Make custom title view click able swift - ios

Question

I customise the title view add a image and labels in it know I want to make it clickable but its not working. I added tap gesture in title view but its not working.
here is my code.
func navTitleWithImageAndText(titleText: String,subTitleText:String, imageName: String) -> UIView {
// Creates a new UIView
let titleView = UIView()
let label = UILabel(frame: CGRect(x: 0, y: -15, width: 0, height: 0))
// Creates a new text label
// let label = UILabel()
label.text = titleText
label.font = UIFont.boldSystemFont(ofSize: 17)
//label.center = titleView.center
label.textColor = .white
//label.textAlignment = NSTextAlignment.center
label.sizeToFit()
let subtitleLabel = UILabel(frame: CGRect(x: 0, y: 5, width: 0, height: 0))
subtitleLabel.backgroundColor = UIColor.clear
subtitleLabel.textColor = UIColor.white
subtitleLabel.font = UIFont.systemFont(ofSize: 12)
subtitleLabel.text = subTitleText
subtitleLabel.sizeToFit()
// Creates the image view
let image = UIImageView()
image.image = UIImage(named: imageName)
// Maintains the image's aspect ratio:
let imageAspect = image.image!.size.width / image.image!.size.height
// Sets the image frame so that it's immediately before the text:
let imageX = label.frame.origin.x - label.frame.size.height * imageAspect - 20
let imageY = label.frame.origin.y
let imageWidth = label.frame.size.height * imageAspect + 15
let imageHeight = label.frame.size.height + 15
image.frame = CGRect(x: imageX, y: imageY, width: imageWidth, height: imageHeight)
image.contentMode = UIView.ContentMode.scaleAspectFit
// Adds both the label and image view to the titleView
titleView.addSubview(label)
titleView.addSubview(image)
titleView.addSubview(subtitleLabel)
// Sets the titleView frame to fit within the UINavigation Title
titleView.sizeToFit()
return titleView
}
add tap gesture in it. but why its not working.
titleView.addGestureRecognizer(titleGestureRecognizer)

Answer 1

I have implemented a tap gesture on a label in the following way:-
Initialize Variable
var tap_gest = UITapGestureRecognizer()
Add gesture on Label. Add the following code in "viewDidLoad()"
if normal label then use below
self.register_as_company_lbl.isUserInteractionEnabled = true // register_as_company_lbl is my label where tap gesture added
self.tap_gest.addTarget(self, action: #selector(registerAsComapany))
self.register_as_company_lbl.addGestureRecognizer(tap_gest)
if on navigation bar title then use below
self.navigationController?.navigationBar.addGestureRecognizer(tap_gest)
Define Selector method in your ViewController Class as following
#objc func registerAsComapany(){//Add your task what you perform, In my case I have to push to another screen
let vc = UIStoryboard.init(name: "Main", bundle: nil).instantiateViewController(withIdentifier: "CompanyDetailsViewController") as! CompanyDetailsViewController
self.navigationController?.pushViewController(vc , animated: true)
}

titleView.isUserInteractionEnabled = true
