【问题描述】：
自从升级到 Xcode 4.2 和 iOS 5 后，我无法再在我的 iPhone 上运行我的应用程序。他们仍然在模拟器中运行良好。 我正在使用带有 4.2 的 Snow Leopard，并认为这可能是问题，所以升级到 Lion，然后将 Xcode 升级到 4.2.1 Lion 版本。然而这并没有解决问题。 我已经通过许多线程试图找到类似的东西但不能。我还尝试了不同的构建设置、编译器、部署目标等。 我很确定这不是配置问题，因为应用程序加载到设备上，只是它们永远不会正确启动，如果应用程序有启动图像，这就是它锁定的地方。我也试过只运行默认的 Xcode 模板，但无济于事。 我尝试删除派生数据、清理项目、删除然后从项目中重新导入框架，但没有任何变化。
这些是我遇到的错误

然后我得到一堆这些，它们持续了 15 行

然后我得到了一堆这些你可能会想到的框架，然后是一些

所以我的猜测是（我可能是错的）看起来 Xcode 不知道框架在哪里，但只有在我的设备连接时才知道。我不知道如何解决这个问题，非常感谢任何帮助或想法 谢谢
【问题讨论】：
-
我会检查目录
/Developer/Platforms/iPhoneOS.platform/DeviceSupport/5.0.1 (9A405)是否存在。 -
谢谢我今晚去查，如果不是怎么办？
-
那你安装有问题。在这种情况下，我会尝试重新安装 Xcode 和最新的 SDK。
-
嘿 Dasdom 那个文件夹存在，它包含一个名为 Symbols 的文件夹，它应该包含更多吗？ Symbols 里面还有两个文件夹“Developer”和“System”和“usr”。它是否应该包含实际文件。我已经重新安装了两次最新的 SDK，一次是给 Leopard，一次是给 Lion，但我会再试一次，我别无选择。

嘿，谢谢你的帮助 Dasdom，虽然事实证明我需要完全卸载，而不是像我一直在做的那样重新安装，你建议
