如何使用InterfaceBuilder綁定對NSTableColumn中的綁定數據進行排序？

使用IB綁定對NSTableColumn中的綁定數據進行排序。如何使用InterfaceBuilder綁定對NSTableColumn中的綁定數據進行排序？

鍵：NSTableColumn，排序，NSArrayController的，內容集

甲contentSet供應像TableColumn中

這涉及用兩個單柱NSTableViews 一個SPLITVIEW一個數據源的TableViews的名稱是BookCategory和書。 Books Table有一個帶有book_titles的單個列。 Class BookCategory對於Book有一對多關係。

的BookCategory表是使用在負載排序：

@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

這似乎使分揀當一個列標題點擊。

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

要重申的問題，與書名負荷排序，則實現代碼如下。只有在用戶首先點擊列標題後才能排序。

說有三個書類別藝術，歷史，體育。當應用程序加載左表的SPLITVIEW進行排序，那就是：

Art 
History 
Sports

當用戶選擇任何類別，在類別中的所有書籍標題出現在右邊的tableView但無序。如果用戶單擊book_title TableColumn 的標題，則在列上完成初始排序。此後，對任何書籍類別的選擇導致在右側tableView中book_titles的排序顯示。也就是說，只有第一個選擇的類別會導致未分類的書名稱列表。

非常感謝您的閱讀，馬克

這是我終於爲之工作的綱要。

  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
