objective-c - 将 AMWorkflow 与沙盒应用程序结合使用

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 进程中执行工作流。

这就是我向我的应用添加以下权利的原因:

   <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 尝试连接回调用应用程序，但失败并显示以下错误消息:

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

有什么想法吗？

Answer 1

简单的答案是 AMWorkflow API 无法在沙盒应用程序中工作。最近推出了一个替代 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化脚本:

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

有一个重要的警告:尽管该方法有“输入”参数，但在 10.8.3 12D75 之前的 Mac OS 版本上，任何输入都不会传递到自动化工作流程(这是/曾经是一个错误):

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]);
}];
