xcode 4.2 ios5 codesign失败，退出代码为1

我在谷歌搜索了一个适合我的解决方案......我尝试了很多不同的建议......但似乎没有任何效果。

I've searched all over the google for a solution which works for me... I've tried SO many different suggestions.. but nothing seems to be working.

在我尝试运行项目时使用ios5的xcode 4.2中，我收到以下错误

In xcode 4.2 using ios5 when I try to run the project, I get the following error

    CodeSign /Users/matt/Library/Developer/Xcode/DerivedData/myapp-apjchwtbrxazuighfwhrzxchpcfk/Build/Products/Debug-iphoneos/myapp.app

我试过了

• 重新安装xcode


• 删除DerivedData文件夹


• 添加资源位置文件（某处？！）


• 检查重复的info.plist文件


• 创建一个symm（？）链接到代码签名文件夹


• 其他随机小位和bobs

• reinstalling xcode
• deleting the DerivedData folder
• adding resource location files (somewhere?!)
• checking for duplicate info.plist files
• creating a symm (?) Link to the code sign folder
• other random little bits and bobs

似乎什么都没有用！我认为我没有改变任何东西，因为这不起作用。我正在我的iPhone 4S上测试，然后在iPhone 3G上尝试（操作系统3.1.2） - 我实际上更改了设置以添加armv6，但是试图将其更改为无效。

It seems nothing is working! I don't think I changed anything for this not to work. I was testing on my iPhone 4S, then tried on an iPhone 3G (os 3.1.2) - I actually changed the settings to add armv6, but have tried to change this back with no avail.

我不知道我现在能做什么？！

I'm not sure what I can do now?!

感谢您的帮助....任何事情都可以！

Thanks for any help.... anything at all!
