FoldingCell
The iPhone mockup available here.
Requirements
- iOS 8.0+
- Xcode 7.3
Installation
Just add the FoldingCell.swift file to your project.
or use CocoaPods with Podfile:
ruby
pod 'FoldingCell', '~> 0.8.1'
or Carthage users can simply add Mantle to their Cartfile
:
github "Ramotion/folding-cell"
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:
(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:
(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:
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:
swift
let kCloseCellHeight: CGFloat = *** // equal or greater foregroundView height
let kOpenCellHeight: CGFloat = *** // equal or greater containerView height
5.2) Add property
var cellHeights = [CGFloat]()
create in viewDidLoad:
override func viewDidLoad() {
super.viewDidLoad()
for _ in 0...kRowsCount {
cellHeights.append(kCloseCellHeight)
}
}
5.3) Override method:
swift
override func tableView(tableView: UITableView, heightForRowAtIndexPath indexPath: NSIndexPath) -> CGFloat {
return cellHeights[indexPath.row]
}
5.4) Added code to method: “` swift override func tableView(tableView: UITableView, didSelectRowAtIndexPath indexPath: NSIndexPath) { let cell = tableView.cellForRowAtIndexPath(indexPath) as! FoldingCell
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: { () -> Void in
tableView.beginUpdates()
tableView.endUpdates()
}, completion: nil)
}
5.5) Control if the cell is open or closed
``` swift
override func tableView(tableView: UITableView, willDisplayCell cell: UITableViewCell, forRowAtIndexPath indexPath: NSIndexPath) {
if cell is FoldingCell {
let foldingCell = cell as! FoldingCell
if cellHeights![indexPath.row] == kCloseCellHeight {
foldingCell.selectedAnimation(false, animated: false, completion:nil)
} else {
foldingCell.selectedAnimation(true, animated: false, completion: nil)
}
}
}
6) Add this code to your new cell class ”` swift 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:
