如何以编程方式在文件和/或目录中添加注释？

问题描述：

我试图以编程方式在文件和目录中添加评论。

I am trying to add comment in files and directory programmatically.

可以吗？如果是，请帮助我实现这一点。

Is it possible to do? If yes, please help me to achieve this.

我从Cocoa框架寻找一个直接的API，但没有成功，我会很乐意做任何方式，shell或任何脚本）。

I looked for a direct API from Cocoa framework but no success, I will be happy to do this by any way (cocoa, shell or any scripts).

我通过包装在Objective-C中的Apple Script实现了这一点：

I achieved this by Apple Script wrapped in Objective-C as :

 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);
}
