xcode模拟器在尝试测试不同的故事情节时不断改变硬件设备模式

Question

我的模拟器有些奇怪，我希望有人能帮助我。下面的代码在我的 AppDelegate 中。根据正在运行的设备，我有不同的 Storyboard。设备检测代码似乎工作正常，但我在将模拟器硬件->设备保持在我想要的位置时遇到了问题。

1. 项目设置为“通用”，模拟器设置为苹果手机。模拟器将自己更改为 iPhone 模拟器并作为 iPhone 运行。
2. iPad 的项目设置，iPad 的模拟器，作为 iPad 运行。放项目回到通用，模拟器回到 iPhone，模拟器将自身重置回 iPad 并将代码作为 iPad 运行。
3. 将项目设置为 iPhone，将模拟器留在 iPad 上。运行为iPad 上的 iPhone 应用程序？？

....以及多种不同的变体。尝试多次重启 Mac 和 xcode，但没有效果。如果我重置模拟器并在模拟器上运行项目图标而不是通过 xcode，模拟器将保持我放入的硬件模式。有什么想法吗？？

如果我正确理解了您的问题，那么您遇到的问题是您在模拟器中将您的应用程序作为 iPad 运行时遇到困难，因为它不断变回 iPhone。这是因为您需要在顶部工具栏中选择要在 Xcode 中运行该应用程序的模拟器:

完成后，点击运行，您选择的 iOS 模拟器应该会打开并运行您的应用。
