Sorting Headers

Question

我有一個填充了數據的NSTable。我使用下面的代碼對列進行了排序。問題在於它按字母順序排列數字列，當我需要數字時。

(1,100,101,2,20,21,3,30,31................) 

我已輸入的數字(@1, @2, @3)而不是字符串(@"1", @"2", @"3")

// THIS WILL SORT ALL COLUMNS // 

- (void)tableView:(NSTableView *)tableView mouseDownInHeaderOfTableColumn:(NSTableColumn  *)tableColumn 

{ 

NSTableColumn *NumberColumn = [tableView tableColumnWithIdentifier:@"No."]; 
NSSortDescriptor *NumberSortDescriptor = [NSSortDescriptor 
            sortDescriptorWithKey:@"No." 
            ascending:YES 
            selector:@selector(compare:)]; 
[NumberColumn setSortDescriptorPrototype:NumberSortDescriptor]; 

NSTableColumn *CardNameColumn = [tableView tableColumnWithIdentifier:@"Card Name"]; 
NSSortDescriptor *CardNameSortDescriptor = [NSSortDescriptor 
             sortDescriptorWithKey:@"Card Name" 
             ascending:YES 
             selector:@selector(compare:)]; 
[CardNameColumn setSortDescriptorPrototype:CardNameSortDescriptor]; 

NSTableColumn *TypeColumn = [tableView tableColumnWithIdentifier:@"Type"]; 
NSSortDescriptor *TypeSortDescriptor = [NSSortDescriptor 
            sortDescriptorWithKey:@"Type" 
            ascending:YES 
            selector:@selector(compare:)]; 
[TypeColumn setSortDescriptorPrototype:TypeSortDescriptor]; 

NSTableColumn *RarityColumn = [tableView tableColumnWithIdentifier:@"Rarity"]; 
NSSortDescriptor *RaritySortDescriptor = [NSSortDescriptor 
             sortDescriptorWithKey:@"Rarity" 
             ascending:YES 
             selector:@selector(compare:)]; 
[RarityColumn setSortDescriptorPrototype:RaritySortDescriptor]; 

NSTableColumn *UnlimitedColumn = [tableView tableColumnWithIdentifier:@"Unlimited"]; 
NSSortDescriptor *UnlimitedSortDescriptor = [NSSortDescriptor 
             sortDescriptorWithKey:@"Unlimited" 
             ascending:YES 
             selector:@selector(compare:)]; 
[UnlimitedColumn setSortDescriptorPrototype:UnlimitedSortDescriptor]; 

NSTableColumn *FirstEditionColumn = [tableView tableColumnWithIdentifier:@"1st Edition"]; 
NSSortDescriptor *FirstEditionSortDescriptor = [NSSortDescriptor 
             sortDescriptorWithKey:@"1st Edition" 
             ascending:YES 
             selector:@selector(compare:)]; 
[FirstEditionColumn setSortDescriptorPrototype:FirstEditionSortDescriptor]; 

} 

- (void)tableView:(NSTableView *)tableView sortDescriptorsDidChange:(NSArray 
                  *)oldDescriptors 
{ 
[BaseSet sortUsingDescriptors: [tableView sortDescriptors]]; 
[tableView reloadData]; 

}

我想通了，我所有的代碼是正確這裏的數據。問題是我的應用程序在終止時保存了我的數組，並在將字符串轉換爲數字之前保存了它。
