2014年8月1日

サンプルコード：
RViewController1 *vc1 = [[RViewController1 alloc]init];

UINavigationController *navController = [[UINavigationController alloc]initWithRootViewController:vc1];
//tabBarItem.titleに値を割り当てる
//navController.tabBarItem.title = @"Page 1″;

//tabBarItem.titleとnavigationItem.titleに値を割り当てる
navController.title = @"Page 1″;
navController.tabBarItem.image = [UIImage imageNamed:@"1.jpg"];

RViewController2 *vc2 = [[RViewController2 alloc]init];
vc2.title =@"Page 2″;
// UITabBarItem *item2 = [[UITabBarItem alloc]initWithTitle:@"Page 2″ image:[UIImage imageNamed:@"2.png" ] selectedImage:[UIImage imageNamed:@"2_pressed.png"]];
vc2.tabBarItem.image = [UIImage imageNamed:@"2.png"];

RViewController3 *vc3 = [[RViewController3 alloc]init];
vc3.title =@"Page 3″;
vc3.tabBarItem.image = [UIImage imageNamed:@"3.png"];

RViewController4 *vc4 = [[RViewController4 alloc]init];
vc4.title =@"Page 4″;
vc4.tabBarItem.image = [UIImage imageNamed:@"4.png"];
vc4.tabBarItem.badgeValue = @"10″;

RViewController5 *vc5 = [[RViewController5 alloc]init];

//UITabItemのインスタンスを作成
UITabBarItem *item1 = [[UITabBarItem alloc]initWithTabBarSystemItem:UITabBarSystemItemHistory tag:0];
vc5.tabBarItem = item1;

NSArray *controllers = [NSArray arrayWithObjects:navController,vc2,vc3,vc4, nil];

UITabBarController *tabController = [[UITabBarController alloc]init];
tabController.viewControllers = controllers;

self.window.rootViewController = tabController;
