在尝试测试不同的故事情节时，xcode模拟器会不断更改硬件设备模式

Question

我对我的模拟器有些奇怪，我希望有人可以帮助我。下面的代码在我的AppDelegate中。我有不同的故事板，具体取决于正在运行的设备。设备检测代码似乎工作正常，但我在将模拟器硬件 - >设备保存到我想要的地方时遇到了问题。

1. 项目设置是＆＃39; Universal＆＃39;并将模拟器设置为 苹果手机。模拟器将自己更改为iPhone模拟器 并以iPhone身份运行。
2. 项目设置为iPad，模拟器设置为iPad，以iPad运行。组 项目回到通用，模拟器回到iPhone，模拟器 重置为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。作为一个运行 iPad上的iPhone应用程序??

....和多种不同的变化。尝试多次重启Mac和xcode，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，那么模拟器将保持在我放入的硬件模式中。有任何想法吗？

如果我正确地理解了您的问题，那么您遇到的问题是您在iPad模拟器中运行应用程序时遇到困难，因为它不断变回iPhone。这是因为您需要在顶部工具栏的Xcode中选择要运行应用程序的模拟器：

执行此操作后，单击“运行”，您选择的iOS模拟器应该打开并运行您的应用程序。
