Change image in UITableViewCell when selected

Question

I want to change the image in a custom UITableViewCell , depending on whether it is selected or not. So, when user selects a row, the image in two rows has to be changed (both the current selected and the one to be selected). Calling reloadData , or reloadRowsAtIndexPaths from didSelectRowAtIndexPath doesn't work because it deselects the current selected row, which I don't want to happen. Calling reloadData from willDeselectRowAtIndexPath and willSelectRowAtIndexPath also causes the same problem. Anyone know a solution for this?

Answer 1

Did you try just programmatically selecting the row in cellForRowAtIndexPath based on a stored property indicating the selected row?

I would an approach where you still use reloadData , or reloadRowsAtIndexPaths from didSelectRowAtIndexPath but first save the selected row in a property so that you can manually set it as selected when the cell is redrawn.

For example:

var selectedRow:NSIndexPath? = nil

override func tableView(tableView: UITableView, didSelectRowAtIndexPath indexPath: NSIndexPath) {
    selectedRow = indexPath
    tableView.reloadData() // or reload a specific row
}

override func tableView(tableView: UITableView, cellForRowAtIndexPath indexPath: NSIndexPath) -> UITableViewCell {
    let cell = tableView.dequeueReusableCellWithIdentifier("TableViewCellReuseIdentifier")
    if (indexPath == selectedRow) {
        cell!.selected = true
    } else {
        cell!.selected = false
    }
}
