accessing dictionary data from Parse and displaying on Tableview Cell

Question

I have an object with dictionary properties I'm trying to access and display on a tableview cell. I haven't dealt with dictionary type data before, so displaying it has kind of confused me..

this is the object. Its from the class PoolAccount and the data i want to access is in the column "serviceHistory"

var poolHistory:PFObject = PFObject(className: "PoolAccount")
 Print(poolHistory.valueForKey("serviceHistory")!.count!)
 //returns this data

  //How do i cast this data so i can use it in a tableview cell?
  override func tableView(tableView: UITableView, cellForRowAtIndexPath indexPath: NSIndexPath) -> UITableViewCell {
    let cell = tableView.dequeueReusableCellWithIdentifier("cell", forIndexPath: indexPath) as! UITableViewCell


  cell.textLabel?.text = ??

i updated it with a couple pictures @Lamar, its an array of dictionary values. — Steve DeRienzo

you have to use the query those objects from the background using findObjectsInBackgroundWithBlock save it into a dictionary then you could populate it into a cell — Lamour

I think you should change "serviceHistory" column type to Object. You can use NSDictionary

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

var data = poolHistory["serviceHistory"] as! NSArray

var element = data[indexPath.row] as! NSDictionary
var phValue = element["PH"] as! Int

cell.textLabel?.text = "\(phValue)"

}

I need to save multiple objects to this column, does this column as an object only hold one object or can it consist of an array of objects?

sorry i couldn't understand your case. i edited code probably this should work. in your case you use an array ob objects.

unfortunately i can only add one object to the column and not multiple objects unless the column is of type array...having a column of object doesn't allow that..
