Didn't tapped on textfield - ios

Question

I create programmatically custom textfield
import UIKit
class SearchTextField: UITextField, UITextFieldDelegate {
let padding = UIEdgeInsets(top: 0, left: 40, bottom: 0, right: 5);
init(frame: CGRect, tintText: String, tintFont: UIFont, tintTextColor: UIColor) {
super.init(frame:frame)
self.frame = frame
delegate = self
backgroundColor = .white
textColor = tintTextColor
placeholder = tintText
font = tintFont
createBorder()
}
required init?(coder aDecoder: NSCoder) {
super.init(coder: aDecoder)
delegate = self
}
func createBorder() {
self.layer.cornerRadius = 6
self.layer.borderColor = UIColor(red: 169/255, green: 169/255, blue: 169/255, alpha: 1).cgColor
self.layer.borderWidth = 1
}
override func textRect(forBounds bounds: CGRect) -> CGRect {
return UIEdgeInsetsInsetRect(bounds, padding)
}
override func placeholderRect(forBounds bounds: CGRect) -> CGRect {
return UIEdgeInsetsInsetRect(bounds, padding)
}
override func editingRect(forBounds bounds: CGRect) -> CGRect {
return UIEdgeInsetsInsetRect(bounds, padding)
}
}
and add it like a subview to my view which is a subview of Google maps view
import UIKit
import GoogleMaps
class MapViewController: UIViewController, UITextFieldDelegate {
#IBOutlet weak var mapView: GMSMapView!
var customSearchBar: SearchTextField!
let searchBarTextColor = UIColor(red: 206, green: 206, blue: 206, alpha: 1)
override func viewDidLoad() {
super.viewDidLoad()
let camera = GMSCameraPosition.camera(withLatitude: 55.75, longitude: 37.62, zoom: 13.0)
mapView.camera = camera
mapView.isUserInteractionEnabled = true
addTopBarView(mapView: mapView)
}
func addTopBarView(mapView: GMSMapView) {
//heigt of topBar is 14% of height of view^ width is the same
let topBarFrame = CGRect(x: 0, y: 0, width: self.view.frame.width, height: self.view.frame.height * 0.14)
let topBarView = UIView(frame: topBarFrame)
addTopBarViewBackground(view: topBarView)
addTitleForTopBarView(view: topBarView)
addProfileIconForTopBarView(view: topBarView)
addSettingsIconForTopBarView(view: topBarView)
addSearchBar(view: topBarView)
topBarView.isUserInteractionEnabled = true
mapView.addSubview(topBarView)
}
func addSearchBar(view: UIView) {
let frameCustomSearchBar = CGRect(x: 10, y: 45, width: view.frame.width - 20, height: 40)
let fontCustomSearchBar = UIFont(name: "HelveticaNeueCyr", size: 28) ?? UIFont.italicSystemFont(ofSize: 14)
let textColorCustomSearchBar = UIColor(red: 206/255, green: 206/255, blue: 206/255, alpha: 1)
customSearchBar = SearchTextField(frame: frameCustomSearchBar, tintText: NSLocalizedString("find_petrole", comment: ""), tintFont: fontCustomSearchBar, tintTextColor: textColorCustomSearchBar)
customSearchBar.delegate = self
customSearchBar.isUserInteractionEnabled = true
customSearchBar.isEnabled = true
let iconPinView = UIImageView(image: #imageLiteral(resourceName: "icon_pin"))
iconPinView.frame = CGRect(x: 10, y: 10, width: 12, height: 20)
customSearchBar.addSubview(iconPinView)
let iconAddView = UIImageView(image: #imageLiteral(resourceName: "icon_add"))
iconAddView.frame = CGRect(x: customSearchBar.frame.width - 34, y: 10, width: 20, height: 20)
customSearchBar.addSubview(iconAddView)
view.addSubview(customSearchBar)
}
The textfield(customSearchBar) i see but it doesn't clickable, when i tapped on it nothing happens. I saw a few such problems here but did not find anything that help me.

Answer 1

You need inspect UIView Hierarchy using View Debugging feature of xcode and you need to check that textfield does not overlap with other view.
Run the app. View Debugging works in the simulator and on devices, but it's important to note that it needs to be an iOS 8 simulator or device. That said, you may allow earlier deployment targets in your project, just make sure you run on iOS 8 when you try View Debugging.
Navigate to the screen/view that you want to inspect within the running app.
In the Navigators Panel (left column), select the Debug Navigator (sixth tab). Next to your process, you'll see two buttons – press the rightmost button and select View UI Hierarchy

Answer 2

I guess it's because you put the UITextField under other touchable views so the touch event was intercepted.
if you make the custom textField hierarchy by a non-defalut isUserInteractionEnabled object, remember to enable it.
