我参考这个链接 Command /usr/bin/codesign failed with exit code 1 and Xcode Error: Command /usr/bin/codesign failed with exit code 1 but not find solution。我花了很多时间来解决和尝试这个问题，但我无法解决它。
错误如下。
/Users/macmini2/Library/Developer/Xcode/DerivedData/CliniCalc-euqpjsnetzgblefamkvsxhinzomp/Build/Products/Debug-iphoneos/CliniCalc.app: The operation was cancelled by the user.
Command /usr/bin/codesign failed with exit code 1
我使用 Xcode 5.1。
