我有一个NSWindowController的子类，它有自己的nib，另一个类有一个IBAction来显示窗口并像这样加载它。
if (!propertiesController){
propertiesController = [[PropertiesController alloc] init];
}
[propertiesController showWindow:self];
这是第一次，但在我关闭窗口并再次调用此方法后，窗口不会显示。我确信窗户不会被打开。我是否必须覆盖showWindow才能将窗口排序到前面？还是我必须指定控制器在笔尖中使用的窗口？
你试过了吗
[propertiesController.window makeKeyAndOrderFront:self];
？
