我在 iPhone 上从 Xcode 运行我的应用程序时遇到问题。该应用程序在模拟器(iPhone、iPad 等)中(看似)运行良好。它在 iPhone4 或 iPad2 上加载时也运行良好，仅当尝试从 Xcode(版本 4.5)启动应用程序时，我从 Xcode 收到以下消息:无法启动“”未能获得进程 1024 的任务”， Xcode 输出窗口中的唯一消息是:
error: failed to launch '/private/var/mobile/Applications/36159066-FEDB-4A26-A05D-E599F397074A/MetriScan.app' -- failed to get the task for process 1024`
iPhone 上没有崩溃日志，但控制台日志包含以下内容(运行前清除):

不幸的是，我没有从日志中得到太多 :) 但我很好奇关于 Max open files 的第一行，这是一个问题吗。
我感觉问题出在 Info.plist 上，但我不知道从哪里开始。
我应该提一下，它在大约一个月前一直运行良好，这是我的最后一个工作备份，我看不出那个和下一个非工作备份之间的代码有任何区别。我主要在模拟器中运行代码或通过 iTunes 直接加载到我的测试设备中，这就是我花了这么长时间才发现问题的原因。从那时起我就一直致力于本地化工作，也许这就是问题所在？
我用谷歌搜索了这个问题，但没有找到任何似乎适用的东西，我重新启动了 iPhone 和 iMac，当然还删除了介于两者之间的 iPhone 上的应用程序。
如有任何帮助和指点，我们将不胜感激。
最佳答案
事实证明这是一个代码签名问题。不久前，我在将 iPad 3 添加到我的临时分发测试设备时遇到了问题，我更改了登录代码以尝试使其正常工作。那是一个 iOS 分发证书，我现在必须将其改回开发人员证书才能从 Xcode 运行 iPhone。从这里可以清楚地看出，我确实没有完全理解整个代码签名和分发过程。
但它再次起作用，太棒了。
关于ios - 从 Xcode 在 iPhone4 上运行应用程序失败，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/13127796/
