4) Added code to method:

    override func tableView(tableView: UITableView, didSelectRowAtIndexPath indexPath: NSIndexPath) {
        guard case let cell as FoldingCell = tableView.cellForRowAtIndexPath(indexPath) else {
          return
        }

        var duration = 0.0
        if cellHeights[indexPath.row] == kCloseCellHeight { // open cell
            cellHeights[indexPath.row] = kOpenCellHeight
            cell.selectedAnimation(true, animated: true, completion: nil)
            duration = 0.5
        } else {// close cell
            cellHeights[indexPath.row] = kCloseCellHeight
            cell.selectedAnimation(false, animated: true, completion: nil)
            duration = 1.1
        }

        UIView.animateWithDuration(duration, delay: 0, options: .CurveEaseOut, animations: { _ in
            tableView.beginUpdates()
            tableView.endUpdates()
        }, completion: nil)
    }

5.5) Control if the cell is open or closed

  override func tableView(tableView: UITableView, willDisplayCell cell: UITableViewCell, forRowAtIndexPath indexPath: NSIndexPath) {

        if case let cell as FoldingCell = cell {
            if cellHeights![indexPath.row] == C.cellHeights.close {
                foldingCell.selectedAnimation(false, animated: false, completion:nil)
            } else {
                foldingCell.selectedAnimation(true, animated: false, completion: nil)
            }
        }
    }

6) Add this code to your new cell class

    override func animationDuration(itemIndex:NSInteger, type:AnimationType)-> NSTimeInterval {

        // durations count equal it itemCount
        let durations = [0.33, 0.26, 0.26] // timing animation for each view
        return durations[itemIndex]
    }

if don't use storyboard and xib files

Create foregroundView and containerView from code (steps 2 - 3) look example: Folding-cell-programmatically
