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。

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。

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

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!

以下是简单的步骤:

从计算机上的keychain(其中已经包含开发密钥)开始，创建一个证书请求。将请求上传到开发站点并创建证书。 使用证书创建配置文件。 下载配置文件并将其放到Xcode上。

现在所有的点都连接起来了，应该可以工作了。这对开发和推广都适用。

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。
