Uiview 为GMSMapview的自定义infoMarkerWindow实现添加标注

我正在使用Google IOS SDK并已实现

- (UIView *)mapView:(GMSMapView *)mapView markerInfoWindow:(GMSMarker *)marker

---

实现自定义视图。当我显示此视图时，它不会像谷歌地图视图通常为自己的标记添加标注。有人能告诉我如何才能添加指向此自定义MakerInfo窗口标记的类似标注的指针吗？

此方法是一种

GMSMapViewDelegate

方法，您是否将代理设置为视图控制器

mapView.delegate = self;

下面是如何做到这一点

- (UIView *)mapView:(GMSMapView *)mapView markerInfoWindow:(GMSMarker *)marker{
    int popupWidth = 300;
    int contentWidth = 280;
    int contentHeight = 140;
    int contentPad = 10;
    int popupHeight = 200;
    int popupBottomPadding = 16;
    int popupContentHeight = contentHeight - popupBottomPadding;
    int buttonHeight = 30;
    int anchorSize = 20;
    CLLocationCoordinate2D anchor = marker.position;
    CGPoint point = [mapView.projection pointForCoordinate:anchor];


    UIView *outerView = [[UIView alloc] initWithFrame:CGRectMake(0, 0, popupWidth, popupHeight)];
    float offSet = anchorSize * M_SQRT2;
    CGAffineTransform rotateBy45Degrees = CGAffineTransformMakeRotation(M_PI_4); //rotate by 45 degrees
    UIView *callOut = [[UIView alloc] initWithFrame:CGRectMake((popupWidth - offSet)/2.0, popupHeight - offSet, anchorSize, anchorSize)];
    callOut.transform = rotateBy45Degrees;
    callOut.backgroundColor = [UIColor blackColor];
    [outerView addSubview:callOut];

    UIView *view = [[UIView alloc] initWithFrame:CGRectMake(0, 0, popupWidth, 190)];
    [view setBackgroundColor:[UIColor whiteColor]];

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

    view.layer.borderColor = [UIColor blackColor].CGColor;
    view.layer.borderWidth = 2.0f;



    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, 80)];
    [descriptionLabel setFont:[UIFont systemFontOfSize:12.0]];
    descriptionLabel.numberOfLines = 5;
    descriptionLabel.text = [marker snippet];

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


    [outerView addSubview:view];

    return outerView;

}

是的，它显示的是自定义视图-但我的问题是如何显示谷歌为自己的标记显示的小标注标记…你有你所说的屏幕截图吗？我对您所说的标注标记有点困惑。也许你最好提供makerInforWindow方法的一些代码，这样我们就可以找出问题所在……我已经解决了，我会发布代码。我所说的是显示底部指向标记的小三角形，以提供一个视觉指示，表明此信息窗口属于此特定标记。我正在用代码创建一个小视图，并进行仿射变换，使其看起来像底部的三角形。
