一、項目結構
一開始創建一個空的項目
二、主要代碼
1、AppDelegate.m
- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions { self.window = [[UIWindow alloc] initWithFrame:[[UIScreen mainScreen] bounds]]; UITabBarController *tabBarController = [[UITabBarController alloc] init]; FirstViewController *one = [[FirstViewController alloc] init]; one.title=@"聯系人"; one.tabBarItem = [[UITabBarItem alloc] initWithTabBarSystemItem:UITabBarSystemItemContacts tag:0]; UINavigationController *navFirst = [[UINavigationController alloc] initWithRootViewController:one]; [tabBarController addChildViewController:navFirst]; SecondViewController *two = [[SecondViewController alloc] init]; two.title=@"收藏"; two.tabBarItem = [[UITabBarItem alloc] initWithTabBarSystemItem:UITabBarSystemItemFavorites tag:1]; UINavigationController *navSecond = [[UINavigationController alloc] initWithRootViewController:two]; [tabBarController addChildViewController:navSecond]; self.window.rootViewController=tabBarController; self.window.backgroundColor = [UIColor whiteColor]; [self.window makeKeyAndVisible]; return YES; }
2、FirstViewController.m
- (void)viewDidLoad { [super viewDidLoad]; UIBarButtonItem *rightButton = [[UIBarButtonItem alloc] initWithBarButtonSystemItem:UIBarButtonSystemItemAdd target:self action:@selector(selectRightAction:)]; self.navigationItem.rightBarButtonItem = rightButton; } -(void)selectRightAction:(id)sender { ChildViewController *childViewController; childViewController =[[ChildViewController alloc] initWithNibName:@"ChildViewController" bundle:nil]; childViewController.title=@"添加聯系人"; [self.navigationController pushViewController:childViewController animated:YES]; }
3、SecondViewController.m
默認內容
4、ChildViewController.m
默認內容
三、運行效果
1、初始界面
2、進入第一個視圖的子視圖
3、切換到第二個視圖
