UIImageview click not working - ios

Question

I am very new to swift. I am implementing the functionality for click event for UIIMageview. My Code is below.
override func viewDidLoad() {
super.viewDidLoad()
initialize()
let logout = UIImage(named: "logout.png")
let location = UIImage(named:"location.png")
let appIcon = UIImage(named: "logo.png")
imgLogout.image = logout
imgLocation.image = location
appicon.image = appIcon
// Do any additional setup after loading the view, typically from a nib.
imgLogout.isUserInteractionEnabled = true
let tapGestureRecognizer = UITapGestureRecognizer(target: self, action: #selector(ProductListController.profileImageHasBeenTapped(gesture:)))
//this is where we add the target, since our method to track the taps is in this class
//we can just type "self", and then put our method name in quotes for the action parameter
//finally, this is where we add the gesture recognizer, so it actually functions correctly
imgLogout.addGestureRecognizer(tapGestureRecognizer)
}
func profileImageHasBeenTapped(gesture: UIGestureRecognizer){
print("Triggered")
}
my click event is not triggered. Any body can help me from this.
Any will be appreciated.
XCode version is 8.3.3
Swift version is 3.1

Answer 1

Why not using a UIButton, that is designed for that kind of usage ?
let logout = UIButton(type: .custom)
logout.setImage(UIImage(named: "logout.png"), forState: .normal)
logout.addTarget(self, action: #selector(self.performLogout), for: .touchUpInside)
#objc
func performLogout() {
// Do something
}

Answer 2

It seems like yourchildview not in the front so try it:
yourparentview.bringSubview(toFront: imgLogout)

Answer 3

imageLogOut frame may be out of super view's bounds, please check it.use
self.profileImageHasBeenTapped(gesture:)
instead of
ProductListController.profileImageHasBeenTapped(gesture:)

Answer 4

set user interaction enabled for the image.
// for creating tap gesture recognizer
#IBOutlet weak var imageView: UIImageView!
override func viewDidLoad() {
super.viewDidLoad()
// create tap gesture recognizer
let tapGesture = UITapGestureRecognizer(target: self, action: "imageTapped:")
// add it to the image view;
imageView.addGestureRecognizer(tapGesture)
// make sure imageView can be interacted with by user
imageView.userInteractionEnabled = true
//if tap is not working bring image to front view
self.view.bringSubview(imageView)
}
func imageTapped(gesture: UIGestureRecognizer) {
// if the tapped view is a UIImageView then set it to imageview
if let imageView = gesture.view as? UIImageView {
println("Image Tapped")
//Here you can initiate your new ViewController
}
}
