从父视图控制NSTabViewController

问题描述

（我正在使用情节提要和快捷方式。）

我目前有一个NSWindowController，其中有一个NSTabViewController作为contentViewController。
我现在正在尝试通过使用

  let tabController = self.contentViewController作为代码通过代码从NSWindowController更改选项卡！ NSTabViewController 
 tabController.tabView.selectTabViewItemAtIndex（1）
  

但TabView不会更改视图。

我使用的API错误吗？

解决方案

I找到了关于此主题的

更新11 / 16/2016 ：

据Apple称，这不是错误，而是预期的行为。他们正在更新文档。

(I'm using storyboards and swift.)

I currently have a NSWindowController which has a NSTabViewController as contentViewController.I am now trying to change the Tabs from the NSWindowController via code using

let tabController = self.contentViewController as! NSTabViewController
tabController.tabView.selectTabViewItemAtIndex(1)

but the TabView doesn't change the view.

Am I using the API wrong?

解决方案

I found an forum post about this topic. There seems to be a bug when setting the tabView index in combination with using NSTabViewController.

Their solution is to select the tab via the controller itself instead of its tabView.This can be done by using the selectedTabViewItemIndex property.

So your code would be the following:

if let contentViewController = self.contentViewController as? NSTabViewController {
    contentViewController.selectedTabViewItemIndex = 1
}

I am going to file a radar on this and you should do the same. This really seems to be a bug, not a misuse of the API.

Update 11/10/2016:
The issue seems to be fixed partly. (macOS Sierra 10.12.1) The method now selects the tab, but the selection in the tab bar does not update..

Update 11/16/2016:
According to Apple, this is not a bug but intended behaviour. They are updating the documentation.
