Nativescript ios 中闪屏后显示白屏

在 Nativescript ios 中，启动屏幕后几秒钟显示白屏。这种情况仅发生在我们的项目中，但示例项目运行良好。我检查了模拟器和 iPhone 5、iPhone 6、iPad mini，所有设备都显示白屏。我将 Nativescript 与 Angular 4 一起使用，这里我包含了我的 package.json

我不知道问题是什么以及如何解决它。所以请你=帮助我。

您应该重复启动屏幕的布局或稍微不同的版本（带有微调器和加载...消息）硬编码，一旦应用程序实际加载，就会被删除或绘制。这将在启动屏幕和加载的应用程序之间提供平滑且专业的过渡。
