如果我从菜单上援引,为什么主要寡妇是无效的?
原标题:Why mainWindow is null if I invoke it from the menu?

I m invoking the same IBAction from 2 different xib files (the main window and the main menu).

- (IBAction)showEditor:(id)sender
{
 ...    [document mainWindow]; 
}

然而,当我从菜单上显示主妇时,主妇就是无效的。 但我不理解:b 两个轴心档案都是在 app开始时启动的,因此,在我点击菜单时,所有文件都应先入。

感谢

或许document? 这将解释为什么<代码>[主要寡妇文件]无效。 参看<代码>文件的两例。
