我已经重新绘制了NSWindow,现在当我启动我的应用程序时,控制台中有一个警告说NSWindow does not support utility styleMask 0x10.我怎么能摆脱这个警告？

// add the object to the mail app 
[[mail outgoingMessages] addObject: emailMessage];
emailMessage.visible = YES;

if ( [FileFullName length] > 0 ) {

    MailAttachment *theAttachment =

     initWithProperties:[NSDictionary dictionaryWithObjectsAndKeys:
                         FileFullName, @"fileName",nil]];
    // add it to the list of attachments 
    [[emailMessage.content attachments] addObject: theAttachment];
    [theAttachment release];
}

当我尝试设置visible属性时,我收到了错误消息:
