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。

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！

昨天我们的CI服务器也遇到了类似的问题。无法对应用程序扩展名进行错误签名

Code Sign error: No matching provisioning profiles found: No provisioning profiles with a valid signing identity (i.e. certificate and private key pair) matching the bundle identifier XXX were found.

注意:我自己从开发者门户网站创建了配置文件(不是由Xcode管理的)。

错误在于，我已经使用分发证书创建了供应配置文件，但是构建设置设置为使用开发人员证书。将其更改为使用分发证书解决了这个问题。

摘要:在生成设置中也要匹配用于创建配置文件的证书。

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。

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。

我花了几个小时处理这个fershluggage问题，它是在更新开发许可证后突然出现的。重申一下，一切都很顺利，然后(感谢苹果!)一切都搞砸了，一直搞砸下去。苹果官方的故障排除步骤(上面有链接)或这里提到的可能的解决步骤都没有为我解决这个问题。

最后，我删除了我的开发证书和发布证书，在配置门户中撤销它们，然后让Xcode自动刷新/发布它们。在任何顺序中，没有其他方法能够将所需的证书和私钥正确地连接到我的密钥链中。
