An Unknown Error occurred in Xcode
提问by user3728320
I'm trying to test out my app on my ipad and when I decide to run it on my ipad, Xcode says that it's successfully built. On the top, it says that it's runnning the app, but nothing happens for 2-3 minutes. Finally, I get two screens popping up saying "An unknown error occurred." I have tried running other apps through Xcode on my ipad and they work fine. I also decided to exit Xcode and restart everything, but the problem still exists. Does anyone know what the problem is?
我正在尝试在 ipad 上测试我的应用程序，当我决定在 ipad 上运行它时，Xcode 说它已成功构建。在顶部，它说它正在运行应用程序，但在 2-3 分钟内没有任何反应。最后，我弹出两个屏幕，说“发生未知错误”。我曾尝试在 ipad 上通过 Xcode 运行其他应用程序，它们运行良好。我也决定退出Xcode并重新启动一切，但问题仍然存在。有谁知道问题是什么？
Not sure if this will be useful but Xcode Version: 5.1.1 Ipad Version: 7.0.4 Mac OS X 10.9

First, delete the app from your device and then restart the xcode by force quit and then again open it. Now clean your project and run the project in your device. Now it will be run without any issue.
首先，从您的设备中删除该应用程序，然后通过强制退出重新启动 xcode，然后再次打开它。现在清理您的项目并在您的设备中运行该项目。现在它将毫无问题地运行。

Close your simulator or unplug and plug back in your device, and re-select the device target.
