多次加载VR视频

Question

我使用Swift实现了一些适用于iOS的GoogleVR，除了我多次播放视频时，转换视图仅在第一次显示时，它运行良好。我怎么强迫总是显示这个过渡视图？

let url = NSURL.fileURL(withPath: self.urlPost!)

videoVRView.load(from: url)
videoVRView.enableCardboardButton = true
videoVRView.enableFullscreenButton = true
videoVRView.enableInfoButton = false
videoVRView.hidesTransitionView = false
videoVRView.delegate = self

self.videoVRView.hidesTransitionView = false
self.videoVRView.displayMode =  GVRWidgetDisplayMode.fullscreenVR
self.currentDisplayMode =   GVRWidgetDisplayMode.fullscreenVR

if isPaused {
    videoVRView?.play()
} else {
    videoVRView?.pause()
}
