If I select a expanded cell, it's perfectly alright. But when I go for another selection, both selected cells are being highlighted. So more than one item selection makes this issue. Please let me know if it already has a solution or any way around?

Hi. I get a crash when trying to open expandable cells in different sections. Index out of range. Works fine when opening multiple expandable cells in the same section just not in two (or more I'm assuming) different sections. I need this to work without closing the already opened cell. Not sure how to fix this.

Simplest ViewController code below:

import UIKit
import ExpandableCell



class MyTableViewController: UIViewController {

    
    @IBOutlet var tableView: ExpandableTableView!
    
    
    var cell: UITableViewCell {
        return tableView.dequeueReusableCell(withIdentifier: ExpandedButtonCell.ID)!
    }
    
    override func viewDidLoad() {
        super.viewDidLoad()
        // Do any additional setup after loading the view, typically from a nib.
        tableView.expandableDelegate = self
        //tableView.openAll()
        tableView.register(UINib(nibName: "NormalExpandableCell", bundle: nil), forCellReuseIdentifier: NormalExpandableCell.ID)
        tableView.register(UINib(nibName: "ExpandedButtonCell", bundle: nil), forCellReuseIdentifier: ExpandedButtonCell.ID)
    }
}


extension MyTableViewController: ExpandableDelegate {
    
    
    // Number of sections
    func numberOfSections(in expandableTableView: ExpandableTableView) -> Int {
        return 2
    }
    
    // Number of rows in section
    func expandableTableView(_ expandableTableView: ExpandableTableView, numberOfRowsInSection section: Int) -> Int {
        return 2
    }
    
    // Cells for row at (returns the main top level cells)
    func expandableTableView(_ expandableTableView: ExpandableTableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
        guard let cell = expandableTableView.dequeueReusableCell(withIdentifier: NormalExpandableCell.ID) else { return UITableViewCell() }
        return cell
    }
    
    // Expanded Cells for row
    func expandableTableView(_ expandableTableView: ExpandableTableView, expandedCellsForRowAt indexPath: IndexPath) -> [UITableViewCell]? {
        return [cell, cell, cell]
    }
    
    // height for row
    func expandableTableView(_ expandableTableView: ExpandableTableView, heightForRowAt indexPath: IndexPath) -> CGFloat {
        return 100
    }
    
    
    // heights for expanded row at
    func expandableTableView(_ expandableTableView: ExpandableTableView, heightsForExpandedRowAt indexPath: IndexPath) -> [CGFloat]? {
        return [44, 44, 44]
    }

}


// EXPANDABLE CELLS HERE
class NormalExpandableCell: ExpandableCell {
    static let ID = "NormalExpandableCell"
}


class ExpandedButtonCell: UITableViewCell {
    static let ID = "ExpandedButtonCell"

}

I have a tabbar controller. ViewController A with expandable table view inside View Controller B without. Just empty one

I open A. opened B then Open A

expandable table view is not working and crashes

I reproduced this issue with demo app. Just embed in tabbarcontroller instead of navigation controller. please help

Some time it crashes because filteredExpandedDatas having no object at that time.

func indexPathsWhere(indexPath: IndexPath) -> [IndexPath] { let filteredExpandedDatas = expandableDatas.filter({ (expandedData: ExpandableData) -> Bool in return (expandedData.indexPath == indexPath) }) if filteredExpandedDatas.count > 1 { fatalError("Something Wrong") } return filteredExpandedDatas[0].expandedIndexPaths }

• Adds new ExpansionStyle: singlePerSection;
• Adapts existing code to handle new style.

Notes:

1. This PR is based on PR #53 (where the initial idea for this new case came from);
2. Demo (ExpandableCellDemo) wasn't updated with a new button to test this new expansion style behaviour to avoid "overcrowding" the navigation bar with buttons. TL;DR: it can be easily tested by simply replacing the style (ExpansionStyle.single) currently set in method ViewController.expandSingleButtonClicked(_:) with ExpansionStyle.singlePerSection.

When i click expandable cell and scroll table view or expandable and collap cell, Cell become white . my iphone (ios6s version: 11.4.1) bugCell.zip

I wanted to dynamically update an expanded section, but the current implementation looks really odd to users. I think it is because it is actually removing all visible rows, updating, and then adding rows and updating again.

I just extracted out some of the open/close methods that I would like to use into their own functions, and then call those. I'm open to different names for the extracted functions if you don't like them.

Is there a way that i could should only one expended cell in table. Ex: Let say User selected Cell A it's expended but when User select Cell B, cell A should close and B open automatically.

Hi @younatics ,

This library is cool, I want to use it in one of my applications. But I have issue in rendering the tableviewcell. I manage to use a custom tableviewcell but the problem is the constraints I set in the cell is I think overwritten.

Please see screenshot below.

Storyboard cell with costraints.

Actual result.

Hoping for your response.

Thank you.

Hi @younatics thanks for the neat refactored code!

can you add in the previously requested collapse All and open single expandable cell please?

Cheers

Started getting this error after pod install:

Multiple commands produce '/Users/fedor/Library/Developer/Xcode/DerivedData/...-bgbdsrxqedljvpcbxvkmpclubaes/Build/Products/Debug-iphoneos/.../Assets.car':

1. Target '...' (project '...') has compile command with input '/Users/fedor/.../.../.../Assets.xcassets'
2. That command depends on command in Target '...' (project '...'): script phase “[CP] Copy Pods Resources”

There are also two warnings:

1. duplicate output file '/Users/fedor/Library/Developer/Xcode/DerivedData/...-bgbdsrxqedljvpcbxvkmpclubaes/Build/Products/Debug-iphoneos/.../Assets.car' on task: PhaseScriptExecution [CP] Copy Pods Resources /Users/fedor/Library/Developer/Xcode/DerivedData/...-bgbdsrxqedljvpcbxvkmpclubaes/Build/Intermediates.noindex/.../Debug-iphoneos/.../Script-626E2A68364D360141E2BEDF.sh

2. The app icon set name "AppIcon" is used by multiple app icon sets.

The second one is related to the GoogleMaps pod.

Pod version: 1.3.0. Swift version: 5.1. Xcode version: 11.3.1.

When I call reloadData in the expanded cell, the order of row is scrambled and not sorted in order.

It only happens when compiled in Xcode 13 and run in iOS15. When it's compiled in Xcode 13 and run in iOS14, it has no problem. Also, when it's compiled in Xcode 12, it runs fine in iOS15 and 14.

Could you please fix this? Thank you.

Is there a way to get the Indexpath of parent list. Lets

Parent { index 0 : [child1, child2, child3] index 1 : [child 1, child 2] index 2 : null }

How I can get the indexpath of normal cell when some of cells are expanded. In this case if index 0 is expanded and i click on normal cell then i will get indexpath (0+3+2) = 5. where as i want 2. Any way to achieve this.

If someone can help me to solve this crash issue. Thank you

tableView have more data and expand very first cell and scroll to bottom section and click on the section, app will crash. I found the issue, cImageView gets nil if cell is not visible.

Please fix this.

Thank you for this awesome library,

I've added ExpandableCell in jonkykong/SideMenu pod, but when I try to push a new ViewController and back to the (Side Menu) I can't click on any cell in the TableView at all, all cells freeze. I tried to reloadData and reloadSection but when I back to the menu the cells disappear. I also tried it in the demo, and there is the same issue.

How to solve this issue?
