Question

使用IB绑定在NSTableColumn中对绑定数据进行排序。

键：NSTableColumn，排序，NSArrayController，内容集

contentSet就像TableColumn的数据源

这涉及一个带有两个单列NSTableViews的SplitView TableView的名称是BookCategory和图书。 Books Table有一个包含book_titles的列。 Class BookCategory具有一对多的关系预订。

BookCategory表使用以下方式在加载时排序：

@implementation MyBookCategoryController

- (id)init
{
    self = [super init];
    if (self) {
        // Initialization code here.
       NSSortDescriptor *descript = 
       [NSSortDescriptor sortDescriptorWithKey:@"name"
                    ascending:YES selector:@selector(caseInsensitiveCompare:)];

       [self setSortDescriptors:[[NSArray arrayWithObject:descript] autorelease] ];

    }
    return self;
}

This same approach fails to sort the BookTitle table at load.  !!

The BookTitle table/column loads unsorted.

For the TableColumn the Attributes Inspector has  
 Sort Key:title
 Selector: caseInsensitiveCompare:
 Order: Ascending

这似乎可以在单击时启用排序在列标题上。

I want the data sorted when the view loads. 

The binding inspector for this book_title column has:
 Value : BookCategoryArrayController.arrangedObjects.name

The BookTitleArrayController in binding inspector shows 
 Content Set: Book Category ArrayController.selection.books

重述问题，带有书名的tableview 加载未分类。它只在用户第一次点击后排序列标题。

假设有三种书籍类别艺术，历史，体育。当应用加载时，splitview中的左表被排序，那就是：

Art
History
Sports

当用户选择任何类别时，所有书籍的标题在类别中出现在右侧tableView但未排序。如果用户单击book_title TableColumn的Header 初始排序在列上完成。此后任何书籍类别的选择都会导致排序显示右侧tableView中的book_titles。也就是说，只有第一个选择类别会导致未排序的书名列表。

这是最终对我有用的概述。

            Sorting with CategoryArrayController (NSArrayController)

      Bindings Inspector
         Content Set  Bind to: CategoryArrayController.selection.books

         SortDescriptors Bind to: ShareUserDefaultsController
          Controller Key: values
          sortDescriptors  (note:  exclamation point)
          NSUnarchiveFromData

    Shared User Defaults Controller 
        Referencing Outlets
          userDefaultsController -- AppController (C:AppController)
        Referencing Bindings
            values.sortDescriptors -- Sort Descriptors Rx Array Controller (C:NSArrayController)
                                   -- Sort Descriptors Category Array Controller (C:NSArrayController)  

      Clicking on Category Header does no sort. Selects all in Cats, and empties Recipe Table
