谷歌地图iOS SDK在RubyMotion中崩溃

我有一个内置于RubyMotion的iOS应用程序（使用推广框架）。我正在尝试加载一个仅仅是谷歌地图视图（GMSMapView）的视图——他们的，当应用程序第一次安装在设备或模拟器上时，它可以很好地加载，但在那之后，每次都会立即崩溃；或者即使该屏幕已关闭，然后在不关闭应用程序的情况下重新打开

代码只是Google的“Hello World”示例，我的头撞到了墙上。下面是我的代码，除了尝试将其作为升级屏幕外，我还尝试通过子类化一个新的UIViewController来实现这一点，并得到了相同的错误

我的代码：

class-MapScreen

下面是crashlog的相关部分：

这让我抓狂，任何帮助都将不胜感激

您的标记正在丢失其引用并被垃圾回收。试试ivar：

class MapScreen < PM::Screen

  def on_load
    camera = GMSCameraPosition.cameraWithLatitude(-33.868, longitude: 151.2086, zoom: 6)
    mapView = GMSMapView.mapWithFrame(CGRectZero, camera:camera)

    @marker = GMSMarker.new
    @marker.position = camera.target
    @marker.snippet = "Hello World"
    @marker.appearAnimation = 1
    @marker.map = mapView

    mapView.delegate = self
    # self.view = mapView
    self.view.addSubview(mapView)
  end

end

class-MapScreen

谢谢，但不幸的是，它仍然在同一位置给我带来了同样的问题，崩溃日志中也有同样的错误。
