Question

我正在尝试从沙盒AppKit应用程序执行Automator工作流程。

最小示例+ github repo：

   NSOpenPanel * panel = [NSOpenPanel openPanel];
   [panel setAllowsMultipleSelection:NO];
   [panel setCanChooseFiles:YES];
   [panel setCanChooseDirectories:NO];
   [panel setAllowedFileTypes:[NSArray arrayWithObject: @"com.apple.automator-workflow"]];
    NSInteger result = [panel runModal];

    if (result == NSFileHandlingPanelOKButton) {
      NSURL * workflow = [[panel URLs]objectAtIndex:0];
      NSLog(@"selected url %@", workflow);
      NSError * error = nil;
      [AMWorkflow runWorkflowAtURL:workflow withInput:[NSArray arrayWithObject:workflow] error:&error];
      if(error) {
          NSLog(@"Error while executing workflow %@", [error localizedDescription]);
      }        
    }

根据我目前对AMWorkflow API的理解，我假设它使用Mach IPC在单独的Automator Runner流程中执行工作流程。

这就是为什么我向我的应用添加了以下权利：

   <key>com.apple.security.temporary-exception.mach-lookup.global-name</key>
   <array>
     <string>com.apple.AutomatorRunner</string>
     <string>com.apple.Automator</string>
   </array>

但显然Automator Runner尝试连接回调用的应用程序失败并出现以下错误信息：

Automator Runner(2717) deny mach-lookup  /Users/pbrc/Library/Developer/Xcode/DerivedData/AMWorkflowCaller-arjgkslqihljquelyvybmpsnljrn/Build/Products/Debug/AMWorkf

6   Automator Runner                0x0000000100001a51 -[AMRunnerDelegate processArguments] + 487

有什么想法吗？

简单的答案是AMWorkflow API在沙盒应用程序中不起作用。最近推出了一种替代API，它适用于沙盒应用程序：

NSUserAutomatorTask executeWithInput:completionHandler:

使用此API，您可以执行位于应用程序脚本文件夹中的自动机脚本：

/ Users / USERNAME / Library / Application Scripts / BUNDLENAME.APPNAME

有一个重要的警告：尽管方法的“输入”参数没有输入将被传递到10.8.3 12D75之前的Mac OS版本上的automator工作流程（这是/是一个错误）：

NSUserAutomatorTask * task = [[NSUserAutomatorTask alloc] initWithURL:workflow error:&error];
if(error) {
    NSLog(@"Error while creating script task %@", [error localizedDescription]);
}

[task executeWithInput: @"this will never reach your workflow" completionHandler:^(id result, NSError *error){
    if(error)
        NSLog(@"Error while executing workflow %@", [error localizedDescription]);
}];

将AMWorkflow与沙盒应用程序一起使用
