手順 1：FlexGrid のデータソースの作成
- Project Navigator で、プロジェクト名を右クリックします。
- ［新しいファイル］を選択します。［新しいファイルのテンプレートを選択］ダイアログが表示されます。
- ［OS X］の下で、［ソース］→［Cocoa Touch クラス］を選択します。
- ［次へ］をクリックします。クラスに「CustomerData」と名前を付け、ドロップダウンのサブクラスで NSObject を選択します。
これで、CustomerData.h と CustomerData.m がアプリケーションに追加されます。新しいヘッダーと Objective-C ファイルを追加する方法については、「Objective-C による Xuni コントロールの追加」を参照してください。これらのファイルに次のコードを追加します。
#import <Foundation/Foundation.h>
@interface CountryPair: NSObject
@property NSString* title;
@property NSNumber* identifier;
@end
@interface CustomerData : NSObject
@property NSUInteger customerID;
@property NSString *firstName, *lastName, *address, *city;
@property NSUInteger countryID;
@property NSString *country, *postalCode, *email;
@property NSDate *lastOrderDate;
@property NSUInteger orderCount;
@property double orderTotal;
@property BOOL active;

+(NSMutableArray *) getCustomerData: (NSInteger) count;
+ (NSArray *)defaultCountries;
///TODO - remove obsolete properties and constructor
@end
#import "CustomerData.h"
@implementation CountryPair

手順 2：RowDetailsViewController テンプレートの追加
- Project Navigator で、プロジェクト名を右クリックします。
- ［新しいファイル］を選択します。［新しいファイルのテンプレートを選択］ダイアログが表示されます。
- ［OS X］の下で、［ソース］→［Cocoa Touch クラス］を選択します。
- ［次へ］をクリックします。クラスに「RowDetailsViewController」と名前を付け、ドロップダウンのサブクラスで NSObject を選択します。
