从 Xcode 在 iPhone4 上运行应用程序失败

Running App on iPhone4 from Xcode fails

提问by bjarne

I have a problem when running my App on my iPhone from Xcode. The App runs (seemingly) fine in the simulators (iPhone, iPad, etc). It also runs fine when loaded on the iPhone4 or iPad2, it is only when trying to start the App from Xcode (version 4.5) that I get the following message from Xcode: Could not launch "" failed to get task for process 1024", and the only message in the Xcode output windows is:

从 Xcode 在我的 iPhone 上运行我的应用程序时出现问题。该应用程序（看似）在模拟器（iPhone、iPad 等）中运行良好。它在 iPhone4 或 iPad2 上加载时也能正常运行，只有在尝试从 Xcode（4.5 版）启动应用程序时，我才从 Xcode 收到以下消息：无法启动“”无法获取进程 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`

There is no crash log on the iPhone, but the console log contains the following (cleared before the run):

iPhone上没有crash log，但是console log包含以下内容（运行前清空）：

Unfortunately, I don't get much out of the log :) But I am curious about the first line about Max open files, is that a problem.

不幸的是，我没有从日志中得到太多信息:) 但我对关于 Max open files 的第一行很好奇，这是一个问题。

I have a feeling that the problem somehow is with the Info.plist but I don't know where to start.

我有一种感觉，问题出在 Info.plist 上，但我不知道从哪里开始。

I should mention that it used to work fine up until about a month ago, my last working backup, and I can't see any difference in the code between that and the next non-working backup. I mostly run the code in the simulator or loaded directly in my test devices through iTunes, that is why it took me so long to discover the problem. I have been working on localization since that time and maybe that is where the problem crept in?

我应该提一下，直到大约一个月前，我的上次工作备份之前它都可以正常工作，而且我看不出该备份与下一次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，这就是为什么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，也许这就是问题所在？

I googled the problem, but did not come up with anything that seemed to apply, and I have re-booted the iPhone and the iMac, and of course deleted the App from the iPhone in between.

我在谷歌上搜索了这个问题，但没有找到任何似乎适用的东西，我重新启动了 iPhone 和 iMac，当然也从 iPhone 中删除了应用程序。

Any help and pointers would be greatly appreciated.

任何帮助和指示将不胜感激。

It turns out it was a code signing issue. A while back I was having problems adding an iPad 3 to my test devices for Adhoc distribution, and I changed the code signing in trying to make that work. That was an iOS distribution certificate and I had to now change that back to a developer certificate to run the iPhone from Xcode. What is clear from this is that I really don't fully understand the whole code signing and distribution process.

事实证明这是一个代码签名问题。不久前，我在将 iPad 3 添加到我的测试设备以进行 Adhoc 分发时遇到问题，我更改了代码签名以尝试使其工作。那是一个 iOS 分发证书，我现在必须将它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，我真的不完全了解整个代码签名和分发过程。

But it works again, so great.

但它又起作用了，太棒了。

i suspected it was a code signing thing too from making a distribution build. it also came with an xcode error "no provisioning profiles available" so i switched my build scheme back to "debug" and that seemed to fixed it.

我怀疑这也是一个发行版构建的代码签名问题。它还带有一个 xcode 错误“没有可用的配置文件”，所以我将我的构建方案切换回“调试”，这似乎修复了它。

steps:

脚步：

1. in the top left of xcode, click on "YOUR APP NAME | YOUR IPAD"
2. click "edit scheme"
3. select "Run YOURAPP.app" from the left column and get to the "info" tab
4. set the "build configuration" back to "debug"

1. 在 xcode 的左上角，单击“您的应用程序名称 | 您的 IPAD”
2. 点击“编辑方案”
3. 从左栏中选择“Run YOURAPP.app”并进入“info”选项卡
