Question

我目前正在使用google maps ios SDK创建并返回自定义视图，方法是将委托设置为self并使用以下代码。

#pragma mark - GMSMapViewDelegate
-(UIView*)mapView:(GMSMapView *)mapView markerInfoWindow:(id<GMSMarker>)marker {
    int popupWidth = 200;
    int contentWidth = 180;
    int contentPad = 10;
    int popupHeight = 140;
    int popupBottomPadding = 16;
    int popupContentHeight = popupHeight - popupBottomPadding;
    int buttonHeight = 30;

    UIView *outerView = [[UIView alloc] initWithFrame:CGRectMake(0, 0, popupWidth, popupHeight)];

    UIView *view = [[UIView alloc] initWithFrame:CGRectMake(0, 0, popupWidth, popupContentHeight)];
    [view setBackgroundColor:[UIColor whiteColor]];

    UILabel *titleLabel = [[UILabel alloc] initWithFrame:CGRectMake(contentPad, 0, contentWidth, 22)];
    [titleLabel setFont:[UIFont systemFontOfSize:17.0]];
    titleLabel.text = [marker title];

    UILabel *descriptionLabel = [[UILabel alloc] initWithFrame:CGRectMake(contentPad, 24, contentWidth, 20)];
    [descriptionLabel setFont:[UIFont systemFontOfSize:11.0]];
    descriptionLabel.text = [marker snippet];

    [view addSubview:titleLabel];
    [view addSubview:descriptionLabel];

    UIButton *directionButton = [UIButton buttonWithType:UIButtonTypeRoundedRect];
    directionButton.frame = CGRectMake(contentPad, 45, contentWidth, buttonHeight);
    [directionButton setTitle:@"Directions" forState:UIControlStateNormal];
    [directionButton addTarget:self action:@selector(directionsPressed) forControlEvents:UIControlEventTouchDown];

    UIButton *viewLocationButton = [UIButton buttonWithType:UIButtonTypeRoundedRect];
    [viewLocationButton addTarget:self action:@selector(viewLocationPressed) forControlEvents:UIControlEventTouchUpInside];
    [viewLocationButton setTitle:@"View Location" forState:UIControlStateNormal];
    viewLocationButton.frame = CGRectMake(contentPad, 80, contentWidth, buttonHeight);

    // handle bottom dealio
    UIImage *bottomImage = [UIImage imageNamed:@"map-pointer-bottom"];
    UIImageView *bottomView = [[UIImageView alloc] initWithFrame:CGRectMake((popupWidth / 2) - (bottomImage.size.width / 2), (popupContentHeight), bottomImage.size.width, bottomImage.size.height)];
    [bottomView setImage:bottomImage];

    [outerView addSubview:view];
    [outerView addSubview:bottomView];
    [outerView addSubview:directionButton];
    [outerView addSubview:viewLocationButton];

    ListItem *li = (ListItem*)[marker userData];
    self.currentItem = li;
    NSLog(@"List Item %@ - %@", li.type, li.typeid);

    return outerView;
}

-(void)directionsPressed {
    NSLog(@"Directions Pressed");
}

-(void)viewLocationPressed {
    NSLog(@"Location View Pressed");
}

- (void)mapView:(GMSMapView *)mapView didTapInfoWindowOfMarker:(id<GMSMarker>)marker {
    NSLog(@"Tap Captured");
}

当我点击自定义视图时，didTapWindowOfMarker被触发，但是没有触发按钮的目标方法。

为什么会出现这种情况的想法？

Answer 1

正如Google Maps Android API文档中正式提到的，以下关于 infowindows 的限制也适用于Google Maps iOS SDK：

信息窗口不是实时视图，而是视图在地图上呈现为图像。因此，您在视图上设置的任何侦听器都将被忽略，并且您无法区分视图各个部分上的单击事件。建议您不要在自定义信息窗口中放置交互式组件（如按钮，复选框或文本输入）。

所以基本上点击infowindow的任何部分只会触发“ didTapWindowOfMarker ”

Answer 2

Swift 3.0解决方案

 //empty the default infowindow
        func mapView(_ mapView: GMSMapView, markerInfoWindow marker: GMSMarker) -> UIView? {
            return UIView()
        }

        // reset custom infowindow whenever marker is tapped
        func mapView(_ mapView: GMSMapView, didTap marker: GMSMarker) -> Bool {

            customInfoView.removeFromSuperview()
        //    customInfoView.button.addTarget(self, action: #selector(buttonTapped(_:)), for: .touchUpInside)
            self.view.addSubview(customInfoView)

            // Remember to return false
            // so marker event is still handled by delegate
            return false
        }

        // let the custom infowindow follows the camera
        func mapView(_ mapView: GMSMapView, didChange position: GMSCameraPosition) {
            if (locationMarker != nil){
                let location = locationMarker.position
                customInfoView.center = mapView.projection.point(for: location)
            }
        }

        // take care of the close event
        func mapView(_ mapView: GMSMapView, didTapAt coordinate: CLLocationCoordinate2D) {
            customInfoView.removeFromSuperview()
        }

并将此视图（customInfoWindow）的出口放在具有mapView的同一控制器中。

，我从这个链接中得到了这个想法

Answer 3

我有一个UView，我正在为视图添加一个委托，以便UIButton调用一个选择器。对于谷歌地图，我打电话

时什么都不做

- (void) mapView:(GMSMapView *)mapView didTapInfoWindowOfMarker:(GMSMarker *)marker;

