How to disable all cells except the selected one

How can I disable interaction with all cells except the selected one, and then enable the interaction after cell is selected again?

I tried like this inside didSelectRowAtIndexPath method:

if cell.isExpanded
    {
        UIView.animateWithDuration(0.3) {
            cell.contentView.layoutIfNeeded()
            self.tableView.userInteractionEnabled = false
            cell.userInteractionEnabled = true
        }
    }

But this will disable the entire tableView including the currently selected cell.

As of first your tableView need to select cell, after that one of the cell is selected you want other cell not to select except that selected cell, for that you can create one instance property of type NSIndexPath and use this to store inside didSelectRowAtIndexPath, and compare its value inside cellForRowAtIndexPath like this way.

var selectedIndexPath: NSIndexPath?

cellForRowAtIndexPath

func tableView(tableView: UITableView, cellForRowAtIndexPath indexPath: NSIndexPath) -> UITableViewCell {
    let cell = tableView.dequeueReusableCellWithIdentifier("cell") as! CustomCell
    if (self.selectedIndexpath != nil) {
        if self.selectedIndexpath == indexPath {
            cell.userInteractionEnabled = true
        }
        else {
            cell.userInteractionEnabled = false
        }
    }
    else {
        cell.userInteractionEnabled = true
    }
    return cell
}

didSelectRowAtIndexPath

func tableView(tableView: UITableView, didSelectRowAtIndexPath indexPath: NSIndexPath) {
    if self.selectedIndexpath != indexPath {
        self.selectedIndexpath = indexPath
    }
    else {
        self.selectedIndexpath = nil
    }
    tableView.reloadData()
}

Note: I have set the cell userInteractionEnabled to true again if you select your expanded cell.

Use 

func tableView(tableView: UITableView, didSelectRowAtIndexPath indexPath: NSIndexPath)

to findout the selected cell and store the indexPath selected in a variable and reload the tableview.

func tableView(tableView: UITableView, cellForRowAtIndexPath indexPath: NSIndexPath) -> UITableViewCell

disable all the cells except the one selected by checking the stored indexPath.

Hope this helps .
