Google Maps iOS SDK move “My Location” button to bottom left hand corner

Question

Using the Google Maps for iOS SDK, the \"My Location\" button is by default placed in the bottom right hand corner:

Answer 1

for (UIView *object in _mapView.subviews) {
    if([[[object class] description] isEqualToString:@"GMSUISettingsPaddingView"] )
    {
        for (UIView *settingView in object.subviews) {
            if([[[settingView class] description] isEqualToString:@"GMSUISettingsView"] )
            {
                for(UIView *view in settingView.subviews) {
                    if([[[view class] description] isEqualToString:@"GMSx_QTMButton"] ) {
                        CGRect frame = view.frame;
                        frame.origin.y -= 60;
                        view.frame = frame;
                    }
                }
            }
        };

    }
}

You can use the padding of the GMSMapView.

GMSCameraPosition *camera = [GMSCameraPosition cameraWithLatitude:-37.81969
                                                        longitude:144.966085
                                                             zoom:4];
_mapView = [GMSMapView mapWithFrame:CGRectZero camera:camera];

_mapView.settings.myLocationButton = YES;
_mapView.myLocationEnabled = YES;
_mapView.padding = UIEdgeInsetsMake(0, 0, kOverlayHeight, 0);
self.view = _mapView;

SWIFT 3

self._mapView.padding = UIEdgeInsets(top: 0, left: 0, bottom: 10, right: 0)

for (UIView *object in mapView_.subviews) {
    if([[[object class] description] isEqualToString:@"GMSUISettingsView"] )
    {
        for(UIView *view in object.subviews) {
            if([[[view class] description] isEqualToString:@"UIButton"] ) {
                CGRect frame = view.frame;
                frame.origin.y -= 60;
                view.frame = frame;
            }
        }

    }
};

in swift 3 xcode 8

func moveLocationButton() -> Void{
     for object in mapView.subviews{
        for obj in object.subviews{
           if let button = obj as? UIButton{
             let name = button.accessibilityIdentifier
                if(name == "my_location"){
                        //config a position
                        button.center = self.view.center 
                    }
                }
            }
        }
    }

Answer 5

The easiest way to solve this is to change the frame and autoresizing mask of the button right after the map view is created.

UIButton* myLocationButton = (UIButton*)[[mapView_ subviews] lastObject];
myLocationButton.autoresizingMask = UIViewAutoresizingFlexibleRightMargin|UIViewAutoresizingFlexibleTopMargin;
CGRect frame = myLocationButton.frame;
frame.origin.x = 5;
myLocationButton.frame = frame;

EDIT: Sorry, I placed the button in the top right corner. Updated my code to place it in the bottom left hand corner.

Note: there is currently no API from Google to get the location button. The first line may not work in future releases of the SDK.

You also should create a feature request here.

Another option is to create the button yourself and add it as a subview to the map. The button handler code is fairly easy:

  CLLocation *location = mapView_.myLocation;
  if (location) {
    [mapView_ animateToLocation:location.coordinate];
  }

As of July 2015, this is a way to do it:

for (UIView *object in mapView_.subviews) {
    if([[[object class] description] isEqualToString:@"GMSUISettingsView"] )
    {
        for(UIView *view in object.subviews) {
            if([[[view class] description] isEqualToString:@"GMSx_QTMButton"] ) {
                CGRect frame = view.frame;
                frame.origin.y -= 60;
                view.frame = frame;
            }
        }

    }
};
