如何以编程方式在文件和/或目录中添加注释？

Question

我正在尝试以编程方式在文件和目录中添加注释。

有可能吗？如果是，请帮助我实现这一目标。

我从Cocoa框架中寻找了一个直接的API，但没有成功，我很乐意以任何方式（可可，shell或任何脚本）这样做。

Answer 1

我用Objective-C包装的Apple Script实现了这个目标：

 NSString *comment = @"hi boys";

NSOpenPanel *op = [NSOpenPanel new];
NSInteger answer = [op runModal];
if (answer == NSOKButton) {
    NSURL *url = [op URL];

    NSMutableString *appleScriptString = [NSMutableString new];
    [appleScriptString appendString:@"TELL APPLICATION \"FINDER\"\n"];

    NSString *setPath = [NSString stringWithFormat:@"SET filePath TO \"%@\" AS POSIX FILE \n", [url absoluteString]];
    [appleScriptString appendString:setPath];

    NSString *setComment = [NSString stringWithFormat:@"SET COMMENT OF (filePath AS ALIAS) TO \"%@\" \n", comment];
    [appleScriptString appendString:setComment];

    [appleScriptString appendString:@"END TELL"];

    NSAppleScript *commentorScript = [[NSAppleScript alloc] initWithSource:appleScriptString];
    NSDictionary *dictErr;
    [commentorScript executeAndReturnError:&dictErr];
    NSLog(@"Dict error = %@", dictErr);
}

AFAIK没有公共API，如果你谷歌搜索Spotlight评论，你会看到各种解决方案，所有解决方案都基于AppleEvents，Applescript或xattr ..喜欢
