关于苹果开发证书失效的解决方案(2016年2月14日Failed to locate or generate matching signing assets)

前言:

从2月14日开始,上传程序的同学可能会遇到提示上传失败的提示.

并且打开自己的钥匙串,发现所有的证书全部都显示此证书签发者无效.

Failed
to locate or generate matching signing assets

Xcode attempted to locate or generate
matching signing assets and failed to do so because of the following issues.

Missing iOS Distribution signing
identity for ... Xcode can request one for you.

原因
& 解决方法:

原因是我们之前上传程序,都需要提前设置证书,而设置证书会涉及到从证书颁发机构申请证书.

参见我之前文章: http://blog.csdn.net/mr_lp/article/details/49784191


而失效的就是这个证书的签发者.



这时候我们前往我们的钥匙串,选择上方的
显示 --> 显示已过期证书



就会发现下面多出来了一个证书.



之后选择删除它,前往

https://developer.apple.com/certificationauthority/AppleWWDRCA.cer

去从新下载一个证书.



双击运行后即可,然而有的同学可能添加不成功.

那是因为你没有进行证书的权限设置.



添加成功后,就可以看见之前的证书全部有效了.

后记:

对此苹果官方的解释:
Thanks
for bringing this to the attention of the community and apologies for the issues you’ve been having. This issue stems from having a copy of the expired WWDR Intermediate certificate in both your System and Login keychains. To resolve the issue, you should
first download and install the new WWDR
intermediate certificate (by
double-clicking on the file). Next, in the Keychain Access application, select the System keychain. Make sure to select “Show Expired Certificates” in the View menu and then delete the expired version of the Apple Worldwide Developer Relations Certificate
Authority Intermediate certificate (expired on February 14, 2016). Your certificates should now appear as valid in Keychain Access and be available to Xcode for submissions to the App Store.

简单点说就是,你颁发开发者证书的根证书失效了,因为他会在2016年2月14日到期.
你之前以此***的证书才会全部失效.
