Trigger when 'myLocation' button tapped (Google Maps SDK for iOS)

I want to do some stuff when 'myLocation' button tapped. So far, I've the UIButton itself:

UIButton *btnMyLoc = (UIButton*)[self.googleMapView subviews].lastObject;

But it's not enough. Any ideas?

  func didTapMyLocationButton(for mapView: GMSMapView) -> Bool {


//if want to change the camera position

            if self.latDouble != 0.0 && self.longDouble != 0.0
            {
                let camera: GMSCameraPosition = GMSCameraPosition.camera(withLatitude: self.latDouble, longitude: self.longDouble, zoom: 18.0)
                self.mapView.camera = camera

            }

             self.mapView.isMyLocationEnabled = true
            self.mapView.reloadInputViews()
            return true
        }

In release 1.9.2 there is a delegate method that does exactly that:

(BOOL) didTapMyLocationButtonForMapView: (GMSMapView *) mapView [optional]

For do any thing other you also can get reference to Location Button.

// custom target My Location Button
    for (UIView* tmpview in _mapView.subviews[1].subviews[0].subviews) {
        if ([NSStringFromClass([[tmpview class] class]) isEqualToString:@"GMSx_QTMButton"]) {
            if ([tmpview isKindOfClass:[UIButton class]]) {
                myLocationBtn = (UIButton*)tmpview;
                [myLocationBtn addTarget:self action:@selector(clickedOnLocationButton:) forControlEvents:UIControlEventTouchUpInside];
            }
        }
    }

Currently there is no direct method in Google Maps IOS sdk for knowing when the user taps on MyLocation button. A possible workaround is to use the below method

- (void) mapView: (GMSMapView *) mapView  idleAtCameraPosition: (GMSCameraPosition *)   position

This will be called at the end of any camera animation or gestures. When a user clicks mylocation button, the camera will be animated to position the visible map region such that the user's current location(if detected) will lie at the center. So you can check inside idleAtCameraPosition whether the location is same as the user's current location that can be known through - (CLLocation*) myLocation [read, assign] and do your required functionality.
