UITabBarControllerの使い方

HooコントローラとFooコントローラを持つUITabBarへ移動

-(IBAction)HogeAndFooPressed:(id)sender {
    //---------------------------------------------------------------------------//
    // HogeViewControllerとFooViewController生成
    //---------------------------------------------------------------------------//
    HogeViewController *hogeViewController = [[HogeViewController alloc] init];
    FooViewController  *fooViewController  = [[FooViewController  alloc] init];
	
    //---------------------------------------------------------------------------//
    // タブバー生成を生成してHogeViewControllerとFooViewControllerを登録
    //---------------------------------------------------------------------------//
    UITabBarController *tabController = [[UITabBarController alloc] init];
    NSArray* controllers              = [NSArray arrayWithObjects:
                                           hogeViewController,
                                           fooViewController,
                                           nil
                                        ];
    tabController.viewControllers     = controllers;
	
    //---------------------------------------------------------------------------//
    // navigationControllerにタブバーをpush
    //---------------------------------------------------------------------------//
    [self.navigationController pushViewController:tabController animated:YES];
    
    
    // リリース
    [tabController release];
}

説明

navigationControllerにpushするのはHogeViewControllerとFooViewControllerを持ったタブバー

[self.navigationController pushViewController:tabController animated:YES];

各自のタブをHogeViewController, FooViewControllerが自分自身で作る。

HogeViewController.m

- (id)initWithNibName:(NSString *)nibNameOrNil bundle:(NSBundle *)nibBundleOrNil {
	self = [super initWithNibName:nibNameOrNil bundle:nibBundleOrNil];
	if (self) {
		UIImage* anImage = [UIImage imageNamed:@"Hoge.png"];
		UITabBarItem* theItem = [[UITabBarItem alloc] initWithTitle:@"Hoge" image:anImage tag:0];
		self.tabBarItem = theItem;
		[theItem release];
	}
	return self;
}

FooViewController.m

- (id)initWithNibName:(NSString *)nibNameOrNil bundle:(NSBundle *)nibBundleOrNil {
	self = [super initWithNibName:nibNameOrNil bundle:nibBundleOrNil];
	if (self) {
		UIImage* anImage = [UIImage imageNamed:@"Foo.png"];
		UITabBarItem* theItem = [[UITabBarItem alloc] initWithTitle:@"Foo" image:anImage tag:0];
		self.tabBarItem = theItem;
		[theItem release];
	}
	return self;
}
