Dynamic UITableView controlled by second UITableView in same ViewController - Swift - ios

Question

This is a followup to a question I asked yesterday, I thought I had a solution based upon the answer received, but I'm having a new difficulty.
I have a single ViewController with two UITableViews (PropertyTypeListand PropertyDetailList)
I essentially want to treat this like a Master Detail View, When a row in PropertyTypeList is selected PropertyDetailList updates to an array based upon that selection. (I need it to be in one ViewController)
The problem was that I couldn't get the row selected from didSelectRowAtIndexPath into cellForRowAtIndexPath where I populate the tables through an If Statement to determine which tableview is in play.
I am now getting the currently selected row through a variable (currentRowInTypeList) and using that value to switch which array is loaded into PropertyDetailList.
Even though currentRowInTypeList is updating with each click the table isn't. What am I missing?
my code follows:
#IBOutlet weak var propertyTypeList: UITableView!
#IBOutlet weak var propertyDetailList: UITableView!
var testarray = ["test1", "test2"]
var testarray2 = ["test3", "test4"]
var currentRowInTypeList: Int = 0
func tableView(tableView: UITableView!, numberOfRowsInSection section: Int) -> Int
{
if tableView == propertyTypeList {
return projectSources.count;
}
else {
if currentRowInTypeList == 0 {
return testarray.count
} else {
return testarray2.count
}
}
}
func tableView(tableView: UITableView!,
cellForRowAtIndexPath indexPath: NSIndexPath!) -> UITableViewCell!
{
let cell:UITableViewCell = UITableViewCell(style:UITableViewCellStyle.Default, reuseIdentifier:"Cell")
if tableView == propertyTypeList {
cell.textLabel?.text = projectSources[indexPath.row]
return cell
}
else
{
if currentRowInTypeList == 0 {
cell.textLabel?.text = testarray[indexPath.row]
return cell
} else {
cell.textLabel?.text = testarray2[indexPath.row]
return cell
}
}
}
func tableView(tableView: UITableView, didSelectRowAtIndexPath indexPath: NSIndexPath) {
tableView.deselectRowAtIndexPath(indexPath, animated: true)
let cell:UITableViewCell = UITableViewCell(style:UITableViewCellStyle.Default, reuseIdentifier:"Cell")
if tableView == propertyTypeList {
currentRowInTypeList = indexPath.row
println(currentRowInTypeList)
} else {
}
}

Just call propertyDetailList.reloadData()
In your code:
func tableView(tableView: UITableView, didSelectRowAtIndexPath indexPath: NSIndexPath) {
tableView.deselectRowAtIndexPath(indexPath, animated: true)
let cell:UITableViewCell = UITableViewCell(style:UITableViewCellStyle.Default, reuseIdentifier:"Cell")
if tableView == propertyTypeList {
currentRowInTypeList = indexPath.row
propertyDetailList.reloadData()
println(currentRowInTypeList)
} else {
}
}
