Adding Click Event on InfoWindow/Marker in Google Maps SDK for native iOS/objective C

问题

Simple Question

I´m working on an App for iOS where I embedded the new Google Map for native iOS. Everything works fine except one problem where I can´t find a propper solution for native IOS/ Objective-C neither here nor at google (if there is one please show me and sorry for annoying you)

What I want: I want the User to Click on the Marker that opens the Info Window. After If he clicks or taps on the Info Window it should open a New UIView with further Informations.

How can I do that?

Thanks for advices

回答1:

1.conform to the GMSMapViewDelegate protocol.

@interface YourViewController () <GMSMapViewDelegate>
// your properties
@end

2.set your mapView_ delegate.

mapView_.delegate = self;

3.implement the GMSMapViewDelegate method

- (void)mapView:(GMSMapView *)mapView didTapInfoWindowOfMarker:(GMSMarker *)marker {
    // your code
}

btw, marker.userData is useful. you can set your needed data into it and use it in - mapView:didTapInfoWindowOfMarker:

回答2:

where you adding Map,add

 mapView_.delegate=self; 

then use this

-(void)mapView:(GMSMapView *)mapView
didTapInfoWindowOfMarker:(id<GMSMarker>)marker{

   //info window tapped

}

回答3:

a full answer for swift 4

1. add GMSMapViewDelegate as delegate

2. set yourmap delegate like this : googlemap.delegate = self

3. add this func

func mapView(_ mapView: GMSMapView, didTap marker: GMSMarker) -> Bool 
            {
               // do something
                return true
            }

I am using Google Maps SDK for iOS.

I have subclassed uiview to create a custom view "InfoWindow" for infowindow.

add @property (nonatomic,retain) UIView *actionOverlayCalloutView; in your viewcontroller's header file.

- (UIView *)mapView:(GMSMapView *)mapView markerInfoWindow:(GMSMarker *)marker {
if(self.objSelectedParking != nil)
{
    float anchorSize = 0.5f;
    float infoWindowWidth = 250.0f;
    float infoWindowHeight = 250.0f;

    [self.actionOverlayCalloutView removeFromSuperview];
    InfoWindow *infoWindow = [[InfoWindow alloc] initWithFrame:CGRectMake(0, 0, infoWindowWidth, infoWindowHeight)];
    infoWindow.lblTitle.text = self.objSelectedParking.strParkingName;
    infoWindow.lblDescription.text = self.objSelectedParking.strParkingDescription;
    infoWindow.lblAddress.text = self.objSelectedParking.strParkingAddress;
    infoWindow.lblPhone.text = self.objSelectedParking.strParkingPhone;
    infoWindow.imageViewParking.image = [UIImage imageNamed:@"parking_image_sample.jpg"];

    float offset = anchorSize * M_SQRT2;

    self.actionOverlayCalloutView = [[UIView alloc] initWithFrame:CGRectMake(0, 0, infoWindowWidth, infoWindowHeight - offset/2)];
    [self.actionOverlayCalloutView setBackgroundColor:[UIColor clearColor]];

    self.actionOverlayCalloutView.layer.cornerRadius = 5;
    self.actionOverlayCalloutView.layer.masksToBounds = YES;

    UIButton *hiddenCloseButton = [[UIButton alloc] initWithFrame:CGRectMake((infoWindow.viewContainer.frame.origin.x + infoWindow.viewContainer.frame.size.width - 30), 10, 20, 20)];
    [hiddenCloseButton addTarget:self action:@selector(hiddenCloseButtonClickedInInfowindow:) forControlEvents:UIControlEventTouchUpInside];
    [self.actionOverlayCalloutView addSubview:hiddenCloseButton];

    UIButton *hiddenDirectionButton = [[UIButton alloc] initWithFrame:CGRectMake((infoWindow.lblAddress.frame.origin.x + infoWindow.lblAddress.frame.size.width + 5), (infoWindow.lblAddress.frame.origin.y - 15), 25, 25)];
    [hiddenDirectionButton addTarget:self action:@selector(hiddenDirectionButtonClickedInInfowindow:) forControlEvents:UIControlEventTouchUpInside];
    [self.actionOverlayCalloutView addSubview:hiddenDirectionButton];

