Is there a way to center the orange arrow (a GMSMapMarker) in a coordinate, changing the view frame or something? I'm using Google Maps for iOS. I can rotate the view with an angle, but I want to set the view's center in a custom coordinate.
有没有办法将橙色箭头（GMSMapMarker）置于坐标中心，更改视图框架等？我正在使用Google Maps for iOS。我可以用一个角度旋转视图，但我想在自定义坐标中设置视图的中心。

I found the solution using the property groundAnchor of GMSMarker:
我使用GMSMarker的属性groundAnchor找到了解决方案：
_mapMarker.groundAnchor = CGPointMake(0.5,0.5);
_mapMarker.groundAnchor = CGPointMake（0.5,0.5）;

I think you can calculate the pixel/degree by using the GMSCoordinateBounds, then you can shift the center bases on your icon size and heading.
我认为您可以使用GMSCoordinateBounds计算像素/度数，然后您可以根据图标大小和标题移动中心。
