Jenkins 集成Xcode 项目的时候在证书上遇到了问题。实际上如果在本地的话。只要Xcode工程里选择了项目就不需要重新设置证书了。jenkins会自动找到这个证书，只要在build setting 里设置的是正常的。
并且在xcode 里能正常编译。

Check dependenciesCode Sign error: No codesigning identities found: No codesigning identities (i.e. certificate and private key pairs) that match the provisioning profile specified in your build settings (“qingyunDeveloper”) were found.

如果遇到类似的错误 解决办法：
首先打开keychain keys 找到apple 的开发者证书。然后复制。 再选择左边的系统（system）把刚复制的证书放进去。
如果这个还没有解决。
接下来第二步：
找到你用户下的Provisioning Profiles 文件。目录为 /Users/xxx/Library/MobileDevice/Provisioning Profiles  xxx表示你自己的用户名

把这里面所有的证书复制到/Users/Shared/Jenkins/Library/MobileDevice/Provisioning Profile   这个文件。


最后提示

iPhone.build/ProjectCos.xcent /Users/chenqing/Sqy/iOSProject/cyou/Svn/Cos/CosXCode_lxh/build/ProjectCos.app** BUILD SUCCEEDED **Finished: SUCCESS

This week I setup the Jenkins on my Mac and try to build iOS applications. unfortunately I got the code signing issues, either I use xcode plugin or xcode command line tool. Through a couple days of googling and I could not find any solution that works for me, but I finally solve this issue by myself through different try out, and the solution is such an easy, now I would like to share with my solution.

The core reason is Jenkins is running as daemon mode in Mac, just assume it is a different user - "Jenkins", so it will not have access to the keychain or provision profile as a you login using your credentials, which cause the code signing issue.
I found I have following 2 errors

1. "Code Sign error: There are no valid certificate/private key pairs in the default keychain"
Solution: Copy your iPhone developer certificate from "login" keychain to "System" keychain.
Detailed steps:
  open the "Keychain Access" application, click the login tab, right click the certificate like "iPhone Developer: your_name (XXXXXXX)", choose copy, then click the "System" tab, right click mouse, choose "Paste 2 items"; you might need to do the same thing with the certificate like "iPhone Distribution: your_name".

After doing this, you will get the second error.
2. "Code Sign error: Provisioning profile ‘xxxxx-xxxx-xxxx-xxxxx‘ can‘t be found"
Solution: Copy the provision profile to Jenkins user folder.
The provision profile is under in the folder
/YourUserName/Library/MobileDevice/Provisioning Profiles,
for example in my machine, the provision profile files are under /Users/steve/Library/MobileDevice/Provisioning Profiles
In the mac, the Jenkins will be in /Users/Shared/Jenkins, create the following folder:
/Users/Shared/Jenkins/Library/MobileDevice/Provisioning Profile,  then copy the .mobileprovision file to this folder.

After doing this, the code signing issues will be fixed. Hope my finding will be helpful to other Jenkins users.
