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！

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。

我登录了开发人员帐户并撤销了开发证书。撤销和下载开发证书后，我双击新下载的证书，这一次私钥在开发证书下的KeyChain访问。

我发现我需要拖动distribution_identity。我从开发人员程序门户网站上的“Certificates -> Distribution”页面下载的cer文件到密钥链访问程序中，然后这个错误就消失了。

我也有同样的问题，但是，这是由于我在我的Mac上设置了“FileVault”。我进入我的钥匙链，将“login”设置为默认值，这就解决了它。
