【问题描述】：
我在使用 GCK 时遇到了一些生产问题。在模拟器上一切正常，但是当我在真实设备上构建时，什么都没有。
起初，我以为是签名或功能问题，但我是一名注册开发人员，并且权利文件包含 Google Cast SDK 所需的功能。
我已按照本设置指南的每个步骤进行操作。

记录器已启用，输出如下：

2019-10-08 11:26:39.794589-0400 od-cast-ios[1861:488951] [TableView] Warning once only: UITableView was told to layout its visible cells and other contents without being in the view hierarchy (the table view or one of its superviews has not been added to a window). This may cause bugs by forcing views inside the table view to load and perform layout without accurate information (e.g. table view bounds, trait collection, layout margins, safe area insets, etc), and will also cause unnecessary performance overhead due to extra layout passes. Make a symbolic breakpoint at UITableViewAlertForLayoutOutsideViewHierarchy to catch this in the debugger and see what caused this to occur, so you can avoid this action altogether if possible, or defer it until the table view has been added to a window. Table view: <UITableView: 0x11e0ba000; frame = (0 90; 375 722); clipsToBounds = YES; autoresize = RM+BM; gestureRecognizers = <NSArray: 0x282866730>; layer = <CALayer: 0x282644dc0>; contentOffset: {0, 0}; contentSize: {375, 836}; adjustedContentInset: {0, 0, 0, 0}; dataSource: <od_cast_ios.EpisodeViewController: 0x11dd03d50>>

另外，我正在使用 GoogleCast 框架版本 4.4.1.24 并在 iOS 13 上构建。
在模拟器上，一切运行正常，显示投射按钮并发现 Chromecast 设备。
但是当我在我的设备上构建应用程序时，按钮没有被实例化。
如果我找不到解决方案，我可能会在接下来的几个小时内发疯:(
