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。
当前回答
对我来说，只有当证书和两个密钥都在Login keychain中时，它才有效。我之前创建了一个开发钥匙链，但是Xcode管理器在那里找不到钥匙。所以我把它们移回登录，退出钥匙链工具-瞧，Xcode管理器中的错误消失了!这是在3.1.3 SDK的雪豹10.6.2上。
其他回答
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”
以我为例，我把这个项目从我的iMac复制到我的Macbook Pro，然后发现我的Macbook上没有安装我的私钥。所以我导出了我的私钥，复制并安装到Macbook上，瞧，它工作了!我在这里记录了这些信息: http://www.creatistblog.com/2009/09/iphone-developer-provisioning.html
我解出来了。 我不得不把。cer文件拖到KeyChain Access中。但请确保左上角的“Login”已被选中。否则，Xcode将无法看到证书，也就无法为你的代码签名。
苹果在这方面还有改进的空间....
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！
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。
