我有一台苹果机，用Xcode 4开发iPhone应用。 我现在有一台新麦金塔电脑，新安装了……一切。
当打开在旧Mac上构建的Xcode项目时，我无法在配置为开发版iPhone的iPhone上运行应用程序。 Xcode 4管理器告诉我在配置文件中“没有找到有效的签名标识”。
我猜这与我之前在旧Mac上生成的.certSigningRequest文件有关(我有该文件的备份)，但我必须在新Mac上处理它吗?
另一件奇怪的事情是，我在管理器中看不到我的5个现有配置文件(在苹果配置门户上定义)，即使刷新并输入我的配置门户登录名和密码后:

我解决了“有效的签名身份未找到”错误或多或少:
Make sure that the certificate in your iOS developer program is also listed in your keychain access and is valid (compare the issue dates). If it is not, either transfer it from your old mac using the instructions from apple reference OR delete it from the website and your keychain access and then recreate it, re-download it and drag it over Xcode. Delete any existing development or distribution provisioning profiles and recreate them based on your new certificate, redownload them and verify from keychain access that everything is valid.

I had the same error but the issue was slightly different. We have a team of developers but we all use the same Apple ID (Developer Account), so when I generated the Provisioning profile, I kept getting the same error as in the subject question. Then although I had downloaded the certificate (that gets prompted as part of the Development Provisioning Assistant steps), I was still getting that error. Then I found the issue was that our Apple Developer account was using a Certificate that was generated on my work mate machine, so I needed to revoke it, and generate a new certificate, then create the provisioning profile.
摘要，从中得到的教训是，用于配置配置文件的证书必须在将使用配置配置文件的同一台计算机上生成。当你有一个开发团队共享同一个Apple ID时，这一点尤其重要。 希望它能帮助到一些人
我对这个错误的2分，即使与导出/导入场景无关:
当添加移动供应证书(即PROV文件)时，不要将文件从Finder拖到Keychain Access。相反，只需双击Finder中的PROV文件，同时保持Keychain Access应用程序在某处运行。
事实上，我曾在Keychain中看到我之前的供应项目(带有黄色灯的那个)被一个新的、具有相同名称和应用ID的绿色项目所取代。HTH
我今天也遇到了类似的问题。不幸的是，我的HD死在我身上，所以我不能在接受的答案中做这里提到的迁移。我必须执行以下步骤:
连接到苹果开发者成员中心，然后连接到iOS 临时门户。 吊销我的证书。 通过提供一对新的私钥和公钥来创建一个新的证书。 删除之前的所有配置文件并创建新的配置文件。 下载新的配置文件，并通过拖动将它们安装到Xcode中 他们到Xcode图标在码头。
这篇文章也提到了同样的动作。

未找到有效的签名标识
请参阅苹果公司公布的解决此问题的步骤。
关于你在iOS Portal上的“5个现有配置文件”的问题，这些配置文件在Xcode 4的本地库中是缺失的。x Organizer > Devices选项卡下的库> Provisioning Profile部分。
我建议你遵循以下步骤，恢复丢失的配置文件，也包括Xcode错误的情况下，Xcode 4.1-4.2.1错误地删除你的本地库配置文件在iOS Portal上是“活动的”。
