如何以編程方式在文件和/或目錄中添加註釋？

Question

我想以編程方式在文件和目錄中添加註釋。

是否有可能呢？如果是，請幫助我實現這一點。我尋找從Cocoa框架直接API但沒有成功，我會很樂意以任何方式（可可，shell或任何腳本）做到這一點。

Answer 1

我實現這由Apple腳本包裹在Objective-C中：

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沒有公共API，如果谷歌的Spotlight註釋，你會看到這一切都是基於的AppleEvents，AppleScript的或XATTR各種解決方案..喜歡
