codesign CSSMERR_TP_NOT_TRUSTED

codesign -s "Developer ID Application: Mide Hu" "/Users/QtDev/11/build_trial/list.app"

Xcode iOS真机调试出现

Command /usr/bin/codesign failed with exit code 1

查看详细信息提示：CSSMERR_TP_NOT_TRUSTED

出现这一问题的原因可能是：
（1）证书“Developer ID Application: Mide Hu" 是无效的！
  (2) 缺少”Apple Woldwide Developer Relations Certification Authority“



================================================================
以下是备注：

查了点资料，发现原来之前在keychain(钥匙窜访问)中多删了一个证书：Apple Woldwide Developer Relations Certification Authority，它是iPhone Developer证书的签发者，如果它被删除就会导致iPhone Developer证书被识别为未知颁发机构签名，然后xcode中真机调试就会出现上面的错误。解决方法当然是重新把AppleWWDRCA放回去

从Apple官网下载一个

找到 Woldwide Developer Relations 选择 Download certificate

下载后拖入keychain(钥匙窜访问)－登录目录。
