objective-c - 从服务启动时出现 OSX 代码签名无效异常

Question

MyApp 是一个音盒应用程序，具有文件和文件夹 服务功能。当我正常启动应用程序时，应用程序工作正常，但当它被服务调用时，它会使 Finder 在几秒钟内无响应，然后崩溃

控制台日志显示以下崩溃

这清楚地表明它存在一些代码签名问题

Exception Type: EXC_CRASH (Code Signature Invalid)

下一个自然步骤应该是检查其签名，因此我使用了 spctl 并且它返回了

$ sudo spctl --assess --verbose=4 /Applications/MyApp.app
/Applications/MyApp.app: accepted
source=Developer ID

我不知道这里缺少什么。

更新

我在我的计算机上创建了一个新帐户并运行该应用程序，并且没有收到任何协同设计错误/异常。

所以这与用户帐户的状态有关，或者可能是 OSX 的错误。

Answer 1

我怀疑您的服务正在启动您的应用程序的未签名副本，该副本位于您的开发目录中。

您的第一次崩溃表明路径是:

/Users/USER/Library/Developer/Xcode/Archives/2015-02-02/MyApp 02-02-2015 6.02 pm.xcarchive/Products/Applications/MyApp.app/Contents/MacOS/MyApp

您发布的 spctl 命令检查了签名:

/Applications/MyApp.app.  

当您以开发者帐户登录时，该服务可能会从您的 Xcode/Archive 目录中获取未签名的应用程序并失败。在/Applications 中手动启动已安装的版本，或对该版本进行 spctl 检查，都会成功。使用不同的用户帐户时，该服务可能会在/Applications 中找到该版本。
