Issue with textview in swift 3 - swift

Question

I am working in a form in swift 3, my problem is when I tried to hide the keyboard in textview because the keyboard reuse to hide and is still visible in the previous VC.
My question is what I missing to fix this and when tap outside of textview the keyboard hide automatically?
Here the code:
override func touchesBegan(_ touches: Set<UITouch>, with event: UIEvent?) {
self.view.endEditing(true)
}
func textFieldShouldReturn(_ textField: UITextField) -> Bool {
textField.resignFirstResponder()
return(true)
}
func textFieldDidBeginEditing(_ textField: UITextField) {
if(textField == names){
scrooView.setContentOffset(CGPoint(x:0, y:250), animated: true)
}
else if(textField == email){
scrooView.setContentOffset(CGPoint(x:0, y:250), animated: true)
}
else if (textField == tel){
scrooView.setContentOffset(CGPoint(x:0, y:250), animated: true)
}
else if (textField == message){
scrooView.setContentOffset(CGPoint(x:0, y:450), animated: true)
}
}
func textFieldDidEndEditing(_ textField: UITextField, reason:
UITextFieldDidEndEditingReason) {
scrooView.setContentOffset(CGPoint(x:0, y:0), animated: true)
}
extension UIViewController{
func hideKeyboard(){
let tap: UITapGestureRecognizer = UITapGestureRecognizer(
target: self,
action: #selector(UIViewController.dismissKeyboard))
view.addGestureRecognizer(tap)
}
#objc func dismissKeyboard(){
view.endEditing(true)
}
}
Here a link with the issue!

Answer 1

You are using a scrollView, try to add the GestureRecognizer in them, like this:
class ViewController: UIViewController {
#IBOutlet weak var scrooView: UIScrollView!
#IBOutlet weak var tfTest: UITextField!
override func viewDidLoad() {
super.viewDidLoad()
scrooView.addGestureRecognizer(UITapGestureRecognizer(target: self, action: #selector(dismissKeyboard)))
// Do any additional setup after loading the view, typically from a nib.
}
override func didReceiveMemoryWarning() {
super.didReceiveMemoryWarning()
// Dispose of any resources that can be recreated.
}
#objc func dismissKeyboard(){
tfTest.endEditing(true)
}
})
If you add your Gesture in your View, it could never actived 'cause you are touching the scrollview that is over the view.
