Google地图的自定义InfoWindow-无法设置y位置

Question

我正在为我的项目使用Google地图。我需要在InfoWindow中显示带有标题的图像。为此，我创建了新的XIB。现在，除了InfoWindow的y位置，其他所有东西都可以正常工作。我无法正确设置InfoWindow的Y轴。请帮我解决这个问题。

    func mapView(_ mapView: GMSMapView, didTap marker: GMSMarker) -> Bool {
    var markerData : NSDictionary?

    if let data = marker.userData! as? NSDictionary {
        markerData = data
    }

    locationMarker = marker
    infoWindow.removeFromSuperview()
    infoWindow = loadNiB()

    guard let location = locationMarker?.position else {
        print("locationMarker is nil")
        return false
    }

    infoWindow.spotData = markerData
    infoWindow.alpha = 0.9
    infoWindow.layer.cornerRadius = 12

    let name = markerData!["name"]!
    let imageUrl = markerData!["img"]!

    infoWindow.name.text = "\(name)"

    let trimmedUrl = (imageUrl as AnyObject).trimmingCharacters(in: CharacterSet(charactersIn: "")).replacingOccurrences(of: " ", with: "%20")

    var activityLoader = UIActivityIndicatorView()
    activityLoader = UIActivityIndicatorView(style: .gray)
    activityLoader.center = infoWindow.imgMarker.center
    activityLoader.startAnimating()
    infoWindow.imgMarker.addSubview(activityLoader)

    infoWindow.imgMarker.sd_setImage(with: URL(string: trimmedUrl), completed: { (image, error, imageCacheType, imageUrl) in

        if image != nil
        {
            activityLoader.stopAnimating()
        }
        else
        {
            print("image not found")
            activityLoader.stopAnimating()
        }
    })

    // Offset the info window to be directly above the tapped marker
    infoWindow.center = mapView.projection.point(for: location)
    infoWindow.center.y = infoWindow.center.y - 82
    self.view.addSubview(infoWindow)
    return false
}

添加自定义标记时，请设置以下属性：

marker.infoWindowAnchor = CGPoint(x: 0.5, y: 0.8)

根据您的要求更改y的值。

从屏幕截图中可以看出，您似乎需要增加y值，如下所示：

infoWindow.center.y = infoWindow.center.y - 52
