誰かがUISearchDisplayControllerのスコープボタンのドキュメントを指すことができますか？ Appleの例であるTableSearchを見ていますが、UISearchBarの下にスコープバーがどのように表示されるのかわかりません。スコープバーはUISearchDisplayControllerのスコープボタンを設定しますか？
All, Device, Desktop, Portable
です。AppDelegateとMainViewControllerのコードをコピーしました。これらのスコープボタンがどのように表示されているのか分かりません。 appDelegateで
、私は彼らのMainViewControllerクラスに続いて
- (void)applicationDidFinishLaunching:(UIApplication *)application
{
// Create and configure the window, navigation controller, and main view controller.
// Create the master list for the main view controller.
NSArray *listContent = [[NSArray alloc] initWithObjects:
[Product productWithType:@"Device" name:@"iPhone"],
[Product productWithType:@"Device" name:@"iPod"],
[Product productWithType:@"Device" name:@"iPod touch"],
[Product productWithType:@"Desktop" name:@"iMac"],
[Product productWithType:@"Desktop" name:@"Mac Pro"],
[Product productWithType:@"Portable" name:@"iBook"],
[Product productWithType:@"Portable" name:@"MacBook"],
[Product productWithType:@"Portable" name:@"MacBook Pro"],
[Product productWithType:@"Portable" name:@"PowerBook"], nil];
// Create and configure the main view controller.
MainViewController *mainViewController = [[MainViewController alloc] initWithNibName:@"MainView" bundle:nil];
mainViewController.listContent = listContent;
[listContent release];
// Add create and configure the navigation controller.
UINavigationController *navigationController = [[UINavigationController alloc] initWithRootViewController:mainViewController];
self.navController = navigationController;
[mainViewController release];
[navigationController release];
// Configure and display the window.
[window addSubview:navController.view];
[window makeKeyAndVisible];
、彼らは（製品の両方がNSStringsあるタイプと名前を持っている）、いくつかの製品データを設定参照してください。
