这事让我非常担心。我刚刚下载了iPhone 3.0 SDK，但现在我无法让我的配置文件工作。以下是我的尝试:
删除所有配置配置文件 删除登录keychain 创建新的“登录”钥匙链，使它 默认的 创建一个新的证书签名请求 创建新的开发人员和分销渠道 证书在苹果开发者中心 下载并安装它们 下载并安装WWDR证书 创建一个新的配置文件和 双击它来安装
所有的证书报告都是有效的，但是Xcode仍然不能识别它们。接下来我该试试什么?
编辑:
我完全重新安装了Mac OS X，从一个新的安装安装了3.0 SDK，仍然有同样的问题。

昨天也遇到了同样的问题。现在，在签署到开发人员门户之后，对于每个无效的配置概要都有一个按钮“Renew”。更新和下载更新后的配置文件似乎都能正常工作，所以问题肯定解决了:)
更新:你可能需要联系苹果来获得一个“更新”按钮，或者他们删除了它——解决方案是下载它并添加到钥匙链，不需要更新。

你试过重启你的Mac和设备吗?蹩脚的回答，但我总是先试一下。
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.
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。
如果你有新的mac，你可以去 IOS开发中心->供应门户->证书->开发->撤销并创建新证书。我的问题解决了。我的错误是“代码签名错误:身份'iPhone开发人员'不匹配任何有效的，未过期的证书/私钥对在您的钥匙串”
Because I keep coming back to this question, I will leave my answer here for the solution that works for me. It turns out that for a same public/private key developer identifier of me, it's installed twice in my keychain. Both have private key. But when I compare, one is private key of me within my developer organisation, and another one is private key of me as a personal developer. It turns out Xcode keeps trying using the wrong key. Removing the wrong duplicate key solves all the problem. Hey future me, check this one first next time!
