Swift Use of Unresolved Identifier 'IndexPath' TableView Cell Button - ios

Question

I am attempting to get the text of my UILabel and set it to my Parse object, but I am running into an issue setting the object to the index path of the cell. I am getting an Use of unresolved identifier 'indexPath' error at that line.
follow["following"] = self.userArray.objectAtIndex(IndexPath.row)
Here is my tableview controller:
import UIKit
class SearchUsersRegistrationTableViewController: UITableViewController {
var userArray : NSMutableArray = []
override func viewDidLoad() {
super.viewDidLoad()
var user = PFUser.currentUser()
loadParseData()
}
override func didReceiveMemoryWarning() {
super.didReceiveMemoryWarning()
// Dispose of any resources that can be recreated.
}
// MARK: - Table view data source
override func numberOfSectionsInTableView(tableView: UITableView) -> Int {
return 1
}
override func tableView(tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
return userArray.count
}
override func tableView(tableView: UITableView, cellForRowAtIndexPath indexPath: NSIndexPath) -> UITableViewCell {
let cell: SearchUsersRegistrationTableViewCell = tableView.dequeueReusableCellWithIdentifier("Cell", forIndexPath: indexPath) as! SearchUsersRegistrationTableViewCell
let row = indexPath.row
var individualUser = userArray[row] as! PFUser
var username = individualUser.username as String
var profileImage = individualUser["profileImage"] as? PFFile
if profileImage != nil {
profileImage!.getDataInBackgroundWithBlock({
(result, error) in
cell.userImage.image = UIImage(data: result)
})
} else {
cell.userImage.image = UIImage(named: "profileImagePlaceHolder")
}
cell.usernameLabel.text = username
cell.addUserButton.tag = row
cell.addUserButton.addTarget(self, action: "addUser:", forControlEvents: .TouchUpInside)
return cell
}
func loadParseData() {
var query : PFQuery = PFUser.query()
query.findObjectsInBackgroundWithBlock {
(objects:[AnyObject]!, error:NSError!) -> Void in
if error == nil {
if let objects = objects {
println("\(objects.count) users are listed")
for object in objects {
self.userArray.addObject(object)
}
self.tableView.reloadData()
}
} else {
println("There is an error")
}
}
}
#IBAction func addUser(sender: UIButton) {
println("Button Triggered")
let addUserButton : UIButton = sender
let user : PFObject = self.userArray.objectAtIndex(addUserButton.tag) as! PFObject
var follow = PFObject(className: "Follow")
follow["following"] = self.userArray.objectAtIndex(IndexPath.row)
follow["follower"] = PFUser.currentUser().username
follow.saveInBackground()
}
}
Here is my tableview cell:
import UIKit
class SearchUsersRegistrationTableViewCell: UITableViewCell {
#IBOutlet weak var userImage: UIImageView!
#IBOutlet weak var usernameLabel: UILabel!
#IBOutlet weak var addUserButton: UIButton!
override func awakeFromNib() {
super.awakeFromNib()
userImage.layer.borderWidth = 1
userImage.layer.masksToBounds = false
userImage.layer.borderColor = UIColor.whiteColor().CGColor
userImage.layer.cornerRadius = userImage.frame.width/2
userImage.clipsToBounds = true
}
override func setSelected(selected: Bool, animated: Bool) {
super.setSelected(selected, animated: animated)
// Configure the view for the selected state
}
}

Answer 1

Try this
follow["following"] = self.userArray.objectAtIndex(sender.tag)
You are setting the row as tag for your button. Just use it.

Answer 2

you should not work with tags in that case.
to get the indexpath in your addUser function add the following:
let indexPath = tableView.indexPathForRowAtPoint(addUserButton.convertPoint(CGPointZero, toView: tableView))
then you can use that line:
follow["following"] = self.userArray.objectAtIndex(indexPath.row)
indexPath, not IndexPath
