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。

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!

我也遇到了同样的问题:我第一次是在跑步时把证书下载到我的小MacBook上的。当我试图在iMac上安装证书时…然后我遇到了这一页上描述的问题。
和你们很多人一样，我花了几个小时把头发揪出来，然后我按照下面的步骤来解决它:
Close all your stuff except your webpage that should be logged into App Dev center. Open Xcode. Click WINDOW > ORGANIZER. Then click the Devices tab and select "Provisioning Profiles" on the left. That should bring up your provisioning profiles. Highlight one by one (if more than 1), right click and delete profile. Yes, just do it! Delete them all! (I kept making a new one after a new one trying to make the thing work.) From the first page you see after logging into the App Dev Center on the right side click "iOS PROVISIONING PORTAL" > (do not "launch assistant"). Instead click on the left side. Select CERTIFICATES. You will probably have just one line listed with your name/company - from there click on the right side REVOKE. Click OK to verify that's what you want to do. On the same page click DEVICES. Click the box next to your device you are trying to provision and click REMOVE SELECTED. Again click OK to verify. Wait about 2 minutes to let Apple do their thing. Now click on "HOME" that is on the left side navigation. Click "Launch Assistant" create a new app ID - call it whatever you want. Just make sure it's unique enough to know that's the one you just created because the others you've been messing with all day will not be deleted from Apples Dev Center. You should be able to follow the rest of the Assistant without troubles -- the main thing is you just had to delete your old provision profiles and start over.
好运！
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”
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。
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。
我得到的最佳答案是导出您的密钥，而不是仅仅试图导入证书文件。
当您从生成请求的密钥链中导出密钥时，您将得到一个Certificates。P12文件，将需要的键滚动在一起。
然后将其导入新计算机。
对于这样的密钥，最好保留一个滚动的证书包文件，因为很多时候“公共”密钥或证书文件不足以进行恢复。
