Unable to click on Textfield on GMaps for iOS Subview - ios

Question

I would like to add a searchbar (like in the Google Maps App for iOS).
So to look like the same as in that App, ill created a UITextField.
For example:
override func viewDidLoad() {
/* Add Google Map */
let camera = GMSCameraPosition.cameraWithLatitude(49.077872,longitude: 19.450339, zoom: 17)
mapView = GMSMapView.mapWithFrame(CGRectZero, camera: camera)
self.view = mapView
mapView.delegate = self
mapView.indoorDisplay.delegate = self
mapView.myLocationEnabled = true
mapView.settings.myLocationButton = true
mapView.padding = UIEdgeInsetsMake(64, 0, 64, 0)
mapView.setMinZoom(15, maxZoom: 19)
// add Searchbar
let screenWidth = UIScreen.mainScreen().bounds.width
searchTextField = UITextField(frame: CGRectMake(16, 50, screenWidth - 32, 40))
searchTextField.delegate = self
searchTextField.placeholder = "Gebäude und Räume suchen"
searchTextField.backgroundColor = UIColor.whiteColor()
searchTextField.clearButtonMode = UITextFieldViewMode.WhileEditing
searchTextField.layer.borderWidth = 1
searchTextField.layer.borderColor = UIColor.customGrey().CGColor
searchTextField.font = UIFont.systemFontOfSize(16.0)
let showCategories = UIButton(type: .Custom)
showCategories.frame = CGRectMake(0, 0, 40, 40)
showCategories.setTitle(String.fontAwesomeIconWithCode("fa-calendar-plus-o"), forState: .Normal)
showCategories.setTitleColor(UIColor.customDarkGrey(), forState: .Normal)
showCategories.titleLabel?.font = UIFont.fontAwesomeOfSize(20)
showCategories.addTarget(self,action: "calendarAddButtonPressed",forControlEvents: UIControlEvents.TouchUpInside)
searchTextField.rightView = showCategories
searchTextField.rightViewMode = .Always
searchTextField.userInteractionEnabled = true
self.mapView.addSubview(searchTextField)
The Button works fine, but i am unable to focus on the TextField.
When ill set (in ViewDidLoad).
searchTextField.becomesFirstResponder()
The Keyboard is there.
Also that event:
func textFieldDidBeginEditing(textField: UITextField) {
print("start searching")
self.becomeFirstResponder()
}
Is not fireing.
Any ideas? When the SubView is not on the top level - the button should not work too, or?

The accepted answer didn't help me at all, but it turns out there's another question on SO that is similar, but with Objective C.
All GMSMapViews have a GMSBlockingGestureRecognizer by default, and that is why your textField isn't working the way you want it to. The solution is to remove it, so you can put this in your viewDidLoad() method:
Swift 3
for gesture in mapView.gestureRecognizers! {
mapView.removeGestureRecognizer(gesture)
}
Alternatively, if you for some reason added other gesture recognizers to the mapView, you can do this:
for (index,gesture) in mapView.gestureRecognizers!.enumerated() {
if index == 0 {
mapView.removeGestureRecognizer(gesture)
}
}
Since the GMSBlockingGestureRecognizer is added by default, it will always be the first one in the array of gesture recognizers.
Also, make sure you put the for loop somewhere it will only be called once because if it is called multiple times, you could remove other gestures unintentionally.

Ok ill found a solution for someone who is struggling with the same problems.
When you set:
self.view = mapView
It looks like that you are unable to set ANY subviews, because that Views never receive touch events.
So in that case use:
mapView = GMSMapView.mapWithFrame(self.view.bounds, camera: camera)
self.view.addSubview(mapView)
Then all SubViews work fine.
