Ios 谷歌VR播放器SDK（GVRSDK）默认以carboard模式启动？

我希望能够在纸板模式下启动我的应用程序上的视频

我已经成功安装了Gooogle VR player SDK，我创建了一个按钮以全屏模式启动视频，也成功了

我想要另一个按钮，这次开始在纸板模式的视频，但我不能使它的工作

下面是带有按钮的控制器的代码：

  }

我做了与开始以全屏模式播放视频相同的过程，但调用了GVRCardboardView而不是您可以看到的GVRVideoView，但它不起作用。。。我在这些线路上有错误：

      cardboardVRview.load(from: URL(string: Media.videoURL))
    cardboardVRview.enableCardboardButton = true
    cardboardVRview.enableFullscreenButton = true

对于第一行，“静态成员”load不能在GVRCardboardView类型的实例中使用

类型为“GVRCardboardView”的值没有其他两行的成员“enableFullscreenButton”和“enableCardboardBUtton”

有人知道我怎样才能做到这一点吗

太棒了！谢谢你们

如果您希望在默认情况下以硬纸板模式启动。您应该将视图设置为这样。意味着你将进入：

videoVRView.displayMode = GVRWidgetDisplayMode.fullscreenVR
