活动打开文件对话框前面的弹出对话框

Question

When the user opens some files, I use the open event in order to make some operations before enabling him to actually open. For that I have a progress dialog.

However, my dialog is always opened behind the open file dialog.

I've added the following code to windowDidLoad of my NSWindowController :

[NSApp activateIgnoringOtherApps:YES];
[[NSApplication sharedApplication] runModalForWindow:self.window];

But it didn't make any impact.

Open dialog:

How can I display my dialog in front? Note that my dialog is opened after it and closed before it.

在评论的帮助下，我发现在显示窗口之前添加以下行解决了该问题：

self.window.level = NSPopUpMenuWindowLevel;