但是，我将我的infowindow（我的自定义视图）委托设置为self，并在按下链接到选择器的按钮时调用我的所有操作。

<强>更新

以下是我使用的代码，用于检测添加到infoWindows的按钮。我创建了一个带有2个假按钮的自定义infoWindow（它们实际上可以替换为图像因为它们不会触发任何动作）并且我在infoWindow上添加了一个完全透明的覆盖图，其中包含2个真正的按钮。这些按钮将触发操作。

我使用一些委托方法或KVC，以便在移动infoWindow时移动叠加层。

- (UIView *)mapView:(GMSMapView *)mapView markerInfoWindow:(GMSMarker *)marker {
    [self.actionOverlayCalloutView removeFromSuperview];
    UIView *calloutView = [[UIView alloc] initWithFrame:CGRectMake(0, 0, infoWindowWidth, infoWindowHeight)];

    float offset = anchorSize * M_SQRT2;
    CGAffineTransform rotateBy45Degrees = CGAffineTransformMakeRotation(M_PI_4);
    UIView *arrow = [[UIView alloc] initWithFrame:CGRectMake((infoWindowWidth - anchorSize)/2.0, infoWindowHeight - offset, anchorSize, anchorSize)];
    arrow.transform = rotateBy45Degrees;
    arrow.backgroundColor = [UIColor lightGrayColor];
    [calloutView addSubview:arrow];

    UIView *contentView = [[UIView alloc] initWithFrame:CGRectMake(0, 0, infoWindowWidth, infoWindowHeight - offset/2)];
    [contentView setBackgroundColor:[UIColor whiteColor]];

    contentView.layer.cornerRadius = 5;
    contentView.layer.masksToBounds = YES;

    contentView.layer.borderColor = [UIColor lightGrayColor].CGColor;
    contentView.layer.borderWidth = 1.0f;

    self.actionOverlayCalloutView =
    [NSKeyedUnarchiver unarchiveObjectWithData:[NSKeyedArchiver archivedDataWithRootObject:contentView]]; //hack to copy a view...
    self.actionOverlayCalloutView.backgroundColor = [UIColor lightGrayColorWithAlpha:0.5];
    self.actionOverlayCalloutView.layer.cornerRadius = 5;
    NSMutableArray *falseButtons = [NSMutableArray array];
    NSMutableArray *actionButtons = [NSMutableArray array];
    PointMapItem *pointAnnotation = marker.userData;
    if ([pointAnnotation canPerformSend]) {
        UIButton *button = [[UIButton alloc] init];
        [button setImage:[UIImage imageNamed:@"imageButton1.png"] forState:UIControlStateNormal];
        [falseButtons addObject:button];
        UIButton *activableButton = [[UIButton alloc] init];
        [activableButton addTarget:self action:@selector(onButton1Clicked) forControlEvents:UIControlEventTouchUpInside];
        [actionButtons addObject:activableButton];
    }
    if ([pointAnnotation canPerformShowDetails]) {
        UIButton *button = [[UIButton alloc] init];
        [button setImage:[UIImage imageNamed:@"imageButton1.png"] forState:UIControlStateNormal];
        [falseButtons addObject:button];
        UIButton *activableButton = [[UIButton alloc] init];
        [activableButton addTarget:self action:@selector(onButton2Clicked) forControlEvents:UIControlEventTouchUpInside];
        [actionButtons addObject:activableButton];
    }
    int buttonWidth = contentView.frame.size.width / [falseButtons count];
    int currentOffset = 0;
    for (int i=0; i<falseButtons.count; i++) {
        UIButton *falseButton = [falseButtons objectAtIndex:i];
        UIButton *activableButton = [actionButtons objectAtIndex:i];
        [falseButton setFrame:CGRectMake(currentOffset, 0, buttonWidth, contentView.frame.size.height)];
        currentOffset += buttonWidth;
        activableButton.frame = falseButton.frame;
        [activableButton setTitle:@"" forState:UIControlStateNormal];
        [self.actionOverlayCalloutView addSubview:activableButton];
        [contentView addSubview:falseButton];
    }
    [calloutView addSubview:contentView];

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

    [self.mapView addSubview:self.actionOverlayCalloutView];
    return calloutView;
}

- (void)mapView:(GMSMapView *)pMapView didChangeCameraPosition:(GMSCameraPosition *)position {
    if (pMapView.selectedMarker != nil && self.actionOverlayCalloutView.superview) {
        CLLocationCoordinate2D anchor = [self.mapView.selectedMarker position];
        CGPoint point = [self.mapView.projection pointForCoordinate:anchor];
        float offset = anchorSize * M_SQRT2;
        point.y -= self.mapView.selectedMarker.icon.size.height + offset/2 + (infoWindowHeight - offset/2)/2;
        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 (!self.mapView.selectedMarker) {
            [self.actionOverlayCalloutView removeFromSuperview];
        }
    }
}

- (void)onButton2Clicked {
    //your code
    self.mapView.selectedMarker = nil;
}

- (void)onButton1Clicked {
    // your code;
    self.mapView.selectedMarker = nil;
}

Answer 5

1）创建一个要在infoWindow中显示的子视图。

2）设置子视图的帧等于infoWindow视图的帧。

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

添加按钮到markerInfoWindow委托方法返回的视图
