Display UIButton in UITableView , when Cell is selected

Question

I Want to add a UIButton to my UITableViewCell.My cells expands in height when it is selected.. The button must only be displayed when didSelectRow is called in the expanded area ... I have 4 cells that I want to populate with different questions, forms and buttons. Should I sub-class each cell?

This is my code so far:

let SelectedCellHeight: CGFloat = 500.0
let UnselectedCellHeight: CGFloat = 44.0
func numberOfSectionsInTableView(tableView: UITableView) -> Int {
    return 1
}

func tableView(tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
    return 4
}

func tableView(tableView: UITableView, cellForRowAtIndexPath indexPath: NSIndexPath) -> UITableViewCell {
    let logItemCell = tableView.dequeueReusableCellWithIdentifier("LogCell", forIndexPath: indexPath) as! UITableViewCell




}

// Used to expand cell when selected
func tableView(tableView: UITableView!, heightForRowAtIndexPath indexPath: NSIndexPath!) -> CGFloat {
    if let selectedCellIndexPath = selectedCellIndexPath {
        if selectedCellIndexPath == indexPath {
            return SelectedCellHeight
        }
    }
    return UnselectedCellHeight
}


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

    if let selectedCellIndexPath = selectedCellIndexPath {
        if selectedCellIndexPath == indexPath {
            self.selectedCellIndexPath = nil
        } else {
            self.selectedCellIndexPath = indexPath
        }
    } else {
        selectedCellIndexPath = indexPath
    }
    tableView.beginUpdates()
    tableView.endUpdates()

}

Yes, you should make 4 prototype cells with different identifier and class and return the one you want in 'cellForRowAtIndexPath' depending on the indexPath.

You should subclass each cell that you want. And when didSelectRow is called and the cell is expanded button.hidden = false should be called
