添加导航栏到Tap吧

Question

我想要一个公共导航栏到RecieptViewController和StockViewController，并且栏应该包含后退按钮以返回到InventoryViewController ..... 此代码是在InventoryViewController viewDidLoad中编写的： -

RecieptViewController *firstVC=[[RecieptViewController alloc]init];
UITabBarItem *itme1=[[UITabBarItem alloc]initWithTitle:@"First" image:nil tag:1];
itme1.title=@"Reciept";
[firstVC setTabBarItem:itme1];

StockViewController *secondView=[[StockViewController alloc]init];
UITabBarItem *item2=[[UITabBarItem alloc]initWithTitle:@"Second" image:nil tag:2];
item2.title=@"Stock";
[secondView setTabBarItem:item2];

[tapBarController setViewControllers:[NSArray arrayWithObjects:firstVC,secondView,nil]];

Answer 1

如果要向UITabBarController添加导航控制器，则必须尝试以下操作：

UIViewController *viewController1, *viewController2;
UINavigationController *navigationController1, *navigationController2;

viewController1 = [[RecieptViewController alloc] initWithNibName:@"RecieptViewController" bundle:nil];
viewController2 = [[StockViewController alloc] initWithNibName:@"StockViewController" bundle:nil];

navigationController1 = [[UINavigationController alloc] initWithRootViewController:viewController1];
navigationController2 = [[UINavigationController alloc] initWithRootViewController:viewController2];

[tapBarController setViewControllers:[NSArray navigationController1,navigationController2,nil]];
