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程序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

有任何想法吗?
