Swift UIButton background image not being set by UIImagePicker - swift

Question

I am able to select an Image from the PhotoLibrary but the background image of my UIButton does not change. The println in didFinishPickingImage and imagePickerControllerDidCancel does not show in the console so I do not think those functions are being called.
class AddTeamTableViewController: UITableViewController, UITextFieldDelegate, UINavigationControllerDelegate, UIImagePickerControllerDelegate, UIAlertViewDelegate {
var picker:UIImagePickerController? = UIImagePickerController()
#IBOutlet var teamNumber: UITextField!
#IBOutlet var schoolName: UITextField!

#IBAction func cancelButton(sender: AnyObject) {
dismissViewControllerAnimated(true, completion: nil)
}
#IBAction func addTeam(sender: AnyObject) {
var newTeam = Team()
var onlineTeam = PFObject(className: "Team")
// add new team to the list
newTeam.name = teamNumber.text
newTeam.schoolName = schoolName.text
teamList.append(newTeam)
// add online
onlineTeam["name"] = newTeam.name
onlineTeam["fromUser"] = PFUser.currentUser()
onlineTeam["schoolName"] = newTeam.schoolName
onlineTeam.save()
//close the view
dismissViewControllerAnimated(true, completion: nil)
}
override func viewDidLoad() {
super.viewDidLoad()
// Uncomment the following line to preserve selection between presentations

Answer 1

The button doesn't seem initialized
let teamImage: UIButton = UIButton(frame: CGRect(x: 0, y: 0, width: 380, height: 300))
let imageTest = UIImage(named: "Hypnotoad")
teamImage.setTitle("HypnotoadTitle", forState: .Normal)
teamImage.setBackgroundImage(imageTest, forState: .Normal)
tested this in a Playground and works ok.

Answer 2

I figured it out. I had 2 different variables of type UIImagePickerController and I was saving to the wrong one. I deleted the first var picker declaration and combined the code to just one UIImagePickerController and it works as intended.
