错误：“没有可用于签名的身份” Xcode 4.3.1 [英] Error: "No identities are available for signing" Xcode 4.3.1

问题描述

我将我的OSX从Snow Leopard升级到Lion，我下载了Xcode 4.3.1
现在当我尝试验证并发布我的应用程序时，我得到了第一个屏幕截图。
如果我点击下载标识符按钮，我会得到第二个屏幕截图。

I upgraded my OSX from Snow Leopard to Lion and I downloaded Xcode 4.3.1 Now when I try to validate and publish my app I get the first screenshot. If I click on Download Identifier button I get the second screenshot.

有任何建议吗？

推荐答案

您为签署应用程序而创建的证书仅在您用于创建它们的计算机（+ OS）上有效。它们可以迁移到另一台机器但是如果你已经更新而没有这样做，我会认为这不再是一个选项了。我也不知道导入开发者资料按钮的作用（我猜这是相当新的），但你可以尝试一下。
如果这不能解决问题，请不要担心。只需登录您的ADC帐户，撤销旧证书，创建新证书并相应地修改您的项目。 （就像你刚开始创建时一样。）

The certificates you created for signing your application are only valid on the machine (+ OS) which you used to create them. They can be migrated to another machine but if you already updated without doing so, I recon that this is not an option anymore. I also don't know what the "Import Developer Profile" button does (I guess it's fairly new) but you could try that out. If this doesn't do the trick, don't worry. Just log on your ADC account, revoke the old certificates, create new ones and modify your project accordingly. (Just like you did, when you first created them.)
