因为我还没有看到这个具体的答案:

我的问题是我需要手动签名。所以我的错误是在构建设置->代码签名->代码签名标识

我有我的调试(自动签名风格，和苹果开发证书)，分期和发布(手动和苹果分发(adHoc)变种设置正确。

我没有正确设置(由于我理解中的一些有缺陷的逻辑)是“任何IOS SDK”的值。一旦我将其设置为相同的手动Apple Distribution证书，错误就消失了。

最初我把它设置为自动值“iOS分布”，因为我认为它会更好地自动处理，因为我不知道它是什么意思。还是不要。哦，希望能有所帮助

Delete the developer certificate that does not have a private key. Delete the provisioning profile from your machine using go to folder (~/Library/MobileDevice/Provisioning Profiles) Then first check then uncheck the Automatically manage signing option in the project settings with selecting team. Sing in Apple developer account and edit the provisioning profile selecting all available developer certificates then download and add to XCODE. Select the provisioning profile and code signing identity in project build settings

对于那些仍然在Xcode8中与这个问题作斗争的人。对于我来说，这是一个重复的证书问题，这是我解决它的方法:

我读了尼克的回答，然后开始了我的调查。我检查了我的特定案例中的所有密钥和证书(在~/Library/Keychains/System.keychain中)。

When I opened the file, I found that I had two iPhone Distribution Certificates (that was the certificate that Xcode was requesting me), one with the iOS Distribution private key that I have been using since the beginning, and another iPhone Distribution Certificate which its private Key had a name (iOS Distribution:NAME) that wasn´t familiar for me. I deleted this last certificate, started Xcode again and the problem was gone. xCode wasn´t able to resolve that conflict and that´s why it was giving signing certificate error all the time.

检查你的钥匙链，也许你有一个重复的证书。

为了解决这个问题，

我只是在项目设置通用选项卡上启用了“自动管理签名”，在启用之前，我担心它可能会有一些副作用，但一旦我启用，它就为我工作了。

检查您的钥匙串，查找缺少私钥的身份。我为同一个团队安装了多个分发证书，其中一个缺少私钥。Xcode只检查密钥链中第一个匹配的标识，并自动使用这个标识，而不是包含私钥的标识。

删除没有私钥的匹配标识使Xcode再次检测到正确的标识。

此问题是由于您的配置文件中的证书中的私钥与您的密钥链中的私钥不匹配。我解决这个问题的方法是

delete all iPhone Developer certificate in keychain. delete all certificate in apple account. using xcode "Manage Certificates" to add certificate, sometime you still have certificate in your Mac, but I do not know where it is for now, and if added successfully, your apple account will display that certificate too, and then you can create your profile with that certificate and download ... goto 5 if you use "Manage Certificates" can't add certificate, you can create a new certificate, and do remain steps. finish.

Xcode版本8的代码签名问题也是如此。