    UIButton *hiddenInfoButton = [[UIButton alloc] initWithFrame:CGRectMake((infoWindow.innerContainerView.frame.origin.x + infoWindow.imageViewParking.frame.origin.x + infoWindow.imageViewParking.frame.size.width + 20), (infoWindow.innerContainerView.frame.origin.y + 25), 25, 25)];
    [hiddenInfoButton addTarget:self action:@selector(hiddenInfoButtonClickedInInfowindow:) forControlEvents:UIControlEventTouchUpInside];
    [self.actionOverlayCalloutView addSubview:hiddenInfoButton];

    UIButton *hiddenScheduleButton = [[UIButton alloc] initWithFrame:CGRectMake((infoWindow.innerContainerView.frame.origin.x + infoWindow.verticalLineSeperatorView.frame.origin.x + infoWindow.verticalLineSeperatorView.frame.size.width + 10), (infoWindow.innerContainerView.frame.origin.y + 25), 25, 25)];
    [hiddenScheduleButton addTarget:self action:@selector(hiddenScheduleButtonClickedInInfowindow:) forControlEvents:UIControlEventTouchUpInside];
    [self.actionOverlayCalloutView addSubview:hiddenScheduleButton];

    [infoWindow addSubview:self.actionOverlayCalloutView];

    CLLocationCoordinate2D anchor = [_mapView.selectedMarker position];
    CGPoint point = [_mapView.projection pointForCoordinate:anchor];
    point.y -= _mapView.selectedMarker.icon.size.height + offset/2 + (infoWindowHeight - offset/2)/2;
    self.actionOverlayCalloutView.center = point;

    [_mapView addSubview:self.actionOverlayCalloutView];
    return infoWindow;
}

return nil;
}

-(void)mapView:(GMSMapView *)pMapView didChangeCameraPosition:(GMSCameraPosition *)position {
if (pMapView.selectedMarker != nil && self.actionOverlayCalloutView.superview)
{
    float anchorSize = 0.5f;
    float infoWindowHeight = 250.0f;

    CLLocationCoordinate2D anchor = [_mapView.selectedMarker position];
    CGPoint point = [_mapView.projection pointForCoordinate:anchor];
    float offset = anchorSize * M_SQRT2;
    point.y -= _mapView.selectedMarker.icon.size.height + offset/2 + (infoWindowHeight - offset/2)/2;
    point.y = point.y - 10; //PRATIK GUJARATI CODE TO ADJUST HEIGHT AND Y VALUE OF TRANSPARENT OVERLAY VIEW
    self.actionOverlayCalloutView.center = point;
} else {
    [self.actionOverlayCalloutView removeFromSuperview];
}
}

- (void)mapView:(GMSMapView *)mapView didTapAtCoordinate:(CLLocationCoordinate2D)coordinate {
[self.actionOverlayCalloutView removeFromSuperview];
}

- (void)observeValueForKeyPath:(NSString *)keyPath ofObject:(id)object change:(NSDictionary *)change context:(void *)context {
if ([keyPath isEqualToString:@"mapView.selectedMarker"]) {
    if (!_mapView.selectedMarker) {
        [self.actionOverlayCalloutView removeFromSuperview];
    }
}
}

回答5:

1. Create one subview which you want to show in infoWindow.

2. Set frame of subview equals to frame of infoWindow view.

   subView = [[[NSBundle mainBundle] loadNibNamed:@"viewName" owner:self options:nil] objectAtIndex:0]; 
   [subView setFrame:infoview.frame]; 
   [self.mapview addSubview:subView];
   

回答6:

get information at google map view information

    func mapView(_ mapView: GMSMapView, didTapInfoWindowOf marker: GMSMarker) {
    print(marker.title!)
    print(marker.snippet!)
}
