对于开发证书，您只需创建一个新的证书并将其与配置文件匹配即可。但是对于分发，就像你要提交给苹果时，你不能这样做，必须使用团队代理创建的分发证书。问题是您需要计算机上的私钥。这很简单，但是，创建证书的团队代理复制私钥给你，下面是来自Apple的说明，我希望这对你有帮助。

It is critical that you save your private key somewhere safe in the event that you need to develop on multiple computers or decide to reinstall your system OS. Without your private key, you will be unable to sign binaries in Xcode and test your application on any Apple device. When a CSR is generated, the Keychain Access application creates a private key on your login keychain. This private key is tied to your user account and cannot be reproduced if lost due to an OS reinstall. If you plan to do development and testing on multiple systems, you will need to import your private key onto all of the systems you’ll be doing work on.

To export your private key and certificate for safe-keeping and for enabling development on multiple systems, open up the Keychain Access Application and select the ‘Keys’ category. Control-Click on the private key associated with your iPhone Development Certificate and click ‘Export Items’ in the menu. The private key is identified by the iPhone Developer: public certificate that is paired with it. Save your key in the Personal Information Exchange (.p12) file format. You will be prompted to create a password which is used when you attempt to import this key on another computer. You can now transfer this .p12 file between systems. Double-click on the .p12 to install it on a system. You will be prompted for the password you entered in Step 4.

以下是我所做的。

Make sure your certificates have not expired, make sure you delete all the expired ones. Get new ones etc, Once you have make sure all that is the way it should be, then focus on your project files. in finder , go to your .xcodeproj files then show package contentes. open project.pbxproj in xcode or textedit. find every refrense to PROVISIONING_PROFILE and remove the GUID, just leave empty "" Depending on your project you should have about 12+ refrences, remove all of the GUIDS. Save file, then reopen your project in XCODE Re select the correct provision profiles for all possible code signings( they should not all be the same) Build your project and you should be good to go.

我认为Xcode在某种程度上混淆了，从项目中删除了所有的Provision Profiles。Pbxproj，然后重新选择一个有效的配置文件将使它直。

在仔细浏览了这里的主题并检查了人们提出的所有解决方案后，我可以自信地断言，在遵循苹果开发者文档中提到的创建CSR和移动供应文件的步骤后，就这样做吧!，

Xcode发射。 选择窗口- >组织者 点击这个刷新按钮，肮脏的黄色条将立即删除。

相信我，你只需要这么做。没有必要一遍又一遍地重复这个过程来确保你的方法是正确的。只需按下刷新，输入您的登录凭证，就完成了。

这里的每个人都错了。你所需要做的就是按照苹果在“管理你的数字身份”中提供的步骤操作。

它指导你通过Xcode导出你的证书，并通过Xcode重新导入。它工作得很好，但要确保你的用户名在两台电脑上是相同的，否则就会失败。

你需要:

1)私钥和公钥。

你的钥匙链上有这个符号

2)由这些密钥的签名请求生成的证书

3)连接到该证书的配置文件

假设你换了电脑，想重新设置Xcode配置文件。你是怎么做到的?

Open Xcode, press ctrl + O to open the Organizer, and delete all provisioning profiles you might have installed already. Open keychain access, and create a signing request which you save to file (when you create the request, a private and public key is created in your keychain). Create/Update a certificate in the provisioning portal by sending apple this signing request Download and install the newly created certificate. Revoke your provisioning profiles and update them with the new certificate. Download and install the newly updated provisioning profiles.

我也遇到了同样的问题，试过了所有方法。不管出于什么原因，解决方案是我所有的证书都迁移到一个名为“microsoft_intermediate_certificates”的密钥链上。因为它可能发生在Xcode升级期间，我完全不知道为什么，但它可能会帮助到一些人。

我将微软钥匙串的所有内容移动到登录钥匙串，一切恢复正常。
